1. 1. Wrong. Only plant cells containing chloroplasts can carry out photosynthesis. 2. no. Starch is the product of photosynthesis. 3 wrong, using water and carbon dioxide can only synthesize sugars under the catalysis of enzymes, and other substances cannot be synthesized.

2. 1. The upper surface of leaves is dark and contains more chlorophyll.

2. The stomata of plants are relatively small. When it rains, the guard cells absorb enough water to open the stomata, and then the excess water in the plant will be discharged.

3. The workshop is mesophyll cells, the machine is chloroplast, the raw materials are water and carbon dioxide, and the products are oxygen and organic matter.

This is the phototropism of plants, which can make plants get more sunlight for photosynthesis.

5. Breathing decomposes organic matter to release energy, and the organic matter here comes from photosynthesis of plants.
