- Cell membrane
- separates cell from surrounding environment
- Cell theory
-
1) All living things are made up of cells.2) Cells carry out life functions.3) Cells arise from other cells.
- Cell wall
- present only in plant cells, provides shape and support
- Centriole
- cylindrical organelles involved in cell division
- Cytoplasm
- watery material within cell that cushions organelles and is where many chemical reactions take place
- Endoplasmic reticulum
- system of fluid-filled canals that serve as transport paths in the cell
- Eukaryotic
- cells containing organelles
- Golgi Bodies
- stacks of flattened membrane sacs used for processing, packaging, and storing materials in the cell
- Lysosomes
- small, saclike structures containing strong digestive enzymes in the cell
- Microfilaments
- long, solid, threadlike strands in SOME cells involved in movement
- Microtubules
- long, hollow, cylindrical organelles that serve as a 'skeleton' for the cell
- Mitochondria
-
round organelles that release energy from food moleculesMITOCHONDRIA = RESPIRATION = ATP!!
- Nucleus
- control center of cell
- Prokaryotic
- cells lacking any internal serparation
- Ribosomes
- sites of protein synthesis in a cell
- Selectively permeable
- some substances can pass through the membrane freely, others cannot
