Cell Organelles
| Organelle | Function |
|---|---|
Nucleus
|
Contains DNA, controls cell activities |
Mitochondria
|
Powerhouse of cell, produces ATP |
Ribosomes
|
Protein synthesis |
Endoplasmic Reticulum
|
Protein and lipid transport |
Golgi Apparatus
|
Packages and ships proteins |
Lysosomes
|
Breaks down waste materials |
Cell Membrane
|
Controls what enters/exits cell |
Cytoplasm
|
Gel-like substance filling cell |
Plant Cell Only
| Organelle | Function |
|---|---|
Cell Wall
|
Rigid structure for support |
Chloroplasts
|
Photosynthesis |
Vacuole
|
Storage of water and nutrients |
Key Processes
Mitosis
Cell division (1 cell → 2 identical cells)
Meiosis
Gamete formation (1 cell → 4 unique cells)
Photosynthesis
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Cellular Respiration
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
💡 Pro Tip:
Remember: Animal cells have centrioles, plant cells have cell walls!
