Animal cells aren't all shaped the same way; the shape of a specific animal cell depends on its function and where it is in the body. Unlike plant cells, animal cells do not have rigid cell walls that limit them to a rectangular shape.Know More
Many animal cells appear roughly spherical when viewed through a microscope. Neurons tend to have long protrusions sticking out from a central cell body. Adipose cells, which store fat in the body, tend to be almost perfectly spherical when filled, and become flatter when empty. Muscle cells are elongated, and they can stretch and contract when the organism moves.
The epithelial cells that make up the outer layer of skin tend to be flat and devoid of many of the organelles present in other cells, while the underlying layers of skin have cells that line up in columns or rows. Red blood cells are rounded, with a visible concavity in the center. Immune cells change their shape to squeeze into tight spaces between other cells and to stretch around invading bacteria, viruses and particles, surrounding and neutralizing them. Egg cells are typically large and round, while sperm cells have a rounded head and a tail that facilitates movement.Learn more about Cells
A lysosome is an organelle in an animal cell that contains enzymes to break down outside materials that enter the cell, as well as obsolete cell material. The lysosome acts as the digestive system for the cell, consuming proteins, carbohydrates and lipids.Full Answer >
Animal cells function in a variety of ways, depending on the type of cell they are, but common cells perform functions such as digestion, support and nerve transmission. There are a number of different types of cells in every animal, though most animals have similar types of cells. Cell function influences the shape, size and character of the cells in animal bodies.Full Answer >
The function of the nuclear membrane in an animal cell is to hold the DNA inside the nucleus in order to protect it from surrounding substances. The nuclear membrane also regulates which substances can enter or exit the nucleus.Full Answer >
Animal cells are eukaryotic cells, or cells that contain a membrane-bound nucleus. The nucleus holds the DNA of the cell that provides the cell with instructions for life.Full Answer >
