Study Notes
Specialized Cells
- Cells in organisms are not all identical
- Multicellular organisms are like cities, with different parts having different functions
- Specialized cells have specific functions (e.g., energy production, transportation, waste disposal)
- Cells in multicellular organisms perform specific functions instead of trying to do everything
- Specialized cells have different structures from each other
- Example: Goblet cells in trachea produce mucus, and cilia move mucus to remove dirt
Cell Specialization
- Cells adapt to their specific function
- Structure of cells changes to suit function
- Organelles vary in number and type based on function
- Cell specialization is a change in form and function
Examples of Specialized Animal Cells
- Red blood cells: Contain hemoglobin to carry oxygen, smooth shape for easy passage through blood vessels
- Muscle cells: Arranged in bundles called muscle fibers, contract to cause movement
- Fat cells: Large vacuoles for storing fat, store chemical energy
- Nerve cells: Long, thin with branches for conducting electrical impulses
Examples of specialized Plant Cells
- Photosynthetic cells: Contain chloroplasts for collecting sunlight and making sugar
- Storage cells: Contain structures to store starch for energy
- Epidermal cells: Hair on young roots for absorbing water
- Guard cells: Control water loss in leaves
Cell Theory
- Every cell comes from a pre-existing cell
- Cells are the basic units of life
- Single fertilized egg develops into a complex organism
Similarities between plant and animal cells
- Both perform specialized functions
- Both have cells carrying out tasks vital to the organism
- Cell specialization occurs in both animal and plant cells
