Worked practice questions

Which anther wall layer nourishes the developing pollen grains?

  1. Tapetum
  2. Endothecium
  3. Epidermis
  4. Middle layers
Show answer and solution

Correct answer: A. Tapetum

The innermost wall layer, the tapetum, has dense multinucleate cells that feed the developing microspores.

An anther is called dithecous because each of its lobes has

  1. one theca
  2. two theca
  3. three theca
  4. four theca
Show answer and solution

Correct answer: B. two theca

Dithecous literally means two-thecate, so each of the two lobes carries two theca.

The formation of microspores from a pollen mother cell takes place by

  1. simple mitosis
  2. free nuclear mitosis
  3. multiple fission
  4. reduction division
Show answer and solution

Correct answer: D. reduction division

A pollen mother cell is diploid and divides meiotically, giving a tetrad of haploid microspores.
