Question

The funiculus is the:

a. ovule-bearing region of the ovary wall.
b. stalk of the ovule.
c. wall of the megasporangium.
d. inner integument.
e. interior of the nucellus.

Answer 1

The funiculus is the stalk of the ovule that connects the ovule to the ovary wall within the carpel. It is part of the internal structure of the ovary where the megasporangium, protected by integuments, is located.

Step-by-step explanation:

The funiculus is a term used to describe b. the stalk of the ovule. This structure connects the ovule to the ovary wall within the carpel of a flowering plant. The ovary contains the ovules where megasporangium is located. The ovule is protected by two layers called integuments which later develop into the seed coat after fertilization. The ovule wall becomes part of the fruit. Importantly, the integuments enclose the megasporangium but leave an opening known as the micropyle, which is crucial for allowing the pollen tube to enter the female gametophyte for the process of fertilization.

Answer 2

The funiculus is the stalk that connects the ovule to the ovary wall, serving as a conduit for nutrients (option b).

Step-by-step explanation:

The question pertains to the reproductive structures within the ovary of a flowering plant. Specifically, it asks for the definition of the funiculus. The funiculus is, in fact, the stalk that connects the ovule to the ovary wall. This stalk is crucial as it provides the pathway for nutrient transfer between the plant's tissue and the developing ovule. During the development of the seed, the funiculus sometimes remains as a visible scar, known as the hilum.

Therefore, the correct answer to the question is that the funiculus is b. the stalk of the ovule.
