NEET BIOLOGY

Detailed explanation-1: -It stores food and has the potential to develop into a new plant under optimal conditions. Fertilization is the process of fusion of male gamete and female gamete to form a zygote. Pollen grains are transferred to stigma by various pollinating agents such as water, wind, butterflies, insects, animals, birds, etc.

Detailed explanation-2: -Not all plants produce seeds, but those that do often rely on these seeds to replicate themselves over successive seasons and years. 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.

Detailed explanation-3: -Seed dispersal promotes the survival of plant species. It allows plants to unfold in an extensive area. Thus, preventing plants from competing for light, water, and nutrients from the soil, which occurs when plants grow closer to each other.

Detailed explanation-4: -Seeds are the products of ripened ovule. Seeds contain two cotyledons or a single cotyledon as in cereals which help in providing food to the embryo (baby plane). These cotyledons are enclosed within the seed coat which also acts as a protective layer. On germination, seeds give rise to new baby plant.

Detailed explanation-5: -The embryo plant is protected by seeds, which allows it to develop once it finds adequate soil. Seeds are a protective structure that allows a plant embryo to live for a long time before germinating. Until the embryo’s growing conditions are favourable, the seed can remain dormant.
