A. The most vital event of sexual reproduction is perhaps the fusion of gametes. This process called syngamy results in the formation of a diploid zygote. The term fertilisation is also often used for this process. The terms syngamy and fertilisation are frequently used though , interchangeably.
B. An organism can develop from the female gametes, without fertilisation. This process is called parthenogenesis. It is seen in certain organisms like rotifers, aphids and honey bees, lizard. Parthenogenesis is a form of reproduction in which an egg can develop into an embryo without being fertilized by a sperm.
C. In some algae the two gametes are so similar in appearance that it is not possible to categorise them into male and female gametes.They are hence called homogametes (isogametes).Example : Isogametes of Cladophora (an alga).
D. In a majority of sexually reproducing organisms the gametes produced are of two morphologically distinct types (heterogametes).Example: Heterogametes of Fucus (an alga).
