Understanding Seed Structure
Seeds are vital to the life cycle of plants, and they possess different parts that serve specific functions. One of the key components of a seed is responsible for storing food, which is crucial for the development of a new plant.
What is a Cotyledon?
- The cotyledon is the part of the seed that stores nutrients and food reserves.
- These nutrients are essential for the seedling’s initial growth after germination.
Function of Cotyledons
- Energy Source: Cotyledons provide energy to the developing embryo until it can perform photosynthesis.
- Nutrient Supply: They contain starches, proteins, and fats, which are broken down and absorbed by the growing plant.
Other Parts of the Seed
- Plumule: This is the part of the seed that will develop into the shoot and eventually grow into leaves.
- Shoot: The shoot itself is the stem and leaves that will emerge above ground once the seed germinates.
- Root: The root anchors the plant and absorbs water and nutrients from the soil, but it does not store food.
Conclusion
Thus, the correct answer to the question about which part of the seed stores food is indeed the cotyledon (option D). Understanding the roles of different seed parts helps in grasping how plants grow and thrive from a tiny seed into a full-grown plant.

The cotyledon is the part of the seed that stores food. It acts as the initial food source for the developing seedling before it can begin to photosynthesize on its own. The other parts of the seed, such as the plumule (which develops into the shoot), the root, and the shoot, all play roles in growth and development, but it is the cotyledon that stores nutrients necessary for early growth.
