Cell Structure & Pro/Eukaryotes

• Mitochondria are responsible for aerobic respiration - this process releases energy that can be used by the cell
• Plant cells contain

  cell wall

  cell membrane

  cytoplasm

  ribosomes

  mitochondria

  vacuole

  chloroplasts

  nucleus
• Animal cells contain:

  Cell membrane

  cytoplasm

  ribosomes

  nucleus

  mitochondria
• The differences between Eukaryotic and prokaryotic cells are:

  • E-cells have a nucleus
  • E-complex, they are animal and plant cells
  • E-arrived around 2 billion years ago
  • P-NEVER have mitochondria/chloroplasts
  • P-tend to have plasmids
  • P-circular/twisted strand of DNA
  • P-sometimes have flagella
  • P-tend to be smaller than eukaryotes
• A eukaryote is any living thing whose cells have a true nucleus enclosed within membranes.
• Bacteria is an example of Prokaryote
• If askd to estimate the area of a subcellular structure, what to do?

  Treat it like a regular shape, eg: if it were mostly rectangular, work out the area of that rectangle.
• plant cell walls are made out of and why re they good?

  made out of cellulose, holds up the cells and gives support
• prokaryotic cells dont have what

  nucleus

  mitochondria

  chloroplasts
• Animal& Plant cells havein common

  cell membrane that is semi permeable

  mitochondria

  ribosomes

  nucleus

  cytoplasm
• Plant cells have what that animals cells dont

  Cell wall

  chloroplasts

  permanent vacuole
• mitochondria is where what takes place

  respiration takes place releasing energy for the cell to function
• ribosomes are where

  proteins are synthesized
• plant cells have vacuoles which contains

  cell sap, water ect
