Study Notes
Cell Theory
- A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.
- The cell theory states that all living organisms are composed of cells.
Organelles and Their Functions
- Cytoplasm: The jelly-like substance filling the cell, surrounding organelles and containing nutrients.
- Cell Membrane: The boundary controlling what enters and exits the cell.
- Nucleus: The "brain" of the cell, containing DNA.
- Nucleolus: Inside the nucleus, responsible for ribosome production.
- Mitochondria: The "powerhouse" of the cell, converting sugar into usable energy.
- Rough Endoplasmic Reticulum: Ribosome-studded, involved in protein synthesis and folding.
- Smooth Endoplasmic Reticulum: Lacks ribosomes, involved in lipid synthesis and toxin breakdown.
- Golgi Apparatus: Packages and ships proteins.
- Lysosomes: Recycling centers, breaking down waste.
- Vacuoles: Store nutrients, waste, and water; in plants, the central vacuole maintains structure.
- Chloroplasts: Found in plant cells, convert sunlight to energy via photosynthesis.
- Cell Wall: Provides support and protection for plant cells.
Importance of Organelles
- Organelles are critical for cell function.
- Each organelle has a specific job, contributing to the cell's efficiency and survival.
