Question

Tapetal cells of stamens are

• A. Diploid uninucleate
• B. Tetraploid binucleate
• C. Hexaploid tetranucleate
• D. Polyploid multinucleate

Answer 1

The correct option is D Polyploid multinucleate

The tapetum is a layer of nutritive cells found within the sporangium, particularly within the anther of flowering plants.
Tapetum is important for the development of pollen grains. The cells are usually bigger and normally have more than one nucleus per cell. As the sporogenous cells undergo mitosis, the nuclei of tapetal cells also divide. Sometimes, this mitosis is not normal due to which many cells of mature tapetum become multinucleate.

So, the correct answer is 'Polyploid multinucleate'
