📖 Comprehensive Study Notes Summary
### Cell Structure and Function
A cell is the smallest structural and functional unit of an organism. According to the **Cell Theory**:
1. All living things are composed of one or more cells.
2. The cell is the basic unit of life.
3. All cells arise from pre-existing cells through division.
#### Comparison: Plant vs Animal Cells
- **Cell Wall**: Present in plant cells (made of cellulose); absent in animal cells.
- **Chloroplasts**: Present in photosynthetic plant cells; absent in animal cells.
- **Vacuoles**: Large central permanent vacuole in plants; small, temporary vacuoles in animals.
- **Centrioles**: Present in animal cells; absent in higher plant cells.
#### Levels of Organization
Organelle -> Cell -> Tissue -> Organ -> Organ System -> Organism.
