The properties that the earliest proto-cells hypothesized to have in common with modern-day cellular organisms and mention the properties of modern-day cellular organisms that are hypothesized to have been absent in the earliest proto-cells. Introduction: The evolution of cell membrane plays a very important role in the adaptation of modern cellular organisms in the varying environment. It keeps useful cellular secretions intact, maintains chemically distinct intracellular components, and provides protection from parasitic attack.

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.
