Analysis:

Angiosperms are divided into dicotyledonous and monocotyledonous, and their basic differences are as follows:

magnoliopsida

Root, taproot, fibrous root system

Stem vascular bundles are arranged in a ring, cambium vascular bundles are scattered, and cambium is absent.

Leaves with reticulate veins, veins flat or curved.

The radix of each part of the flower is 4 or 5, and the radix of each part is 3.

Pollen grains have three germination holes, and pollen grains have only one germination hole.

Embryo has 2 leaflets, 1 leaflet.

The above differences are not absolute, but actually overlap, such as hairy root plants such as Ranunculaceae, Plantago asiatica and Compositae in dicotyledonous plants; Plants with dispersed vascular bundles such as Zanthoxylum, Nymphaeaceae, Ranunculaceae and Dianthus; Flowers of Lauraceae, Magnoliaceae, Berberidaceae and Ranunculaceae have three cardinal numbers; Nymphaeaceae, Ranunculaceae, Polygonaceae, Papaveraceae and Umbelliferae all have L-shaped leaves. Among monocotyledonous plants, Araceae, Liliaceae, Dioscoreaceae and so on. There are reticular veins; 4 cardinal flowers such as POTAMOGETON, Liliaceae and Stemonaceae.
