slavikrds [6]

<h2>Apical complex</h2>

Explanation:

A group of cytoskeletal structures and related layer limited organelles found at the foremost finish of grown-up commit intracellular protozoan parasites in the phylum Apicomplexa. The apical complex is engaged with connection to and infiltration of the host cell and in parasite multiplication.
Apicomplexans : Ciliates are pretty cool, but they're not the only group of alveolates out there. Next, we've got the apicomplexans. This group is characterized by an asymmetrical collection of alveoli at one end of the cell, which is called the apical complex.
the apical complex has shaped the way it is because it helps the cell latch onto and infects other cells.That's right, apicomplexans are parasitic. There are 4,000 known species of apicomplexans, all of them parasitic, and some of them pretty nasty.

Cells lining the small intestine are specialized for absorption of nutrients. their plasma membrane has microvillus (plural: microvilli) which increase cell surface area. These are cellular membranes that are microscopic in nature that increases the surface area of the cell for diffusion and minimize increase in volume.
