Seed (Define)
The fertilized, ripened ovule of a flowering plant containing an embryo and capable normally of germination to produce a new plant.
The grain or ripened ovule of plants used for sowing.
Seed Coat (Define)
The seed is enclosed in the seed coat; it is used to protect the inner parts of the seed. Seed coats can vary in thickness, texture, colour, etc.
Endosperm (define)
Food storage for the seed. Can be made up of proteins and carbohydrates. Nourishes the seed during its dormant stage and importantly at the beginning of the plants life.
Embryo (Define)
Contains pre-cursor tissues necessary for growth of other key parts like roots, stems, and leaves.
Germination
Germination occurs when a plant starts to grow. Seeds remain dormant until something kick starts the process, like weather or seed scarification. Some seeds evolved to require animal guts to start, and ensures they are widely dispersed.
Roots
Any subterranean plant part, especially when fleshy and edible.
The usually underground part of a seed plant body that originates usually from the hypocotyl and functions as an organ of absorption and food storage and a means of anchorage and support. It different from a stem in lacking buds, nodes and leaves.
How do roots form?
Roots begin to form from the embryo of the seed. The first thing to emerge from the seed coat is the radicle from the embryo, which develops into the primary root.
