Question

In porogamy, the pollen tube enters the ovule through.

• A. Funicle
• B. Chalaza
• C. Micropyle
• D. Integuments

Answer 1

Answer: (C)

Micropyle

Pollen tube eventually reaches the micropyle 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 in 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 C.
