Cell Structures and Functions in Organisms
- Living organisms are composed of cells, the basic unit of life. Animal cells consist of the nucleus containing DNA, the cell membrane controlling what enters and exits, and the cell cytoplasm where chemical reactions like respiration occur in structures called mitochondria. Plant cells, in addition to these components, have a cell wall for support, chloroplasts containing chlorophyll for photosynthesis, and vacuoles storing cell sap for support and sugar storage.
- Specialized cells like red blood cells lack a nucleus to maximize oxygen absorption, nerve cells have dendrites for communication and axons for message transmission, and white blood cells fight infections through phagocytosis and antibody production, identifiable by their lobed nucleus and flexible cytoplasm.
