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: • 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:
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: Athlete’s foot Bracket fungi
Saprophytic fungi: Mycena Shitake mushroom
Mutualistic fungi: British soldier lichen vesicular-arbuscular mycorrhiza Green shield lichen
Fungi Reproductioncan be asexual: fragmentation budding spores
Fungi Reproductioncan be sexual: Specialized hyphae from two individual fungi meet and form a new individual.
