The eukaryotic kingdom known known as Chromista is composed of single celled organisms among which of all the algae containing chlorophyll a and c. Most of the species belonging to this group are also photosynthetic.
Due to the vast number of species, some Chromistas have an asexual reproduction, whereas other reproduce sexually.
Asexual reproduction is achieved by the process of cellular division known as mitosis in which a parent cell divides into two identical daughter cells.
Sexual reproduction occurs through flagellated zoospores. Male gamets are produced by the antheridia, the male sex organ of algae, ferns, fungi etc. The haploid female gamets are produced through mitosis in oogonia. The joining of two gamets is called syngamy.
