Protists and Fungi
2
Kingdom Protista

• Plant-like, animal-like, or fungus-like
• Heterotrophs or autotrophs
• Most unicellular, some multicellular

3
Plant-like protists

• Algae
• Photosynthetic
• Basis of the marine food chain
• Make most of the oxygen in the atmosphere

4
Plant-like protists
5
Plant-like protists

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

Sea lettuce
6
Plant-like protists

• Move using flagella
• Have chlorophyll for photosynthesis

euglena
7
Animal-like protists

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

8
Animal-like protists

• Sporozoans reproduce using spores

Plasmodium carried by mosquitoes causes
malaria
9
Fungus-like protists

• Slime molds
• Water molds and downy mildew

Kingdom Fungi
11
What are the characteristics of fungi?
Some unicellular, most multicellular
Eukaryotes
Cell walls made of chitin
Body structure is made up of hyphae
12
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
13
Parasitic fungi
Athletes foot
Bracket fungi
14
Saprophytic fungi
Mycena
Shitake mushroom
15
Mutualistic fungi
British soldier lichen
vesicular-arbuscular mycorrhiza
Green shield lichen
16
Fungi Reproductioncan be asexual
fragmentation
budding
spores
17
Fungi Reproductioncan be sexual
Specialized hyphae from two individual fungi meet
and form a new individual.
