    The smallest and most basic fundamental unit of life is the cell.
  • What does the term 'organism' refer to in biology?
    The term 'organism' refers to any individual form of life, including both unicellular and multicellular forms.
  • What is the difference between unicellular and multicellular organisms?
    Unicellular organisms consist of a single cell, while multicellular organisms are composed of multiple cells.
  • How are unicellular organisms typically observed?
    Unicellular organisms are usually so small that they can only be seen with microscopes.
  • What does the root 'uni' in 'unicellular' mean?
    The root 'uni' in 'unicellular' means one.
  • What does the root 'multi' in 'multicellular' mean?
    The root 'multi' in 'multicellular' means multiple or many.
  • Why are humans considered multicellular organisms?
    Humans are considered multicellular organisms because they consist of trillions of cells.
  • What is an example of a multicellular organism?
    An example of a multicellular organism is a human being.
  • What is an example of a unicellular organism?
    An example of a unicellular organism is a single-cell bacterium.
  • What is the definition of biology?
    Biology is the scientific study of life.
  • What is the fundamental unit of life?
    The cell is the fundamental unit of life.
  • What is a unicellular organism?
    A unicellular organism is a form of life that consists of just a single cell.
  • What is a multicellular organism?
    A multicellular organism is a form of life that consists of multiple cells.
  • What does the term 'organism' refer to in biology?
    The term 'organism' refers to any individual form of life.
  • Give an example of a multicellular organism.
    Humans are an example of multicellular organisms.
  • What does the prefix 'uni-' mean in the term 'unicellular'?
    The prefix 'uni-' means one.
  • Can the term 'organism' be applied to both bacteria and humans? Why or why not?

  • Why is the cell considered the most basic unit of life?
    Because all living things are made up of cells, and cells carry out the essential functions of life.
  • Are all forms of life visible to the naked eye? Explain.
    No, most life forms, especially unicellular organisms, are too small to be seen without a microscope.
