Lesson 7: Organelles in cells

Hi,

You may want to view these Powerpoint slides before attempting the worksheet on this topic.
the coverage includes the following:
  • onion and cheek cells
  • cell organelles
  • cell membrane-covers cell allow materials in or out of cell
  • cell wall-covers plant cell, for support and strength
  • cytoplasm-houses all cell organelles
  • golgi body-processes materials and packages them for transport
  • mitochondria-site where ATP, energy, is released during cellular respiration
  • nucleus-contain chromosomes/DNA, controls all cell activities, involved in cell division
  • endoplasmic reticulum-packages the proteins from ribosomes
  • chloroplast-make glucose/food using sunlight energy
  • vacuole-stores water, wastes and nutrients
  • ribosome-site where protein is made
  • centrioles- involved in cell division



Cheers
