WebSep 7, 2024 · The eukaryotic cells types are generally found in animals, plants, algae, and fungi. For the purpose of this article, the primary focus will be the structure and histology of the animal cell. The major differences between animal and plant cells will be explored as well. As previously stated, the fundamental components of a cell are its organelles. WebMicrofilaments are the thinnest part of the cytoskeleton, and are made of actin [a highly-conserved protein that is actually the most abundant protein in most eukaryotic cells]. Actin is both flexible and strong, making it a useful protein in cell movement.

"WebCollectively, this network of protein fibers is known as the cytoskeleton. There are three types of fibers within the cytoskeleton: microfilaments, intermediate filaments, and microtubules ( Figure ). Here, we will examine each. Microfilaments thicken the cortex around the inner edge of a cell; like rubber bands, they resist tension. " - Cytoskeleton of prokaryotes
