The first step in plant growth is germination, which is the process by which a seed develops into a seedling. When a seed is planted, it absorbs water and begins to sprout. The first thing that emerges from the seed is the radicle, which is the primary root of the plant. The radicle then grows down into the soil, anchoring the plant and absorbing water and nutrients. Next, the hypocotyl emerges from the seed. The hypocotyl is the stem of the plant, and it grows up towards the sun. The first leaves of the plant, called cotyledons, then develop on the hypocotyl. Cotyledons are simple, often heart-shaped leaves that provide the plant with its first source of food.

Vegetative Growth

After the seedling has emerged from the soil, it enters a period of vegetative growth. During this time, the plant produces new leaves and stems. The leaves are responsible for photosynthesis, which is the process by which plants use sunlight to convert carbon dioxide and water into sugar and oxygen. The stems support the leaves and transport water and nutrients from the roots to the leaves.

Flowering

When the plant is mature, it will produce flowers. Flowers are the reproductive organs of plants, and they contain the pollen and ovules that are necessary for fertilization. Pollination occurs when pollen is transferred from the male anther to the female stigma. Once the pollen has been transferred, the ovules can be fertilized and the seeds can begin to develop.

Fruiting

After the flowers have been pollinated, they will develop into fruit. Fruit is the mature ovary of a flower, and it contains the seeds of the plant. Fruit is often brightly colored and fleshy, which helps to attract animals that will eat the fruit and disperse the seeds.

Seed Dispersal

Once the seeds have been dispersed, they can germinate and begin the cycle of plant growth again.
