Oct 19, 2023 · The process by which a seed transforms into a plant (seedling) in optimum sunlight, air, and water is called germination. The seed can grow within its range of minimum and maximum temperatures. Any temperature above this range can either damage the seeds or make them dormant.

The life cycle of a flowering plant begins with a seed. It has a protective outer covering called the shell. Inside the shell contains the baby plant or the developing embryo and the endosperm that contains reserve food. The endosperm nourishes the embryo with necessary food and water during its development. Seeds are dispersed or spread in various...
Next, the planted seeds germinate, forming a seedling. The four key environmental factors necessary for seed germination are oxygen, water, sunlight, and appropriate growth temperature. When all these four factors are ideal, the seeds sprout to form a seedling. Initially, the rootpushes its way through the seed coat and starts growing downwards int...
After successful germination, a delicate, young plant called the seedling starts making its way out of the ground towards sunlight. As it grows, the seedling derives all its essential nutrients from the soil through its roots. The growing plant traps sunlight with the help of a pigment called chlorophyll. These pigments, which are found in their le...
The process of photosynthesis allows the young, developing plant to grow into an adult plant gradually. A fully mature plant consists of roots, stems, and leaves. The roots derive nutrients and water from the soil, while the stemcarries them to the leaves. The leaves perform photosynthesis to prepare food in the form of carbohydrates. In a flowerin...
A fully mature flowering plant now participates in reproduction, which occurs by pollination. Pollination is when pollens are picked from the anther of a flower and transferred to the stigma of the same or different flower. Various pollinating agents, such as bees, butterflies, insects, birds, and animals, including humans, perform pollination. Whe...
3 days ago · Germination, the sprouting of a seed, spore, or other reproductive body, usually after a period of dormancy. The absorption of water, the passage of time, chilling, warming, oxygen availability, and light exposure may all operate in initiating the process.

Feb 2, 2023 · Have you ever noticed a new plant to grow from the seed you have thrown away after eating? The process through which a new plant develops from its seed is called seed germination.
The embryo inside the seed starts to grow into a seedling. Roots grow down to anchor the plant in the ground. Roots also take up water and nutrients and store food. A shoot grows skywards and develops into a stem that carries water and nutrients from the roots to the rest of the plant.
