    Study Notes

    Cell Membrane

    • Composed of a double layer of phospholipids; hydrophilic heads and hydrophobic tails
    • Regulates entry and exit of materials through membrane pores

    Cytoplasm

    • A gel-like fluid that includes cytosol and various organelles
    • Provides a medium for biochemical reactions and helps in transportation within the cell

    Vacuole

    • Membrane-bound sac primarily for storage of nutrients, water, and waste
    • Plant cells typically possess a single large vacuole, while animal cells have multiple smaller ones
    • Plays a role in cell growth by increasing cell size

    Mitochondrion

    • Also known as the powerhouse of the cell
    • Enclosed by double membranes, facilitating energy (ATP) production through cellular respiration

    Golgi Body

    • Receives, processes, packages, and distributes proteins and lipids from the endoplasmic reticulum
    • Functions in the modification and transport of molecules to various parts of the cell

    Lysosome

    • Contains digestive enzymes for breaking down food particles, waste, and pathogens
    • Critical for intracellular digestion and recycling of cellular components

    Nucleus

    • Houses the cell's genetic material (DNA) and regulates cell activities
    • Considered the control center of the cell, influencing growth, metabolism, and reproduction

    Cell Wall

    • A rigid outer structure exclusive to plant cells that provides protection and shape
    • Composed of polysaccharides like cellulose, contributing to structural integrity

    Ribosomes

    • Small organelles that facilitate protein synthesis by assembling amino acids
    • Composed of RNA and proteins, existing as two subunits: large and small

    Cytoskeleton

    • An organized network of microtubules, actin filaments, and intermediate fibers
    • Maintains cell shape and supports internal movement of organelles and muscle fiber contraction

    Chloroplast

    • Found only in plant cells, containing chlorophyll for photosynthesis
    • Enclosed by a double outer membrane, critical for converting solar energy into food

    Membrane Protein

    • Embedded in the cell membrane, participating in cell communication and responses
    • Includes marker proteins for immune identification, channel proteins for substance transport, and receptor proteins for signal reception

    Endoplasmic Reticulum

    • A labyrinthine structure that transports proteins and materials within the cell
    • Divided into rough (with ribosomes) and smooth (without ribosomes) types, each serving distinct functions in metabolism and protein synthesis
