Question and answer
what are the compare structures and functions of different cell types
There are many types of cells. In biology class, you will usually work with plant-like cells and animal-like cells. We say animal-like because an animal type of cell could be anything from a tiny microorganism to a nerve cell in your brain. [ Plant cells are easier to identify because they have a protective structure called a cell wall made of cellulose. Plants have the wall; animals do not.
Plants also have organelles like the chloroplast (the things that make them green) or large water-filled vacuoles. We said that there are many types of cells. Cells are unique to each type of organism. Humans may have hundreds of types of cells. Some cells are used to carry oxygen (O2) through the blood (red blood cells) and others might be specific to the heart. If you look at very simple organisms, you will discover cells that have no defined nucleus (prokaryotes) and other cells that have hundreds of nuclei (multinucleated). The thing they all have in common is that they are compartments surrounded by some type of membrane. ]
