Cell Function
Cell Membrane:
- Outer layer
- Support, protection,
- controls movement of materials going in and out,
- barrier between cell and it environment,
- Maintains homeostasis.
Nucleus:
- Large, oval
- Holds DNA
- Controls cell activities
- Contains the hereditary material of the cell
Nuclear membrane:
- Surrounds nucleus
- Double membrane
- Selectively permeable
Cytoplasm:
- Clear, thick, jellylike material
- Organelles found inside cell membrane
- Contains the cytoskeleton fibers
- Supports and protects cell organelle
Endoplasmic reticulum:
- network of tubes and membranes
- smooth w/o ribosomes
- rough with embedded ribosomes
- connects to nuclear envelope and cell membrane
- Carries materials through cell
- Aids in making proteins
