Here is the corrected list of cell structures with their respective functions or definitions:
- Cytoplasm: Everything between the nuclear membrane and the cell membrane.
- Centrioles: Structure that organizes the motion of chromosomes during cell division.
- Lysosome: Sac filled with digestive chemicals that break down waste and cellular debris.
- Mitochondria: Structures that convert nutrients into energy (ATP) through cellular respiration.
- Cell membrane: Membrane that surrounds and protects the cell.
- Endoplasmic reticulum: Passageways where chemicals are synthesized and transported; includes rough (with ribosomes) and smooth (without ribosomes) types.
- Vacuole: Sac that stores water, nutrients, or waste products; larger in plant cells.
- Nucleus: Structure that contains DNA and regulates gene expression; also responsible for controlling cellular activities.
- Cytoskeleton: Tubules and filaments that give the cell its shape and facilitate movement.
- Nuclear membrane: Membrane that protects the nucleus and regulates what enters and exits.
- Golgi apparatus: Stack of membranes that packages chemicals and prepares them for transport or secretion.
- Ribosome: Small structure that synthesizes proteins; can be free-floating or attached to the endoplasmic reticulum.
- Vesicle: Package created by the Golgi apparatus or endoplasmic reticulum that transports materials within the cell.
- Nucleolus: Structure within the nucleus that manufactures ribosomes.
This corrected list accurately pairs each cellular structure with its proper function or role.
