Protists and FungiProtists and Fungi

Kingdom Protista

• Plant-like, animal-like, or fungus-like

• Heterotrophs or autotrophs

• Most unicellular, some multicellular

Plant-like protists:

• Algae

• Photosynthetic

• Basis of the marine food chain

• Make most of the oxygen in the atmosphere

Plant-like protists:

Plant-like protists:

• Alternation of generations- organism alternates between sexual (using eggs and sperm) and asexual (using spores) reproduction

Sea lettuce

Plant-like protists:

• Move using flagella

• Have chlorophyll for photosynthesis

euglena

Animal-like protists:

• Protozoans • Move about using cilia, flagella, or false feet• Many are decomposers

Animal-like protists:

• Sporozoans reproduce using spores

Plasmodium – carried by mosquitoes – causes malaria

Fungus-like protists:

• Slime molds:

• Water molds and downy mildew:

Kingdom Fungi

What are the characteristics of fungi?

Some unicellular, most multicellular

Eukaryotes

Cell walls made of chitin

Body structure is made up of hyphae

Fungi are heterotrophsthey can be:

Parasites - Absorb nutrients from the living cells of a host

Saprophytes - Decompose waste or dead organic material

Mutualists - Live in symbiosis with another organism

Parasitic fungi:

Bracket fungi Athlete’s foot

Saprophytic fungi:

MycenaShitake mushroom

Mutualistic fungi:

vesicular-arbuscular mycorrhiza

British soldier lichen

Green shield lichen

Fungi Reproduction

can be asexual:

fragmentation

budding

spores

Fungi Reproduction

can be sexual:

Specialized hyphae from two individual fungi meet and form a new individual.
