Study Notes
Cellular Organisation
- All living organisms are composed of cells.
- Unicellular organisms, such as bacteria, consist of a single cell.
- Multicellular organisms, including most plants and animals, are made up of millions of interconnected cells.
- Cells are microscopic, requiring a microscope for visibility.
Functions of Cells
- Main functions of both animal and plant cells include:
- Ingestion of food: Cells take in necessary nutrients.
- Energy release: Cells utilize food to produce energy.
- Waste elimination: Cells expel byproducts and waste materials.
- Growth: Cells undergo processes to increase in size and number.
- Reproduction: Cells divide to create new cells.
Structural Differences
-
Animal Cells:
- Typically small, round, and pinkish in appearance.
- Characterized by a darker purple nucleus.
-
Plant Cells:
- Generally larger and square in shape.
- Contain numerous green circles (chloroplasts) for photosynthesis.
- Feature a notable darker green cell wall providing structure and protection.
