Question

Which part of the ovule stores reserve food materials?

• A. Nucellus
• B. Integument
• C. Placenta
• D. Funicle

Answer 1

The Correct Option is A

To determine which part of the ovule stores reserve food materials, we need to explore the functions and features of each of the provided options: Nucellus, Integument, Placenta, and Funicle.

• Nucellus: This is the central part of the ovule composed of parenchymatous cells. It is rich in nutrients and acts as a food reserve, providing nourishment to the developing embryo sac and, consequently, the embryo.
• Integument: This is the outer protective layer of the ovule. It develops into the seed coat after fertilization. Its primary role is protection, not food storage.
• Placenta: This is the region in the ovary where ovules are attached. It facilitates the supply of nutrients from the parent plant to the ovule, but it is not responsible for storing food.
• Funicle: This is the stalk that attaches the ovule to the placenta. It acts like a conduit for nutrients and is not involved in the storage of reserve food materials.

Based on the functions and roles described above, the Nucellus is the part of the ovule that stores reserve food materials.

Thus, the correct answer is Nucellus.
