  • Living things have movement, nutrition, respond, waste, reproduce, grow, exchange gases, water
  • Prokaryotes are unicellular, have no nucleus and have no membrane bound organelles
  • Eukaryotes are multicellular, have a nucleus and have membrane bound organelles
  • Fungi, animals, plants, and protists are eukaryotic
  • Bacteria are an example of prokaryotes
  • In eukaryotes, DNA is found in the nucleus
  • DNA is stored in the cytoplasm in prokaryotes
  • specialised cells -> tissue -> organ -> system -> organism
  • The cytoplasm gives a cell its shape and holds the organelles inside
  • The nucleus is the control centre of the cell
  • nucleolus is found in the cell's nucleus and it produces and assembles ribosomes
  • The plasma membrane is made up of two layers of lipids
  • The cell membrane controls the substances that enter and exit the cell
  • Mitochondria generates energy to power the cell's activities
  • Smooth endoplasmic reticulum detoxifies the cell and lipid production
  • The rough endoplasmic reticulum's function is protein production
  • Ribosomes are made of RNA and proteins and is the site of protein synthesis
  • Nucleus contains DNA and directs all cellular activity
  • Golgi apparatus processes and packages proteins (shipping departement)
  • Lysosome breaks down waste material, dead cells, and pathogens through using digestive enzymes
  • Cell wall is a rigid structure that surrounds the cell and provides support and protection.
  • Chloroplasts produces energy through photosynthesis
  • Photosynthesis requires chlorophyll, sunlight, carbon dioxide and water
  • In animal cells, vacuoles help in storage and disposal of substances
  • In plant cells, vacuoles help maintain water balance
