Study Notes
Structure and Components
- Plasma Membrane: Semi-permeable membrane that surrounds the cell, regulating what enters and leaves.
- Cytoplasm: Gel-like substance inside the cell membrane, where metabolic processes occur.
- Cytoskeleton: Network of protein filaments that provides structural support, shape, and movement.
Organelles
- Nucleus: Contains genetic material (DNA), regulates cell growth and reproduction.
- Mitochondria: Generates energy for the cell through cellular respiration.
- Endoplasmic Reticulum (ER): Involved in protein synthesis, transport, and storage.
- Ribosomes: Site of protein synthesis.
- Golgi Apparatus: Modifies and packages proteins and lipids for transport.
- Lysosomes: Contains digestive enzymes, breaks down and recycles cellular waste.
- Peroxisomes: Involved in fatty acid breakdown and amino acid metabolism.
- Centrioles: Involved in formation of cilia, flagella, and spindle fibers.
Functions
- Metabolism: Energy production, protein synthesis, and nutrient breakdown.
- Growth and Reproduction: Cell division, DNA replication, and protein synthesis.
- Response to Stimuli: Cellular signaling, response to hormones, and environmental stimuli.
- Waste Management: Breakdown and recycling of cellular waste.
Unique Features
- Centrioles: Present in animal cells, but not in plant cells.
- Lysosomes: More prominent in animal cells than in plant cells.
- Cilia and Flagella: Present in some animal cells, involved in movement and sensation.
