Study Notes
Classifying Protists
- Protists are challenging to classify due to complex relationships that are hard to define.
- Protists can obtain food by consuming other organisms, through photosynthesis, or by decomposing organic matter.
- Plant-like protists possess chlorophyll, enabling photosynthesis.
- Amobas are known for their movement using pseudopodia.
- Animal-like protists use cilia for movement.
- Euglena, a unique protist, has both an eyespot and flagella for light detection and movement.
Historical Impact of Protists
- The Great Potato Famine occurred in Ireland; a fungus caused widespread rot in potatoes, leading to a devastating food shortage.
- Malaria is caused by the protist Plasmodium, which is transmitted through mosquito bites.
Types and Functions of Protists
- Protozoa are classified as animal-like protists.
- Dinoflagellates are known for causing red tides.
- Lichens represent a mutualistic relationship between fungi and algae or photosynthetic bacteria.
- Slime molds and water molds are examples of fungus-like protists.
- Red, green, and brown algae are collectively known as seaweed.
Fungi Characteristics
- Ciliates are a type of protozoa characterized by their cilia.
- Fungi are responsible for diseases like ringworm and athlete's foot.
- The primary distinction between animals and animal-like protists is that animal-like protists are single-celled.
- Animal-like protists are heterotrophic, meaning they cannot produce their own food and rely on other organisms.
- Fungi have cell walls composed of chitin, which distinguishes them from plant cells.
Kingdom Protista
- The Protista kingdom is often referred to as the "misfit kingdom" due to its vast diversity.
- Plant-like protists can reproduce both sexually and asexually.
Unique Fungal Characteristics
- Truffles are found in the Fungi kingdom and are uniquely located by animals such as pigs and dogs using their sense of smell.
- Common types of fungi include mushrooms, truffles, and yeast.
Review Structure
- Study materials may include various formats such as 10 true/false questions, 10 fill-in-the-blank questions, and 5 multiple-choice questions.
