Cell Theory

Scientists developed the cell theory after discovering that all living things are made up of cells (microscope)

Cell Theory Definition:

  • an explanation that summarizes the basic characteristics of living things

Cell Theory:

  • 1. All living things are composed of one or more cells

  • 2. The cell is the basic unit of life

  • 3. All cells come from pre-existing cells

Cell Theory

  • One of the first concepts developed in Biology

Theodor Schwann

D

  • 1810-1882

  • German physiologist

  • Found that animal tissues were composed of cells

  • All living things are made up of cells

C

Rudolf Virchow

  • 1821-1902

  • His work focused on disease

  • He found that disease arose in individual cells and not in the organs/tissues

  • proposed that all cells originate from pre-existing cells

B

Plant Cells

Matthias Jacob Schleiden

  • 1804-1881
  • He studied plant structure under the microscope
  • Recognized the importance of the cell nucleus
  • Credited as the first scientist to find that plant tissues were composed of cells

Nerve Cells

A

Allow animals (humans) to respond to changes in their environment

Smooth muscle cells

Assists with moving food through the digestive tract

Smooth muscle cells

Robert Hooke

  • 1635-1703

  • He was the first to identify cells and coined the term

  • recognized as one of the most important scientists of his age

Invented the 3 lens microscope

  • famous for studying the thin slices of cork

  • cell walls in cork tissue

  • fly’s eye

Anton van Leeuwenhoek

Anton van Leeuwenhoek

  • 1632-1723

  • Known for the development and improvement of the microscope

  • Observed cells in greater detail

  • First to observe single-celled organisms

Cell Theory

  • All living things are made of one or more cells
  • The cell is the basic unit or life in all living organisms
  • Cells come only from other living cells

Modern Cell Theory

Living procesess

  • Movement
  • Respiration
  • Sensibility
  • Growth
  • Reproduction
  • Excretion
  • Nutrition

Living Things

Prokaryotic Cell vs.

Eukaryotic Cell

Prokaryote

Prokaryote

  • Bacteria and Archaea domains
  • Unicellular organism
  • Lack organelles
  • Lacks a membrane-bound nucleus
  • DNA found in the cytoplasm

Eukaryote

  • Animals, plants, fungi, protists
  • Unicellular or multicellular
  • Contains a nucleus
  • Organelles such as mitochondria, golgi bodies, lysosomes etc.

Organelles

  • Cellular structures that perform specific functions within the cell

  • Found within the cytoplasm
