Study Notes
Fungi
- Fungi play a crucial role in the ecosystem by breaking down dead organic matter, releasing nutrients back into the soil, and allowing plants to utilize them.
- Some fungi can cause diseases, while others, like penicillin, are beneficial to humans.
- Yeast, a type of fungi, is used to make bread rise and to ferment beer and wine.
- Characteristics of fungi:
- Unicellular and multicellular organisms
- Cannot manufacture their own food
- Reproduce with spores
- Cannot move
Bacteria
- Bacteria are microscopic organisms, requiring a microscope to be seen.
- Characteristics of bacteria:
- Some may move
- Can manufacture their own food (some species)
- Divide to become more
- Bacteria are alive, as they exhibit certain life processes.
Protista
- Protista are microscopic organisms, requiring a microscope to be seen.
- Characteristics of protista:
- Unicellular, but not always
- Eukaryotic cells with a membrane around the core
- Need a fluid medium to live
- Protista, like Plankton, are unable to eat and must make their own food through photosynthesis.
Vertebrates
-
Animals are classified into vertebrates (with a spine) and invertebrates (without a spine).
-
Vertebrate animals are subdivided into five classes: fish, amphibians, reptiles, birds, and mammals.
-
Characteristics of vertebrates:
- Have a vertebral column (spine) with a cavity containing nerve cells
- Skeletons are made of bone
- Have an endoskeleton
-
Examples of vertebrates: dolphin, dog, goose, and others.
