Question

In porogamy, pollen tube enters ovules through

• A. Micropyle
• B. Chalazal end
• C. Ovary wall
• D. Integument

Answer 1

The correct option is A Micropyle

Pollen tube eventually reaches the micropylar end of an ovule and for this purpose, it may follow one of the following three routes:

1. Porogamy- When the pollen tube enters the ovule through micropyle. It is common for most of the angiosperms.

2. Mesogamy- When the pollen tube enters through the integuments or through funiculus.

3. Chalazogamy- When the pollen tube enters through the chalazal tissues.

So, the correct answer is A.
