Question

Replum is a

• A. False placenta
• B. False septum
• C. False ovule
• D. False thalamus

Answer 1

The correct option is B False septum

Replum is the frame-like placenta, across which the septum stretches, from which the valves of a capsule or other dehiscent fruit fall away in dehiscence, as in Cruciferae, certain Papaveraceae, Mimosa, etc. sometimes incorrectly applied to the septum. The fruit of Cruciferae is a peculiar kind of capsule named as siliqua.
It opens by two valves, which are the modified carpels, leaving the seeds attached to a framework made up of the placenta and tissue from the junction between the valves (replum).
In Cruciferae, ovary is unilocular but becomes bilocular due to development of false septum called as replum. So, replum is false septum and not false ovule, false thalamus or placenta.

Thus, the correct answer is option B.
