Study Notes

Protista

  • Kelp is a multicellular, marine organism that is photosynthetic and has motile sperm cells.
  • Paramecium is a fast-swimming, unicellular organism with cilia, found in pond water, and feeds on bacteria via endocytosis.
  • Slime Mold can be unicellular or multicellular; it forms a bright orange mass before reproducing and feeds on dead leaves by absorbing nutrients.
  • Algae is a thread-like, multicellular organism that resides in water, reproducing through sperm and causing a vibrant green coloration when populations surge.

Eubacteria

  • E. Coli is a single-celled, prokaryotic bacterium living in mammals' large intestines and reproduces rapidly through binary fission.
  • Pseudomonas is a single-celled organism lacking a nucleus, known for causing foul odors as it decomposes dead animal tissues.

Plantae

  • Apple Trees are multicellular autotrophs that produce flowers containing eggs and pollen, and secrete seeds within fruits.
  • The Venus Flytrap is a multicellular, photosynthetic plant that generates glucose from sunlight while obtaining nutrients from insects through specialized leaves.

Animalia

  • Cows are multicellular heterotrophs that consume grass and rely on sexual reproduction.
  • Hawks are fast-moving, predatory birds with excellent vision, primarily feeding on ducks, and possess complex organ systems.

Fungi

  • Mushrooms are large, multicellular organisms hidden beneath soil; they produce spores in fruiting bodies and decompose dead plant material as they grow.
  • Shelf Fungus lives inside trees, digesting wood and eventually killing the host tree; it exists as a whitish mycelium that begins from spores landing on tree wounds.
