Do animals have one or many cells? Animals include invertebrates like insects, and vertebrates like mammals and birds. Six important aspects of animals are: 1. Animals are multicellular, which means they have many cells.
What are the 13 animal cells?
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.
Are there cells in animals?
Animals are multicellular organisms, and as such, their body is comprised of several cells (about trillions of cells). A group of cells performing a specific function is called a tissue.

What does a ribosome do?
Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins.
What is a cell?
In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. Parts of a cell. A cell is surrounded by a membrane, which has receptors on the surface.
Do animal cells have a cell wall?
