There are 13 main parts of an animal cell: cell membrane, nucleus, nucleolus, nuclear membrane, cytoplasm, endoplasmic reticulum, Golgi apparatus, ribosomes, mitochondria, centrioles, cytoskeleton, vacuoles, and vesicles.
Animal cells have structures called lysosomes (which are basically organelles containing an extremely acidic fluid to break down objects) and centrosomes (used in cell reproduction). Plant cells have neither of these.

Cell parts and their functions (video) | Khan Academy. Google Classroom. Microsoft Teams. About. Transcript. Within cells, special structures are responsible for particular functions. For example, mitochondria help release energy that the cell can use for other tasks, and the nucleus contains the genetic information.
8 de mar. de 2022 · Explainer: Prokaryotes and Eukaryotes. Over time, some cells became more complex. Called eukaryotes (Yu-KAER-ee-oats), these now make up animals, plants and fungi. Some one-celled organisms, such as yeasts, also are eukaryotes. These cells are all like single-family houses — with walls and doors making up separate rooms.
