Cells look different because they all perform different functions in the body, and therefore are made up of different components. A brain cell, for example, performs differently than a muscle cell. Therefore, the proteins that make up the cells are different, giving each cell a unique appearance.

An animal cell contains a nucleus, cytoplasm that contains the various organelles and a cell membrane, also called a plasma membrane. The nucleus is the largest of the organelles and governs cell activity. It also contains chromosomes, made up of tiny strands of DNA that replicate when the cell divi

The main difference between plant and human cells is that plant cells have a cell wall as well as a cell membrane and that some plant cells have chlorophyll. Another difference is that while there are several types of cells in the human body, there are only three types of plant cells. Rather than be

Plant and animal cells differ in terms of shape, internal arrangements and metabolism. Animal cells have less well-defined shapes than plant cells. The two cell types have different organelles, and the metabolisms of plant cells produce nutrients rather than consume them.

There are several key differences between plant and animal cells, such as cell wall structure, presence or absence of plastids, lysosomes and centrioles and shape of vacuoles. These characteristics are the primary and most distinct differences between plant and animal cells. However, they only exist

The proteome, which is the assortment of proteins found in a single cell in a specific environment, varies greatly from one type of cell to another, according to Annenberg Learner. For example, a typical bacterial cell contains more than 4,000 proteins, while mammals, including humans, require upwar
