1. vegetative growth refers to the development stage from germination to flower bud differentiation. In the vegetative growth stage, the apical meristem of plants is controlled by auxin, cytokinin and other plant hormones to differentiate into cell tissues and grow upward, and is also influenced by external factors.
2. Reproductive growth means that plants begin to differentiate flower buds and gradually form flowers under the control of hormones in the body. After fertilization, sperm and egg combine, and this combination is called fertilized egg. The zygote and ovule together form a seed. The integument is the seed coat.
Everything that drives the growth of plants comes from nature, and soil only provides the substrate for the growth of plants. Nutrients in the soil and carbon dioxide and sunlight in the air are the basis of plant growth.
Plants absorb water, minerals and inorganic substances in the soil through roots, then absorb carbon dioxide through leaves, then carry out photosynthesis through sunlight, and finally convert these nutrients into organic substances and store them in plants. With the continuous transformation and accumulation of organic matter, plant cells grow and divide, and then plants grow from small to large, and then blossom and bear fruit.
