6.12AB, 7.12CD Prokaryote/Eukaryote, Organization Levels, & Cell Organelles
Term | Definition |
---|---|
EUKARYOTIC CELL | Cell with nucleus & membrane-bound organelles. |
PROKARYOTIC CELL | Cell lacking a nucleus or any other membrane-enclosed organelle. |
CELL MEMBRANE | Protective layer that surrounds a cell or an organelle. |
NUCLEUS | Membrane-bound structure in eukaryotic cells that contains DNA. |
DNA | Contains information that forms the hereditary material of all cells. |
CELL | Basic structural and functional unit of living organisms. |
TISSUE | Large mass of similar cells that make up a part of an organism and perform the same specific function. |
ORGAN | Large collection of similar tissue that make up a part of an organism and performs a specific and specialized function of the body. |
ORGAN SYSTEM | Composed of several organs working together to perform specific and vital functions. |
ORGANISM | Individual form of life that is capable of growing, taking in nutrients, and usually reproducing (organ systems working together); self-contained living thing. |
ORGANELLE | Tiny cell structure that carries out a specific function within the cell. |
POPULATION | Group of individuals of the same species that live in the same area. |
Cytoplasm | Jellylike & fluid material that makes up much of a cell inside the cell membrane, surrounds the nucleus in eukaryotic cells, & in which the organelles are suspended; cyto = hollow |
Mitochondrion | Organelle in the cytoplasm of eukaryotic cells that functions in energy production - power factory of the cell. |
Vacuole | Organelle that stores water & nutrients in both plant & animal cells; 1 large central unit in plant cells, but many small units in animal cells. |
Chloroplast | Green organelle in plant cells that converts light energy into chemical energy (Photosynthesis); chlor = green; plast = small particle |
Cell Wall | Rigid structure that surrounds the cell membrane of a plant cell to give it support & protection. |
