WEBSep 20, 2024 — cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature.
Cell Structure - Biology Dictionary
WEBApr 1, 2021 — All eukaryotic cells consist of three basic parts. These are the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the outside of the cell, the nucleus is found in the middle of the cell, and the cytoplasm fills the gap between the two.
Cell Parts and Functions - Biology Dictionary
WEBMar 31, 2021 — Usually, a cell has a single nucleus that contains all of its DNA molecules, but some (such as skeletal muscle cells) have more than one nucleus. The nucleus protects the cell’s DNA while controlling all other cellular activities, such as cell division, growth, protein production, and cell death.
