Question 2: What are the plants that eat insects? Wonderful insect-eating plants
There are more than 500 kinds of plants that feed on animals all over the world, among which the insect traps of pitcher plants are the most exquisite and complicated. Nepenthes is an epiphyte and climber. Most of them grow in humid tropical forests such as Indian Ocean Islands, Madagascar, Sri Lanka and Indonesia, and there are also such plants in Guangdong, Yunnan and other provinces in China.
Nepenthes are generally less than one meter high, and some are as high as three meters. The leaves are oval, with a length of 10-25cm and a width of 4-8cm. The top end of the blade is connected with a downward bending tendril, and the top end of the tendril is provided with an insect trap. The insect trap is cylindrical, slightly enlarged at the lower part, and some are like pig cages, so it is called pitcher plants. In Hainan, locals often call it Leigong pot, which means it is like a pot used by farmers to hold wine. It thunders and rains in rainy days, and the insect trap is filled with rain, just like a hip flask filled with wine. If it rains too much, the tendrils will automatically tilt and pour some water out of the bag. This is beneficial to play the role of insect catching bag, because if the bag is full of water, insects can easily climb out and escape after falling into the water.
Nepenthes eat insects because of its peculiar leaves. The midrib of its leaves sticks out and becomes tendrils, which can be attached to other things to rise. A capsule is produced at the top of the roll, like a milk bottle, with a lid on the mouth that can be opened and closed. The edge of the bottle mouth is rolled inward, and there is half a bottle of water in the bottle. The inner wall of the bottle mouth can secrete sweet honey juice, and greedy insects will crawl over to eat honey when they smell the fragrance. Maybe just when they were having fun, they suddenly slipped and plunged into the bottle, stuck in the water, and could never escape. The inner surface of the lower half of the insect trap has a slightly thick wall and many digestive glands. These glands have secreted a slightly sticky digestive juice, which is stored at the bottom of the trap when insects do not fall into it. The digestive juice is acidic and has the ability to digest insects. Some people think that after insects fall into the capsule, the capsule cover will automatically close. It's not that sensitive.
Other insect-eating plants, such as sundew, felt moss, venus flytrap, etc. They can also catch insects, but their insect catching tools are far less sophisticated than Nepenthes.
Question 3: What are the names of plants that eat insects? Editor's entry Cordyceps sinensis is a famous tropical insect-eating plant, mainly produced in tropical Asia. Nepenthes has a unique organ that absorbs nutrients-insect trap. The insect trap is cylindrical, and the lower part is slightly enlarged, so it is also called Nepenthes. Hainan, the origin of China, is also called Leigong pot, which means like a hip flask. This kind of plant is called an insect-eating plant. It does not directly absorb nutrients needed to sustain life from inorganic fields such as soil, but lives by catching small animals such as insects. The scientific name Nepenthes. Distilled grass (cultivated as N. zeylanica) is also known as pitcher plant, monkey water bottle, monkey adult, pitcher plant, worry-free girl and so on. Taxonomy: Eukaryotes: Plants: Angiosperms: Dicotyledons: Dianthus: Nepenthes: Nepenthes. Botanical characteristics: Nepenthes often grows creeping in nature, and the stem plants are generally less than 1m, but there are also more than 3m in different varieties. Leaves: alternate, oblong, long 10 cm -25 cm, wide 4 cm -8 cm. The structure of leaves is complex, including petiole, leaf body and tendrils. The top of the leaf is connected with tendrils bent downward, and the tail of the tendrils is unfolded and rolled back to form a bottle, which is the insect trap. The midrib of the leaf extends like a red plastic rope, which is the climbing organ of pitcher plants. It can be wrapped around other objects or lying on rocks. Insect trap: Nepenthes insect trap is 12cm- 16cm long and 2cm-4cm wide. The color of the cage is mainly green with brown or red spots and stripes, and there is a hat at the top. The capsule cover is oval or oval, with a length of 2.5-3.5 cm. When the insect trap is small, the