Study Notes
Parasites and Protists
- Hermaphrodites have both male and female reproductive organs.
- All protists possess a true nucleus, distinguishing them from prokaryotic organisms.
- Some protists have shells made of calcium carbonate, referred to as tests.
- Protists are classified based on resemblance to organisms in the kingdoms of fungi, animals, and plants, but not bacteria.
Euglenoids and Diatoms
- Euglenoids possess a stigma that helps them move toward light, aiding in photosynthesis.
- Diatoms feature photosynthetic pigments, an outer silicate layer, and are recognized for their abrasive properties.
Classification of Protists
- Examples of plant-like protists include Euglenoids, Diatoms, and Dinoflagellates; Amebozoans are not categorized as such.
- Animal-like protists are represented by apicomplexans, which are significant in various ecological roles.
- Water molds and slime molds share characteristics typical of fungi and animals.
Nutritional Strategies
- Saprophytes absorb nutrients from decaying matter and are classified as heterotrophs.
- Protozoa are always heterotrophic, feeding on organic matter.
Protozoan Movement and Types
- Mastigophorans are protozoa that utilize flagella for movement.
- Amebozoans, commonly found in human intestines, are known for their ameba-like movement.
- Apicomplexans are a non-motile protozoan group, including the pathogen that causes malaria.
Malaria Life Cycle
- The life cycle of Plasmodium involves stages: sporozoite → merozoite → trophozoite.
Fungi Characteristics
- Mycology is the study of fungi, characterized by cell walls made of chitin.
- Fungal hyphae may have cross walls, known as septa, separating them into compartments.
- Fungi are heterotrophs, but not obligate parasites; they can be saprophytes or facultative parasites.
Fungal Classification
- Fungi are classified based on the nature of their sexual cycle.
- Bread molds belong to the phylum Zygomycota.
- Fungi differ from plants primarily because they cannot photosynthesize, while plants can.
General Characteristics
- The largest protozoan group is the ciliates, known for their motility.
- All protists are eukaryotic, contrasting with prokaryotic microorganisms like bacteria.
