Give an example for a cell which proves that the shape and size of the cell is related to the specific function they perform.
Answers
Answer:
I explain it as an example of evolution. The unicellular organisms that are closest to multicellular organisms such as choanoflagellates have two forms, a more sessile for that feeds on adjacent bacteria and an ameboid form that can move to a better environment. The emergence of multicellularity provided some advantages as cells remained associated with each other. A sheet of adjacent cells could become a round ball and seal up an inner environment. Early multicellular organisms with two cell phenotypes likely did better because the motile form could specialize for communication, maintenance or specialized synthesis. Selection likely favors certain specializations. For example, organisms above a certain size need a distribution system of oxygen and nutrients. Internal cells that could use their myosin motor proteins to contract could specialize to distribute hemolymph or blood by beating. Each specialization that produces an advantage was likely sustained by the survival of that organism. The result of that process is the variety of cell types and species that we see today.
Explanation:
The shape and size of the cells are related to the specific function they perform. some cells like amoeba have changing shapes. in some cases the cell shape could be more or less fixed and peculiar for a particular type of cell for example nerve cells have a typical shape.
