  • 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 a system in biological terms?
    A system is made up of organs
  • What are organelles in a cell?
    Structures that perform different jobs
  • What is the function of the plasma membrane?
    Protects the cell and regulates entry
  • How does the plasma membrane function like city walls?
    It allows substances in and out
  • What is cytoplasm?
    Liquid jelly filling the cell
  • What happens in the cytoplasm?
    Many chemical reactions occur
  • What is the nucleus of a cell compared to?
    The town hall of a city
  • What surrounds the nucleus?
    A double membrane with nuclear pores
  • What is the nucleolus compared to?
    A library within the nucleus
  • What is produced in the nucleolus?
    Ribosomes are made there
  • What do ribosomes do?
    Make proteins
  • Where are the instructions for making proteins found?
    In DNA
  • What are ribosomes in eukaryotic cells called?
    80S ribosomes
  • What is the rough endoplasmic reticulum covered in?
    Ribosomes
  • What does the smooth endoplasmic reticulum produce?
    Lipids
  • What is the function of the rough endoplasmic reticulum?
    To make lots of proteins
  • What are vesicles compared to?
    Little taxis carrying substances
  • What does the Golgi apparatus do?
    Modifies and packages proteins
  • How is the Golgi apparatus like a post office?
    It packages and sends substances
  • What do lysosomes contain?
    Digestive enzymes
  • What are lysosomes known as?
    Rubbish collectors
  • What do lysosomes do with old organelles?
    They destroy them
  • What are centrioles involved in?
    Cell division
  • What do centrioles look like?
    Two hollow tubes at right angles
  • What is the function of mitochondria?
    Where respiration happens
  • What chemical energy is produced by mitochondria?
    ATP (adenosine triphosphate)
  • What is unique about the inner membrane of mitochondria?
    It has many folds for surface area
  • What does the matrix in mitochondria contain?
    Ribosomes and DNA
  • What type of ribosomes are found in mitochondria?
    70S ribosomes
  • What does the presence of 70S ribosomes in mitochondria suggest?
    They may have evolved from prokaryotic cells
  • What are the main organelles in an animal cell and their functions?
