1. Cellular Organization and Components

Key Concepts & Definitions

  • Cell : The basic structural and functional unit of living tissues, and human cells are eukaryotic.

★ Must-know

  • The three major components are:
    • the plasma membrane
    • the cytoplasm
    • the nucleus

Further detail

  • The plasma membrane encloses the cell, the cytoplasm contains organelles, and the nucleus stores genetic material and controls cellular activity.

PM–C–N: plasma membrane, cytoplasm, nucleus

2. Organelle Membrane Classification

★ Must-know

  • The membrane classes are:

    • no membrane
    • single membrane
    • double membrane
  • Single-membrane organelles include:

    • the endoplasmic reticulum
    • the Golgi apparatus
    • lysosomes
    • peroxisomes
    • vesicles

Further detail

  • Non-membrane-bound organelles include:
    • ribosomes
    • the cytoskeleton
    • centrioles
