What is a Protist

Prodominantly unicellular junk drawer of Eukarya kingdoms: If an organism does not neatly fit into either Plantae, Fungi, or Animalia, it is thrown into Protista.

are Protists autotrophs or heterotrophs

Protists may be either

Examples of helpful and harmful protists

Helpful: composting, digestion in certain insects (many symbiotic relationships)

Harmful: malaria, potato famine

Are Fungi heterotrophs or autotrophs

heterotrophs

Are fungi unicellular or multicellular

They are predominantly multicellular; however, they may be unicellular

Are fungi plants

no, fungi are actually genetically closer related to animals to plants

Do fungi reproduce sexually or asexually

can be either, often with the use of spores

What is the cell wall of Fungi made of

Carbohydrate called Chitin

What is a Hyperparasite

a parasite that infects a parasite

Example of how fungi can be helpful and harmful

Helpful : composting, food sources, medicine (penicillin)

Harmful : ringworm, athlete’s foot

What are the two categories of plants

• Vascular: get water and transport using xylem; transport nutrients with phloem

• Nonvascular: limited in size, found in areas with moisture

How do Nonvascular plants absorb water?

Nonvascular plants, also known as bryophytes, informally absorb water like a sponge via osmosis

What are the three key groups of Vascular plants

• Seedless vascular (seedless)

• Gymnosperms (seeds exposed)

• Angiosperms (flowering plants)
