How many types of cells are found in a living organism?
Cells are the basic unit of life. Plants and animals have different types of cells. Similar processes occur in both types of cells.
Plant and Animal Cells: A Comparison
Cell: The basic unit of life, composed of a membrane, cytoplasm, and genetic material. Plant Cell: A type of eukaryotic cell that contains a large central vacuole, chloroplasts, and a rigid cell wall. Animal Cell: A type of eukaryotic cell that lacks a cell wall and chloroplasts, but contains lysosomes, mitochondria, and other organelles.
Concepts:
Plant cells can be as much as 15 times bigger than animal cells. Animals are able to move around because their cells contain specialized structures called cytoskeletons. Plant cells contain chloroplasts, which are used for photosynthesis to produce energy from sunlight.
