Syngamy

Definition

Syngamy is the fusion of two gametes to form a zygote, initiating the development of a new organism. It is a critical process in sexual reproduction among plants and other organisms.

5 Must Know Facts For Your Next Test

1. Syngamy occurs in the life cycles of both lower and higher plants.
2. This process leads to the formation of a diploid zygote from haploid gametes.
3. Syngamy is essential for genetic variation and biodiversity in plant populations.
4. It typically occurs after pollination and fertilization in flowering plants.
5. Some plants have mechanisms to ensure syngamy happens between genetically diverse individuals.

Gamete: A reproductive cell (sperm or egg) that fuses with another during syngamy.

Zygote:

The initial cell formed when two gametes merge during syngamy; it develops into a new organism.

Pollination: The transfer of pollen from the male structures to female structures of plants, preceding fertilization and syngamy.
