Study Notes
Animal and Plant Cell Structure
- Cell Membrane: Provides structure and support; regulates what enters and exits the cell.
- Cytoplasm: Gel-like substance filling the cell, supporting organelles and facilitating chemical reactions.
- Endoplasmic Reticulum: Essential for the transport of materials; can be rough (with ribosomes) or smooth (without ribosomes).
- Golgi Apparatus: Modifies, sorts, and packages proteins and lipids for transport.
- Mitochondrion: Known as the "Power House" of the cell; responsible for cellular respiration and energy production.
- Nucleus: Acts as the control center; stores DNA and regulates cellular activities, including reproduction.
- Vacuole: Functions as a storage unit for food, water, waste, and other substances within the cell.
- Cell Wall: Rigid outer layer found in plant cells; provides additional support and protection.
Differences Between Cell Types
- Plant Cell: Contains a cell wall, chloroplasts for photosynthesis, and a large central vacuole.
- Animal Cell: Lacks a cell wall and chloroplasts, features a smaller vacuole.
Unique Organelles and Structures
- Chloroplast: Site of photosynthesis in plant cells, converting light energy to chemical energy.
- Lysosomes: Contain enzymes for digesting cellular waste and foreign materials.
- Nucleolus: Dense structure within the nucleus responsible for ribosomal RNA synthesis.
- Nuclear Membrane: Double-layered membrane enclosing the nucleus, continuous with the endoplasmic reticulum.
Additional Cell Components
- Ribosomes: Small particles composed of RNA and proteins; essential for protein synthesis by translating messenger RNA.
- Organelles: Specialized structures within cells, each performing specific functions vital for cell survival and efficiency.
Summary of Cell Fundamentals
- Cell: The basic unit of life; all living organisms are made of cells.
- Mitochondria and Chloroplasts are crucial for energy production in their respective cell types.
- Vacuoles serve as storage compartments, playing vital roles in maintaining cell homeostasis.
