Plants have a life cycle, just like humans and other animals. The life cycle of a plant describes the different stages of the plant from the beginning of its life to the end, that is, from the seed to the mature plant. However, not all plants produce seeds. Some plants, such as ferns or mosses, produce different types of cells called “spores.”.
These plants do not produce seeds. The life cycle of the plant begins with a seed. From the outside, the seeds are protected by a hard layer, called the outer layer. But inside each seed is a tiny baby plant, known as an embryo.
The embryo has a root, a bud and the first true leaves. Did you know? Before a seed germinates, it is INACTIVE (i.e., alive but inactive). For germination, seeds need a suitable condition, that is,. Water, correct temperature and correct location (for example, on the ground).
When the right conditions for the seed are met, it will begin to sprout. The first root begins to grow downward. There are few tiny hairs on the roots that absorb water and minerals from the soil. The seed sprouting process, usually after a dormant period, is called germination.
A very young plant that grows after germination. It starts to grow towards the sunlight. Plants need sunlight, nutrients, water and air to survive and grow. Photosynthesis helps the seedling to grow into a mature plant.
When a plant matures, it begins to flower (in a flowering plant) and the flowers produce seeds. A mature plant has leaves, roots, stem, flower and fruits. Flowers are the reproductive part of a plant. It produces seeds that in turn produce new plants.
There are different parts of a flower, such as petals, sepals, stamens, pistils, etc. Pollination plays a very important role in the life cycle of plants. Flowers use pollen to produce seeds through a process called pollination. Pollen is transferred by different pollinators, such as birds, butterflies, insects, bees or even the wind.
So when pollen passed from stamen to pistil, it's called pollination. And once pollination occurs, the seeds start to grow. Finally, the seeds are dispersed (dispersed) in new places and the plant's life cycle begins anew. Seeds can spread through animals, wind and water.
Did you know? The fruit of the dynamite tree (also known as the sandbox tree) explodes with a strong blow and shoots seeds 100 feet away. Plants that don't produce the flowers and seeds to reproduce are called seedless plants. Like ferns or mosses, they produce different types of cells called “spores”. The plant life cycle begins when a seed falls to the ground.
There are many different types of plant life, but flowering plants, or angiosperms, are the most advanced and widespread because of their amazing ability to attract pollinators and spread seeds. Flowers are more than beautiful objects to look at or decorate; they have a very important purpose in plant reproduction. The main stages of the flower life cycle are the stages of seed, germination, growth, reproduction, pollination and seed propagation. To complete the growth phase of the flower life cycle, plants must produce their own food.
As soon as the leaves emerge, they begin the process of photosynthesis. Plants contain chloroplasts in leaves, which convert energy from sunlight, carbon dioxide and water into sugars, which they use as food. Plants store sugars in their roots and stems. The root system continues to develop, anchoring the plant to the ground and growing root hairs that help the plant better absorb water and nutrients.
The stem grows longer towards the sun and transports water and food between the roots and leaves. Sugars and starches are transformed into energy that is used to grow new plants. New leaves grow on the top of the stem or meristem. After a while, cocoons develop.
Some plants flower in a few days, while others take months or even years. Some flowers have only male parts and others only female parts. In others, the masculine and feminine structures are widely separated. These plants rely on insects, birds, animals, wind, water, or other pollinators to carry pollen from male flowers or male parts to female flowers or female parts.
Without pollinators, there would be no seeds or new plants in these plant species. Even flowers that can self-pollinate benefit from being fertilized by the pollen of a different plant, which is called cross-pollination, because cross-pollination results in stronger plants. After planting it in the ground for a few days, the seed absorbs water and swells until the seed coat splits. It is important that the seed is planted in the right place at the right time for it to germinate.
