Question
In gynogenesis, which part of the plant is often used as the source for isolating macrospores?
- a. Roots
- b. Ovary
- c. Anthers
- d. Leaves
Solution
In gynogenesis, the correct answer is b. Ovary.
Explanation
Gynogenesis is a form of asexual reproduction in which seeds or embryos develop from an unfertilized egg. The process typically involves the use of a specific plant part where gametes are produced. In flowering plants, the ovary is the structure that contains the ovules, which eventually develop into seeds after fertilization. Since gynogenesis does not require fertilization, researchers often focus on the ovary for isolating macrospores, as it can provide the necessary gametic material.
Other plant parts like roots, anthers, and leaves do not contain the same reproductive structures needed for gynogenetic processes. Thus, when considering the source for isolating macrospores in gynogenesis, the ovary is the appropriate choice.
