Question

Which one of the following layer of the anther wall helps in its dehiscence?

• A. Epidermis
• B. Middle layer
• C. Endothecium
• D. Tapetum

Answer 1

The correct option is C Endothecium

• The anther wall is differentiated into 4 layers. The epidermis is the outermost layer that is protective in function.
• The endothecium lies beneath the epidermis and is usually single-layered. The cells of the endothecium are uninucleated and vacuolated. These cells become radially elongated and undergo maximum development for the dehiscence of anthers.
• There are 1-3 middle layers that are rich in reserve food material such as starch.
• Tapetum is the innermost layer of anther wall and is nutritive and secretory in function.

Thus, the correct answer is option C.
