Cell/Microscope Review



Levels of organization

Cells

Tissues

Organs

Organ Systems

Organism

Levels of Organization


Characteristics of living things

are made up of cells (organization)

respond to the environment

have the ability to reproduce

move

grow and develop

Characteristics of Living Things


Needs for life

  • Organisms need energy, materials, and living space

  • All energy comes from the sun.

    • Some organisms use this energy directly (photosynthesis)

    • Others harness this energy by eating food

  • Materials needed:

    • Carbon dioxide, oxygen, nitrogen, water

  • Living Space

Needs for life…


Cell t heory

Every living thing is made up of one or more cells.

Cells carry out the functions needed to support life

Cells come only from other living cells

Cell Theory…


Scientists who have contributed to cell theory

Anton von Leeuwenhoek: Invented the microscope and observed tiny living things in water

Robert Hooke: Coined the term “cell” after Review of Cell Theory observing that cork consisted of tiny chambers

Francesco Redi: Proved that living things cannot be produced from non-living matter

Louis Pasteur: Discovered that cells come only from other living cells

Scientists who have contributed to Cell Theory



Two types of cells
