Stems usually differentiate into short nodes and long nodes. Stem has the function of transporting nutrients and water and supporting leaves, flowers and fruits in a certain space. Some stems also have the functions of photosynthesis, nutrition storage and reproduction.
Leaves are one of the vegetative organs of vascular plants, which can synthesize organic matter through photosynthesis and have transpiration to provide power for roots to absorb water and mineral nutrients from the outside. Flowers are unusually short branches with reproductive function.
Extended data:
The fruit of a plant is developed from the pistil of a flower, and the seeds of most plants are wrapped in the fruit. The "fruit" of strawberry grows from the receptacle, which is an exception. The number of seeds in a fruit varies, some have only one seed, and some have many seeds.
When fruits are ripe, some fruits are rich in water, while others are dry. Fruits with water are usually brightly colored and can attract animals to eat. When the seeds are excreted, they will take root and sprout.
Some leguminous plants and other plants will come out of generate after the fruits are ripe, shoot their seeds nearby and wait for the chance to germinate. Some fruits are very light in weight, and when the wind blows, they will be carried far away by the wind to complete the task of carrying on the family line.
