Study Notes
Cell Structure
-
Cell Membrane (Plasma Membrane):
- Semi-permeable membrane that separates the cell from its environment
- Regulates what enters and leaves the cell
-
Cytoplasm:
- Jelly-like substance inside the cell membrane
- Site of many cellular activities (metabolism, protein synthesis)
-
Nucleus:
- Control center of the cell
- Contains DNA (genetic material)
-
Organelles:
- Mitochondria: generate energy for the cell
- Endoplasmic Reticulum (ER): protein synthesis and transport
- Ribosomes: protein synthesis
- Lysosomes: cell digestion and recycling
- Golgi Apparatus: protein modification and transport
Cell Types
-
Prokaryotic Cells:
- Lack true nucleus
- Typically small, simple cells (bacteria)
-
Eukaryotic Cells:
- Have true nucleus
- Typically larger, more complex cells (plants, animals, fungi)
6th Grade Cell Respiration
-
Cellular Respiration:
- Process by which cells generate energy from glucose
- Occurs in mitochondria
-
Aerobic Respiration:
- Requires oxygen (O2)
- Produces energy (ATP) and water (H2O) as byproducts
-
Anaerobic Respiration:
- Does not require oxygen (O2)
- Produces energy (ATP) and lactic acid as byproducts
Cell Structure
- Cell membrane is semi-permeable, regulating what enters and leaves the cell.
- Cytoplasm is a jelly-like substance inside the cell membrane, where many cellular activities occur.
- The nucleus is the control center of the cell, containing DNA (genetic material).
- Mitochondria generate energy for the cell through cellular respiration.
- Endoplasmic Reticulum (ER) is responsible for protein synthesis and transport.
- Ribosomes are responsible for protein synthesis.
- Lysosomes facilitate cell digestion and recycling.
- Golgi Apparatus modifies and transports proteins.
