Intine
The part of the pollen grain that develops into the pollen tube is known as the intine. The intine is the inner layer of the pollen grain, located beneath the outer layer called the exine.
Pollen Tube Development
- After pollination, the pollen grain lands on the stigma of the flower and absorbs water, causing it to germinate.
- The germ pore, which is a pore in the exine, allows the pollen tube to protrude out from the pollen grain.
- The intine grows out of the pollen grain and forms the pollen tube, which elongates and penetrates the style of the flower.
- The pollen tube serves as a conduit for the male gametes to reach the ovule and fertilize the egg cell.
Function of the Pollen Tube
- The pollen tube provides a pathway for the male gametes to travel from the pollen grain to the ovule.
- It delivers the sperm cells to the embryo sac within the ovule, where fertilization takes place.
- The growth and elongation of the pollen tube are crucial for successful pollination and fertilization in plants.
In conclusion, the intine of the pollen grain develops into the pollen tube, which plays a vital role in the reproductive process of flowering plants.
