They help in germination of the new plant . The seeds contain food reservoirs in the form of cotyledons and endosperm. The seed coat is protective in nature which protects the embryo inside.
What is the function of a seed?
Functions. Seeds serve several functions for the plants that produce them. Key among these functions are nourishment of the embryo, dispersal to a new location, and dormancy during unfavorable conditions .
What are the parts of the seed and its function?
The three primary parts of a seed are the embryo, endosperm, and seed coat . ... The endosperm is a source of stored food, consisting primarily of starches. The seed coat consists of one or more protective layers that encase the seed. A seed begins to form an embryo following fertilization and the start of a zygote.
What is in a seed?
Seeds have a seed coat which protects them while they grow and develop, usually underground. Inside the seed there are is an embryo (the baby plant) and cotyledons . When the seed begins to grow, one part of the embryo becomes the plant while the other part becomes the root of the plant.

Seeds are of immense biological and economic importance. They contain high protein, starch and oil reserves that help in the early stages of growth and development in a plant. These reserves are what make many cereals and legumes major food sources for a large proportion of the world's inhabitants.
What is the function of the fruit?
The function of fruits: A fruit protects the immature seeds from animals and extreme climatic conditions . It stores food material. It attracts animals that help in dispersing or scattering the seeds to distant places.
How a seed is formed?
Seeds are the result of plant reproduction . ... When pollen lands on the flower's stigma, it germinates and forms a pollen tube, which then quickly grows towards the plant's ovary. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation.
