Question

Which of the following is an example of bisporic embryo sac?

• A. Peperomia
• B. Polygonum
• C. Allium
• D. None of the above

Answer 1

The correct option is C

Allium

The correct option is C.

Explanation for Correct option:

1. In bisporic embryo sacs, the process of meiosis produces only two megaspores. Each megaspore contains two haploid nuclei.
2. Due to the absence of cytokinesis and cell plate formation following the second meiotic division.
3. The megaspore nearest the micropyle then undergoes programmed cell death, leaving a single functional megaspore with two haploid nuclei.
4. It is also known as Allium-type embryo sac.

Final answer:

An example of bisporic embryo sac is Allium
