There are two major groups that cells can be grouped into to. These are eukaryotic and prokaryotic cells. All eukaryotic cells contain a plasma membrane, as well as cytoplasm and organelles such as mitochondria, rough endoplasmic reticulum (ER), Golgi apparatus, smooth ER, ribosomes, a nucleus which is surrounded by a double membrane known as the nuclear envelope, and secretory vesicles. There are some eukaryotic cells which contain more organelles as well as theses. Some eukaryotic cells, specifically in plants, have chloroplasts. Chloroplasts are organelles that contain stacks of granum known as thylakoid stacks. The granum contains chlorophyll, and the first stage of photosynthesis occurs here. Some eukaryotic cells contain centrioles, which are strands of protein involved in the process of mitosis and meiosis. Pant cells have a cell wall made from cellulose. This prevents the cell from bursting from too much water uptake via osmosis. Fungi do not have chloroplasts. They do have a cell wall like plant cells, but whereas the cell walls in the plant cells are made from cellulose, the cell wall in a fungal cell is made from chitin. This is a polymer made from N-acetylglucosamine. Prokaryote is the name of a kingdom for organisms, and all bacteria fall into this kingdom. The prokaryote kingdom is enormous, and prokaryotes are found in every known habitat on the planet. Bacteria are very useful, they can be used in biomedical sciences to help develop medicines, and…
