    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.
