Question: ______ are the three parts of the seed.
Options:
cotyledon, zygote and ovule
cotyledon, radicle and ovule
cotyledon, embryo and ovule
cotyledon, zygote and radicle
-Cotyledon, radicle and ovule are the three parts of the seed.
-The radicle is the embryonic root of the plant, and grows downward in the soil (the shoot emerges from the plumule).
-Above the radicle is the embryonic stem or hypocotyl, supporting the cotyledon(s).
-It is the embryonic root inside the seed.
🔴Additional Information:
✏️A seed has three parts:
-Seed Coat
-Endosperm
-Embryo
-A seed coat protects the internal parts of a seed.
-The seed coat has two layers.
-The outer layer is thick and known as the testa.
-The inner layer is thin and known as tegme.
-The endosperm contains the nutrients stored in it.
-It provides nutrients to the seed in the form of starch, carbohydrates and proteins to support the embryo during germination.
-It is located below the seed coat.
✏️An embryo comprises the following parts:
-Epicotyl
-Hypocotyl
-Radicle
-Cotyledons
