    Study Notes

    Cell Basics

    • There are two main types of cells: Prokaryotic cells (lacking a true nucleus) and Eukaryotic cells (having a true nucleus).

    Cell Membrane

    • The plasma membrane is a thin, flexible layer that surrounds a cell and regulates the movement of substances in and out of the cell.

    Ribosomes

    • Ribosomes are small organelles found throughout the cytoplasm, responsible for protein synthesis, where they translate messenger RNA (mRNA) into polypeptide chains.

    Functions of Living Things

    • Living organisms composed of cells can perform basic functions, including:
      • Metabolism: obtaining and utilizing energy
      • Homeostasis: maintaining a stable internal environment
      • Growth and Development: increasing in size and complexity
      • Reproduction: producing offspring
      • Response to Stimuli: reacting to changes in the environment
      • Evolution: adapting to the environment through genetic changes

    Organelles

    • Organelles are specialized structures within a cell that perform specific functions, such as energy production, protein synthesis, and waste management, allowing the cell to maintain homeostasis and carry out its daily functions.
