Leaf growth process

Leaves grow on branches, there are buds on branches, and buds have bud primordium. Nutrients transported by leaves and roots grow into tender leaves and grow into new leaves later.

After a period of dormancy, the seeds of a tree will germinate and grow radicle, embryo and hypocotyl, and then gradually form roots, leaves and trunk. After that, the leaves of the tree began to carry out photosynthesis, and the oil glucose in the body was converted into protein. Finally, the cells gradually began to divide, with lush leaves and thick branches.

Extended data:

Plant growth process: it includes four complete growth processes: germination stage, leaf unfolding stage, flowering stage and fruiting stage.

1. Germination stage: Plants first grow vegetative organs such as roots, stems and leaves from seed germination.

2. Leaf development stage: after the radicle germinates, it first goes deep into the soil to form the main root, and then the hypocotyl elongates, pushing the cotyledons and germs out of the soil surface to form the leaves of plants.

3. Flowering period: After a certain period of vegetative growth, some parts of plants feel the changes of external conditions such as light and temperature, and flowers begin to form through the induction of some hormones.

4. Seed-setting stage: Through various pollination, pollen reaches the stigma of stamens, which stimulates the stigma to produce pollen tubes and carries the male ovule to ovule for fertilization. After fertilization, the egg cells begin to develop, and after a certain period of time, the ovule and various parts form fruits.
