Study Notes

Cell: The Structural and Functional Unit of Life

  • Living things are made up of cells, which are the basic units of life.
  • Cells contain special parts called cell organelles, which have specific structures and functions.

Levels of Organisation

  • A group of similar cells form a tissue.
  • A group of tissues form an organ.
  • Organs together form an organ system.
  • Understanding cells, tissues, organs, and organ systems helps us understand the levels of organisation in multicellular organisms.

Parts of Cell and their Functions

  • Cell organelles are present in the cytoplasm of a cell.
  • Cell organelles have definite shape, size, and function.
  • Examples of cell organelles and their functions:
    • Nucleus: unknown
    • Cytoplasm: unknown
    • Other organelles: unknown

Learning Objectives

  • Identify cell organelles of plant and animal cells.
  • Explain the functions of cell organelles.
  • Draw labelled diagrams of plant and animal cells.

Cell Organelles and their Functions

  • See Table 1.1 for cell organelles and their functions.

This quiz covers the basics of cell structure and function, including cell organelles, tissues, organs, and organ systems in multicellular organisms.
