The cell theory states...
  • 1. cells are the smallest unit of life
  • 2. all living things are made up of cells
  • 3. all cells come from pre-existing cells
Give four scientists who contributed to the development of the cell theory and their contribution.
  • Hooke: cork
  • Brown: nucleus
  • Leeuwenhoek: bacteria
  • Flemming:mitosis of cells
Two technological advances essential for the development of the cell theory are:
  • Light microscope: viewed cells, cell membrane & wall, cytoplasm, nuclues, chloroplasts and vacuoles
  • Electron microscope: mitochondria, Golgi bodies, lysosomes, ER, ribosomes
Answer
Mitochondria which is the site of cellular respiration (oxygen + water > glucose + carbon dioxide + water)
Answer
Chloroplast which is the site of photosynthesis (water + carbon dioxide in the presence of light > glucose + oxygen)
Answer
Golgi body where final synthesis and packing of proteins take place
