What are the four characteristics of seeds?

All seed plants have seeds which contain an embryo, a seed coat and stored food. The seed coat protects the seed, allowing it to remain dormant until the weather is just right for germination. At that point, the leaves of the embryo absorb water and the radical or root emerges, shortly followed by the plumule or shoot.

What are the 4 factors for seeds to germinate?

There are four environmental factors that affect seed germination: Water, Light, Oxygen, and Heat.

What are the 4 factors required for germination of seed?

All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.

What factors do seeds need to grow?

Water, temperature, oxygen, and light (only for some seeds) are the essential conditions for the germination process. The absence of one or more of these affects the sprouting of seeds.

What does a seed contain?

Most seeds consist of three parts: embryo, endosperm, and seed coat. The embryo is a tiny plant that has a root, a stem, and one or more leaves. The endosperm is the nutritive tissue of the seed, often a combination of starch, oil, and protein.

What are the functions of seed?

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 is the structure of a seed?

The seed consists of three components: embryo, endosperm (sometimes perisperm), and seed-coat. Both endosperm and embryo are the products of double fertilization, whereas the seed-coat develops from the maternal, ovular tissues. The seed habit is a significant advancement in the evolution of higher plants.

What is seed and its function?

The seed in a plant is the part that develops from the ovules after fertilization. They are enclosed in the fruit which develops from the fertilized ovary. The seeds are formed as a result of sexual reproduction and contain the young embryo which can develop into a new plant.
