Question

In a particular plant with bilobed dithecous anther, there were 50 Pollen Mother Cells. Only 25% could develop their pollen tubes.

Calculate the number of pollen grains that would proceed for fertilisation.

Answer 1

Each Pollen Mother Cell (PMC) undergoes meiosis to produce 4 pollen grains.

Total pollen grains produced = 50 × 4 = 200

Only 25% of these pollen grains successfully germinate and develop pollen tubes.

Calculation: 200 × 0.25 = 50

50 pollen grains will proceed for fertilisation.
