Answer to Question #343518 in Cell Biology for arinah

Question

recall the structures found in animal and plant cells including algal cells

Answer 1

Each eukaryotic cell has a plasma membrane, cytoplasm, endoplasmatic reticulum, Golgi apparatus, a nucleus, ribosomes, mitochondria, peroxisomes, cytosceleton and in some, vacuoles; however, there are some striking differences between animal and plant cells. While both animal and plant cells have microtubule organizing centers (MTOCs), animal cells also have centrioles associated with the MTOC: a complex called the centrosome. Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

Algal cells are eukaryotic and contain three types of double-membrane-bound organelles: the nucleus, the chloroplast, and the mitochondrion. In most algal cells there is only a single nucleus, although some cells are multinucleate. Algal cells also have several single-membrane-bound organelles, including the endoplasmic reticulum, Golgi apparatus, lysosomes, peroxisomes, contractile or noncontractile vacuoles, and, in some, ejectile organelles. Several classes of algae in the division Chromophyta have mucous organelles that secrete slime. The nonmembrane-bound organelles of algae include the ribosomes, pyrenoids, microtubules, and microfilaments. The cell walls of many, but not all, algae contain cellulose.
