What is porogamy?

Options

• Entry of the pollen tube through the synergid cells

• Entry of the pollen tube through the funicle or integuments

• Entry of the pollen tube through the micropyle of the ovule

Answer 1

Porogamy is the most common type of pollen tube entry into the ovule, where the tube enters through the micropyle (the small opening at the micropylar end of the ovule). This route is used by plants such as pea, sunflower, and lily.
