The vegetative organs of plants are mainly composed of roots, stems and leaves. Roots are the longest growing parts of plants, which mainly absorb water and nutrients in the soil. Stem is formed by the development of seed germ, which can transport water, inorganic salts and organic matter, and also play a role in supporting plants. Leaves are the main places for photosynthesis and respiration of plants.

Vegetative organs of plants

The main organs of plants are divided into vegetative organs and reproductive organs. Vegetative organs are mainly composed of roots, stems and leaves. They cooperate and promote each other, ensuring that sufficient water and nutrients can be transported in plants, maintaining normal growth and development, and some vegetative organs of plants can reproduce into new individuals.

Roots are the first part of plants in the process of growth, which are mainly composed of taproots, lateral roots and adventitious roots. Through the process of growth, differentiation and absorption, roots can absorb water and nutrients in the soil and promote the normal growth of plants. When a plant needs self-regulation, it will grow into an aerial root.

There are four types of internodes on the stem: erect, climbing, winding and creeping. They are usually developed from the germ of seeds, which can transport nutrients absorbed by roots to the whole plant and store nutrients at the same time, and the mechanical tissue under the skin can play a supporting role.

Leaf is the main place for photosynthesis and respiration of plants, which is mainly composed of leaves, petioles and stipules. The pores on the surface can evaporate water and promote breathing. The osmotic pressure in epidermal cells can control the opening and closing of pores and complete the absorption of water and oxygen.
