Solitary cells in biology
WebThe feeding stage consists of solitary cells that feed and divide mitotically as individuals. When food is scarce, the cells form an aggregate (“slug”) that functions as a unit. Each cell retains its identity in the aggregate. The dominant stage in a cellular slime mold is the haploid stage. Most cellular slime molds lack flagellated stages. WebProtozoa do not have a cell wall and therefore can have a variety of shapes. Nevertheless, some of the protozoans have a pliant layer, a pellicle, or a stiff shell outside the cell membrane. Protozoa vary in size and shape. Their sizes range from 10 to 55 micrometers, but they can be as large as 1 mm.
