Study Notes
Cell Membrane Function
- Regulates what enters and leaves the cell
- Controls the movement of materials in and out of the cell
- Acts as a barrier between the cell and its environment
Organelle Functions
- Lysosomes are responsible for breaking down waste materials in an animal cell
- Contain digestive enzymes that break down and recycle cellular waste and foreign substances
Mitochondria Function
- Generate energy for the cell through cellular respiration
- Convert glucose into ATP (adenosine triphosphate) through cellular respiration
- Often referred to as the "powerhouses" of the cell
Golgi Apparatus Function
- Receives proteins and lipids from the endoplasmic reticulum
- Modifies, sorts, and packages proteins and lipids for transport to other parts of the cell
- Plays a key role in protein synthesis and secretion
Plant vs Animal Cells
- Plant cells have a cell wall, chloroplasts, and a large vacuole, whereas animal cells do not
- Animal cells have lysosomes, whereas plant cells do not
- Plant cells are generally larger than animal cells
Cytoskeleton Function
- Provides structural support and shape to the cell
- Plays a key role in cell division, differentiation, and movement
- Composed of microtubules, microfilaments, and intermediate filaments
