Generally speaking, plant organs can be divided into two categories, one is vegetative organs and the other is reproductive organs. Plant organ: 1. Roots: Roots are underground forms of plants, which mainly play the role of fixation and absorption, and can also synthesize and store organic matter for vegetative reproduction. 2. Stem: The stem is the skeleton of the aboveground part of the plant, on which leaves, flowers and fruits grow. It has the functions of transporting nutrients and water and supporting leaves, flowers and fruits in space. Some stems also have photosynthesis. 3. Leaves: Leaves are the main organs of photosynthesis in plants. The leaves of northern plants will fall off due to seasonal changes. Of course, the plants in the south do not mean that the leaves will not fall off, which is related to the pigments in the leaves. Reproductive organs: 1. Flowers: Flowers are the reproductive organs of plants. Includes calyx, corolla, stamens and pistils that produce germ cells. Flowers spread pollen through bees, butterflies and wind. 2. Fruit: Fruit is an organ developed from the pistil of angiosperms after pollination and fertilization. Generally speaking, fruits, including peels and seeds, have the function of reproduction and reproduction. 3. Seeds: Seeds are unique propagules of gymnosperms and angiosperms, which are formed by pollination and fertilization of ovules. Seeds generally consist of seed coat, embryo and endosperm. New plants can grow when planted in soil.
