Fertilisation is the union of haploid gametes to form a diploid zygote, initiating embryonic development. It occurs across various kingdoms, including animals, plants and fungi, though the mechanisms differ among groups.
In animals, fertilisation can be external or internal. External fertilisation takes place when gametes are released
The general sequence involves recognition between sperm and egg, penetration of protective layers by the sperm
In plants, fertilisation usually involves pollen delivering sperm cells to the ovule via a pollen tube. In
Fertilisation is central to sexual reproduction and contributes to genetic variation, enhancing adaptability. Errors in gamete
