Fertilization in gymnosperms involves a process called porogamy, where the pollen tube grows towards the ovule.
Here's a breakdown of the fertilization process in gymnosperms:
| Step | Description |
|---|---|
| 1 | Pollen Arrival: Pollen grains land on the female cone. |
| 2 | Tube Cell Development: When the pollen lands on the female cone, tube cells develop. |
| 3 | Migration Towards Ovule: The pollen tube cell migrates towards the ovule through the micropyle. This process is known as porogamy. |
| 4 | Fertilization: After the pollen tube reaches the ovule, fertilization takes place. |
| 5 | Zygote Formation: Fertilization results in the formation of a diploid zygote. |
In summary, fertilization in gymnosperms involves the pollen grain landing on the female cone, development and migration of the pollen tube towards the ovule through the micropyle (porogamy), and finally, the fusion of gametes to form a diploid zygote.
