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.
