All of the above.

Answer 2

T.S of the anther before meiosis will show the presence of Pollen mother cells.

EXPLANATION

• The anther is the male reproductive organ of the angiosperms.
• In a dithecous anther, two microsporangia are present in each lobe of the anther.
• These microsporangia, also known as pollen mother cells undergo meiotic divisions to form pollen grains.
• The pollen mother cells are diploid cells that undergo meiotic cell division to form four haploid pollen cells.
• These cells are joined by a callous wall. Therefore, this group of 4 pollen cells is also called pollen tetrad.
• This tetrad of a cell is broken by the action of the callase enzyme on the callous wall freeing the pollen cells.
• Each pollen cells grow further to become pollen grains.
• These pollen grains develop a bilayered resistance wall- an outer layer exine and an inner layer intine.

Hence, The correct answer is - Pollen mother cells.