cover is sealed, and it can only be opened when it grows out. Only one place is connected with the mouth of the insect trap. And after opening, it will not be closed at will. Flowers: Nepenthes flowers are unisexual, with racemes of red or purplish red flowers, sepals but no petals. When mature, racemes are born in the axils of leaves, with single flowers, small flowers, red or purple, and seeds after flowering. Male flower: Male flower has 4 sepals, oval or oblong, 5cm-7cm long. The filaments of stamens combine to form a tube, and the anthers gather to form a ball. Female flower: Female flower has small sepals, oval pistil, black and dense hair. Nepenthes fruit splits into four petals at maturity, dark brown, long 1.5cm-3cm, and there are many filamentous seeds inside. Nepenthes preys on Nepenthes. There are nectar glands in the insect trap, which can secrete nectar to attract insects. After the insects enter the insect trap, the capsule cover is not closed as people think, but the inner wall of the insect trap is smooth, so the insects can be prevented from climbing out. There is often half water in the bag. When there is too much water, the tendrils can't bear the load and will automatically tilt and pour some water. Because if the bag is full of water, insects can easily escape after falling into the water. The inner wall of the lower half of the insect trap is slightly thicker, and there are many digestive glands, which secrete slightly viscous digestive juice and store it at the bottom of the insect trap. The digestive juice is acidic and has the ability to digest insects. In fact, the main purpose of opening the capsule cover is to attract insects, because there are also many nectaries on the inner wall of the capsule cover. Most of the insects falling into the bag are ants, and there are some flying insects such as wild flies and mosquitoes. There are many species of Nepenthes in the growing environment, and there are about 100 species in the world. Most of them grow in humid tropical forests such as Indian Ocean Islands, Madagascar, Sri Lanka and Indonesia, and are also found in China, Hainan, Guangdong and Yunnan provinces. I like warm, humid and semi-cloudy environment. Not cold-resistant, afraid of dryness, afraid of strong light. The optimum growth temperature is 25-30℃, 2 1-30℃ from March to September, and 18-24℃ from September to next March. In winter, the temperature should not be lower than 16℃, the plants stop growing below 15℃, and the leaf edges below 10℃ suffer from freezing injury. Cordyceps sinensis is a kind of compositae herb, which can grow to 1 m high and have small yellow flowers with hundreds of flower heads per plant. & gt
Question 4: What flowers can eat worms? The following flowers can eat worms:
1. Lysimachia latifolia
Plants rely on the photosynthesis of chlorophyll to make nutrients, but a few plants can prey on small insects to absorb nutrients. Salsola salsola is such an insect-eating plant, which can catch insects and then secrete liquid to digest and absorb the nutrition of insects.
2. Di Chin Luo
Miandiluo is an insect-eating plant, which often grows on grassland or wet rocks and sand. Gemdale's leaves are laid flat on the ground in a rosette shape, with broad spoon-shaped leaves and covered with glandular hairs on the edges. When an insect falls in, glandular hairs will surround the insect's body, and sticky glands will stick the insect. The secreted liquid can decompose nutrients such as protein, and then be absorbed by leaves.
common nepenthes
It is an interesting phenomenon that plants can prey on animals and insects. In addition to Lauraceae, Nepenthes is another herb with the ability to prey on insects. There are about 67 species of Nepenthes in the world, and only one species is produced in Guangdong, China. Nepenthes often grows horizontally in nature, with complex leaf structure, petiole, leaf body and tendrils, and the tail of tendrils expands and folds back to form a bottle shape, which can prey on insects. Nepenthes have racemes and small green or purple flowers. The bottle-shaped body at the top of Nepenthes leaves is a tool for preying on insects. The opening edge and cap of the bottle can secrete honey and attract insects. The bottle mouth is smooth, the insects slide into the bottle and are submerged by the liquid secreted by the bottom of the bottle, and the nutrients of the insects are decomposed and gradually digested and absorbed.
