Cells

• What are cells considered to be in living organisms?

  Building blocks of living things
• How do cells relate to tissues and organs?

  Cells of the same type form tissues
• What is the role of systems in organisms?

  Systems are made up of organs
• What is the plasma membrane's function?

  Protects the cell and regulates entry
• How does the cytoplasm function within a cell?

  It contains dissolved substances and reactions
• What is the role of the nucleolus?

  It produces ribosomes from DNA
• What do ribosomes produce?

  Proteins
• How are ribosomes in eukaryotic cells different from prokaryotic cells?

  Eukaryotic ribosomes are called 80s
• What is the function of rough endoplasmic reticulum?

  It synthesizes proteins
• What is the role of smooth endoplasmic reticulum?

  It synthesizes lipids
• What does the Golgi apparatus do?

  Modifies and packages proteins
• What are vesicles compared to in the cell?

  Little taxis
• What are lysosomes known as?

  Rubbish collectors
• What is the function of lysosomes?

  They digest old organelles and pathogens
• What is the role of centrioles in the cell?

  Involved in cell division
• What do mitochondria produce?

  ATP through respiration
• What is unique about the ribosomes in mitochondria?

  They are 70s ribosomes
• How do mitochondria relate to evolutionary theory?

  They suggest a symbiotic relationship with prokaryotes
• Plasma membrane (Animal cell)


  • Protects the cell from its surroundings
  • Allows substances in and out
• Plasma membrane Structure(animal cell)


  • Composed of a phospholipid bilayer, with proteins embedded in the layer
• Plasma membrane Function (Animal Cell )


  • The membrane is selectively permeable and regulates the transport of materials into and out of the cells contents from the outside environment
• Cytoplasm(Animal cell)


  • Liquid that fills the cell
  • Contains many dissolved substances
  • Lots of chemical reactions happen in it
• Cytoplasm Structure(Animal cell)


  • It is a thick, gelatinous , semi-transparent fluid
• Cytoplasm Function (Animal cell)

  • Maintains cell shape and stores chemicals needed by the cell for metabolic reactions
• Nucleus (Animal cell)

  • Surrounded by a double membrane (envelope)
  • With nuclear pores
• Nucleus Structure (Animal cell)

  • Largest organelle and is surrounded by a nuclear envelope. The envelope has nuclear pores which allow the movement of molecules through it. The nucleus contains chromatin.
• Nucleus Functions (Animal cells)

  • The nucleus controls / regulates cellular activity and houses genetic material called chromatin, DNA and Proteins, from which comes the instruction for making proteins
• Nucleolus (Animal cell)

  • Region of dense DNA
  • Produces ribosomes
