The mechanism of secondary endosymbiosis takes place by the phagocytosis of the red algae by the unicellular eukaryotes to produce the higher organisms. The red algae have specific pigments, which are different from the chlorophyll-containing plastids. Therefore, the plastids are not present in the higher eukaryotes formed by the process of endosymbiosis. The new species have various pigments essential for the metabolic functions of the cell. These species do not have the plastids containing the green pigment chlorophyll.

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