4. Utricularia flavescens
Insect-eating plants in water should belong to urapidae. Utricularia is submerged except inflorescence, and there are oval insect traps on the leaf organs, which can catch tiny insects or zooplankton in the water. In summer and autumn, the inflorescence sticks out of the water and has yellow lip-shaped flowers.
Eargrass
Saxifraga is a herbivorous plant, which grows in swamps and wetlands. It is an annual dwarf herb with erect stems and creeping branches. Insect traps are born on creeping branches of leaf organs. Because it eats insects, there are no big leaves with chlorophyll, and there are a few small yellow flowers on the branches. In the fruit, the calyx grows and droops like a spoon that digs the ear.
Question 5: What are the insect-eating plants that can eat insects? There are quite a few kinds of insect-eating plants. Common ones are: Lauraceae, Nepenthes, Bottle Grass, Utricularia, Corydalis, etc.
Insect-eating plants are autotrophic plants, which obtain nutrients (non-energy) by capturing and digesting animals. Insect-eating plants mostly prey on insects and arthropods. It grows in areas with poor soil, especially nitrogen-deficient areas, such as acid swamps and rocky desertification areas. 1875, Charles? Darwin published the first paper on insect-eating plants. This insect-eating plant can attract and catch prey, and can produce digestive enzymes and absorb decomposed nutrients. It is distributed in 10 family, about 2 1 genus, with more than 630 species. In addition, more than 300 genera of plants have the function of catching insects, but they do not have the ability to digest prey, so they can only be called insect-catching plants. Some Nepenthes can occasionally prey on small mammals or reptiles, so insectivorous plants are also called carnivorous plants.
Question 6: What insects do insect-eating plants usually eat? Insect-eating plants include pitcher plants and flycatchers. Eat mosquitoes, flies and bugs. Hope to adopt
Question 7: Which leaves will eat insect-eating plants, such as Venus flytrap, sundew (Cape of Good Hope with spoon leaves and toothbrush, Cape of Good Hope, Florrie in Haobai Mong Kok), Echinacea purpurea, Corydalis apple and hairy winter bud.
Question 8: Why do some plants eat insects? Some plants in nature can also eat meat and insects, which are called insect-eating plants or carnivorous plants, and there are more than one kind. There are about 400 species of plants that can eat insects in 4 families, and there are about 30 species in 3 families in China, mainly including felt moss, sundew, flytrap, pitcher plant, pitcher plant, insect trap, Vaccinium bracteatum and so on. How do these plants catch and digest insects? Different plant forms have different ways to catch insects. But they are very sensitive to insects that fall on them, which will cause morphological changes. They stick or clamp insects with insect catching leaves and secrete digestive juice to digest insects. Their insect traps are all made of abnormal leaves, which are called insect catching leaves. Insect catching leaves are saccular (such as Utricularia), discoid (such as Lauraceae) and bottle-shaped (such as Nepenthes). Here are some typical ways to catch insects. The insect catching leaves of Lysimachia angustifolia are half-moon or disc-shaped, and there are many touching hairs on the upper surface that can secrete mucus, which can stick to insects, and at the same time, the touching hairs can bend automatically, surround insects and secrete digestive juice for digestion and absorption. More interestingly, it grows better when small fresh meat is fed to sundew and felt moss. The insect-catching leaves of Nepenthes are bottle-shaped and have complex structures. There is a lid on the top of the bottle, and the belly of the lid is smooth and glandular. The bottle cap is usually open. Once a bug climbs to the bottle mouth, it can easily slide into the bottle and be digested and absorbed by digestive juice. Carnivorous plants have insect-catching leaf structure, which is the result of long-term adaptation to the environment and natural selection. Carnivorous plants generally have chloroplasts, which can produce organic matter through photosynthesis, so they can survive even if they can't get animal food, but when they have appropriate animal food, they can produce more fruits and seeds.
Question 9: What are the names of plants that can eat insects? Plants that can eat insects are: Venus flytrap, Nepenthes, etc.
