Arrange the following in the correct developmental sequence related to microsporogenesis :

A. Microspore tetrads
B. Sporogenous tissue
C. Pollen grains
D. Pollen mother cells

Choose the correct answer from the options given below :

The correct developmental sequence for microsporogenesis is B, D, A, C.

Step 1 – Sporogenous tissue (B): The innermost layer of the anther contains the sporogenous tissue, which gives rise to the cells that will undergo meiosis.

Step 2 – Pollen mother cells (D): Cells within the sporogenous tissue differentiate into pollen mother cells (also called microspore mother cells). These are diploid cells that will be the precursors of microspores.

Step 3 – Microspore tetrads (A): Each pollen mother cell undergoes meiosis, producing a tetrad of four haploid microspores. The tetrad remains temporarily attached.

Step 4 – Pollen grains (C): The microspores are released from the tetrad, mature, and develop into functional pollen grains, the male gametophytes ready for pollination.
