    • Eukaryotic Cells



      Eukaryote cells have membranous organelles,
      including a nucleus.


      The first eukaryotic cells are thought to have been protists. They gave rise to fungi, plants, and animals. The
      diagram below shows evolutionary relationships among the 4 kingdoms.



      The oldest fossils of eukaryotic cells are 1.5 billion years old although the
      earliest eukaryotic cells may have arisen 2.1 billion years ago. The oldest
      fossils of prokaryotes are 3.6 billion years old.

  • Animal Kingdom on 2007-09-06

    • Characteristics
      of animals
      A. Many-celled organisms
      B. Cells have a membrane around the
      nucleus
      C. Get nutrients and energy by eating other organisms
      D. Reproduce
      with eggs. Some eggs develop inside the mother's body, and some develop outside
      the mother's body.
      E. Examples are bears, fish, frogs, butterflies, and
      starfish

  • Plant Kingdom on 2007-09-06

    • Characteristics
      of plants
      A. Many-celled organisms
      B. Cells have a membrane around the
      nucleus, contain chlorophyll, and have cell walls
      C. Get energy from the sun
      and take in nutrients from their surroundings
      D. Most reproduce from seeds; some
      reproduce from other special parts
      E. Examples are ferns, trees, grasses, and
      bushes

  • Fungi Kingdom on 2007-09-06

      Cells have a membrane around the nucleus
      C. Get nutrients and energy by
      absorbing/ digesting the surface they live on




      D. Most
      reproduce by spores
      E. Examples are yeast, mushrooms, bread molds, and
      lichens

  • Protist Kingdom on 2007-09-06


    • Characteristics
      of protists
      A. Most are one-celled, but some have many cells
      B. Cells have
      a membrane around the nucleus
      C. Some get nutrients and energy by eating
      other organisms




      D. Some get
      energy from the sun, and nutrients from the water around them
      E. Most
      reproduce by splitting in two
      F. Examples are paramecium, amoeba, and
      kelp

    • Characteristics of monerans
      A. One-celled organisms
      B. Cells
      have no membrane around the nucleus





      C. Reproduce by splitting
      in two
      D. Absorb nutrients from outside their bodies
      E. Some monerans cause diseases,
      but others are helpful to people
      F. Examples: bacteria
