Nucellus
The question asks which part of an ovule contains reserve food, and we need to identify the correct option based on our understanding of plant biology.
Let's analyze each option to find the correct answer:
- Integument: This is the outer covering of the ovule. It does not store reserve food. Instead, it develops into the seed coat after fertilization.
- Nucellus: This is the mass of cells in the ovule, where reserve food is stored. It serves as nourishment for the developing embryo before fertilization and is the correct answer.
- Chalaza: This is the basal part of an ovule, where the integument and nucellus are attached. It does not store food.
- Funicle: This is the stalk that attaches the ovule to the placenta inside the ovary. It is not involved in food storage.
Thus, the nucellus is the part of the ovule that possesses reserve food, making it the correct choice.
In summary, the correct option is Nucellus, as it is responsible for storing food within the ovule. Understanding these parts of the ovule helps us grasp their functions in plant reproduction.
