Apicomplexa is a type of protozoa that include parasitic organisms that exist only within a host. Apicomplexans contain a large volume of single-celled eukaryotic organisms. The apicomplexan uses its organelle for penetrating into the host cell and live inside the cavities or the cells of almost every kind of animal, including other apicomplexans. The parasites are resistant and have better access to nutrients inside cells, where they can grow and reproduce. The most commonly known...
Apicomplexa is a type of protozoa that include parasitic organisms that exist only within a host. Apicomplexans contain a large volume of single-celled eukaryotic organisms. The apicomplexan uses its organelle for penetrating into the host cell and live inside the cavities or the cells of almost every kind of animal, including other apicomplexans. The parasites are resistant and have better access to nutrients inside cells, where they can grow and reproduce. The most commonly known apicomplexan is the agent that causes malaria in human hosts. Apicomplexans get their food by absorbing dissolved food that has been ingested by the host or directly feed on the host’s cytoplasm and body fluids (such as blood). Apicomplexans can reproduce sexually or asexually in its life cycle. Sexual reproduction produces spores that are spread in the environment, and asexual reproduction is by multiple fission or binary cell division.
Amoebae is a form of protozoa that can change its shape. This type of protozoa is usually found in water and soil, and it feeds on organic material or absorbing dissolved nutrients through vessels. The amoeba protozoa simply split itself in two when it reproduces. ‘They can create extensions of their body wall called pseudopodia that help them capture prey or simply churn up their insides to distribute nutrients.’ Amoebas can reach a maximum size of 2 mm in diameters.
