Explanation of Seed Parts:
Cotyledon(s):
The cotyledons are the first leaves of the plant embryo within the seed. They serve as storage organs that provide nutrients to the developing embryo during the early stages of growth. The number of cotyledons can vary between plant species. In dicots, there are typically two cotyledons, while in monocots, there is only one. These food stores are crucial for the embryo’s initial growth before the plant can begin photosynthesis.
Radicle:
The radicle is the embryonic root of the plant. It is the first part of the seed to emerge during germination and grows downward into the soil to anchor the plant and begin absorbing water and nutrients. The radicle will eventually develop into the root system of the mature plant.
Plumule:
The plumule is the embryonic shoot of the seed, which will develop into the stem and leaves of the mature plant. It is located above the radicle and is responsible for growing upwards toward the light, where it will begin the process of photosynthesis once the seedling has emerged from the soil.
Conclusion:
Together, the cotyledons, radicle, and plumule form the essential parts of the seed that ensure the survival and growth of the plant during its early stages of development.
