Questions and Answers

How are protists classified?

Protists are often classified by characteristics that resemble those of fungi, plants, and animals.

What are the general characteristics of Kingdom Protista?

Most are microscopic, single-celled or simple multicellular eukaryotic organisms, containing mitochondria and sometimes chloroplasts.

What are the 3 different types of protists?

Animal-like protists, plant-like protists, fungus-like protists.

Study Notes

Protists Classification

Protists are classified based on characteristics resembling fungi, plants, and animals.
Reproductive patterns of some protists mimic those of fungi.
Some protists conduct photosynthesis like plants, while others move and consume food similar to animals.

General Characteristics of Kingdom Protista

Most protists are microscopic and can be single-celled or simple multicellular eukaryotes.
Typically contain mitochondria; some possess chloroplasts, acting as autotrophs.
All protists have a nucleus and organelles, capable of both sexual and asexual reproduction.
Nutritional strategies include heterotrophs, autotrophs, or both.
Movement facilitated by flagella, pseudopods, or cilia.

Types of Protists

Three primary categories exist: animal-like, plant-like, and fungus-like protists.

Animal-like Protists

Utilize flagella, pseudopodia, or cilia for movement and can be autotrophic or heterotrophic.
Notable examples include amoeba, paramecium, and euglena.

Plant-like Protists

Have chloroplasts for photosynthesis; predominantly autotrophs.
Important in human diets, found in various foods and daily products like toothpaste and food coloring.
Examples include red algae, brown algae, and dinoflagellates.

Pros of Protists

Plant-like protists are beneficial in food and everyday products.
Serve a role in research regarding cellular disease protection.

Cons of Protists

Fungus-like protists (e.g., water molds) can infect crops like potatoes, leading to shortages.
Algal blooms caused by plant-like protists can contaminate water.
Certain animal-like protists are vectors for diseases such as malaria and giardiasis.

Organism Classification

Organisms are grouped based on characteristics such as fossils, symmetry, embryonic development, and ribosomal RNA.

Importance of Classification

Provides a universal scientific language and maintains organization.
Enables testing of theories and facilitates new biological discoveries.
Aids in protecting biodiversity.

Types of Classification Systems

Phylogenetic trees illustrate ancestral relationships among species.
Cladistics emphasizes shared and derived characteristics for grouping taxa.
The Linnaean system organizes classification hierarchically from domain down to species.

Phylums and Groups

Notable groups include slime molds and water molds.
Phylum Myxomycota (Plasmodial Slime molds).
Phylum Dictyostelida (Cellular Slime molds).
Phylum Oomycota and Phylum Chytridiomycota (both include water molds).

Role of Fungi in Ecosystems

Fungi recycle decaying matter alongside bacteria.
Contributes positively to the growth of most plants, including crops.

Mushrooms and Soil Contamination

Mycelium from mushrooms can absorb and convert oil-contaminated soil into a vibrant ecosystem after reproduction.

Mushrooms as Filtration Systems

Mycelium-infused burlap sacks used in runoff areas can effectively filter harmful bacteria from water.

Relation to Algal Blooms

Techniques explored for mitigating algal blooms include filtering out phosphorus pollutants.

Medical Potential of Mushrooms

Certain mushroom strains show resistance and potential to combat pox diseases and flu.

Comparison to Bacteria Unit

Effective antibiotics are derived from fungi, and both fungi and bacteria can be cultured in petri dishes for growth observation and measurement.

Contractile Vacuole

Essential for regulating water movement within protists, operating by opening and closing.
