What do you call a group of cells that perform similar functions?

A:

Quick Answer

A group of cells that performs a similar function is known as a tissue. Multicellular organisms such as animals all contain differentiated cells that have adapted to perform specific functions. These differentiated cells group together to form tissues. A group of tissues that perform similar functions are known as organs.

Full Answer

As multicellular organisms develop, their cells differentiate to carry out different functions. As they differentiate into different groups, they form into tissues. In total there are four basic tissue types: connective tissue, muscle tissue, nervous tissue and epithelial tissue. All these tissue types group together to form organs and organ systems. Connective tissues support, protect and strengthen the organism. Muscle tissues are broken into three different types of muscle known as skeletal muscle, smooth muscle and cardiac muscle. All types of muscle tissue contract and relax to help organisms move and function. Nervous tissue transmits electrical and chemical signals throughout the organism. These signals allow cells to communicate with each other. Epithelial tissues form the surface of the skin of many organisms and line the cavities of organs and organ systems. Each tissue type performs specific functions in specific organisms. Their functions depend on the cell type that the tissues are comprised of and the amount of cells present.

    What functions do phospholipids have in cells?

    A:

    Phospholipids serve as a permeable barrier for the cell membrane and its internal organelles. They also provide support and serve as the site for catalytic processes. They have roles in signal transduction and are precursors for signaling processes and the synthesis of molecules.

    What is a group of cells that form from an original single cell?

    A:

    Cells arising from a single progenitor cell are called daughter cells or clones. These terms apply only to cells arising through binary fission in prokaryotes or mitosis in eukaryotic cells. In contrast, sperm and eggs, collectively called gametes, arise from a progenitor cell through a distinct process called meiosis.

    How many cells do fungi have?

    A:

    The exact number of cells in fungi isn't known, but fungi are multicellular, meaning they are made of more than one cell. Most fungi with single cells are in the yeast family and are used in baking and bread making.

    What are bundles of muscle cells called?

    A:

    Bundles of individual muscle cells are known as fascicles. They are covered by a connective tissue sheath known as the perimysium. Fascicles bundle together to form large muscle groups.
