Q

Autorophs

A

Photoautrophs - convert solar energy into CO2 and water into sugar and produce O2 (Bacteria)

18
Q

Reproduction

A

Archaea and bacteria reproduce asexually

19
Q

Characteristics of Protists

A

Eukaryotes
Majority unicellular
Diverse

20
Q

Classifications of Protists

A

Protza(Animal Like) - heterotrophs that ingest or absorb food
Slime Moulds and Water Moulds(Fungi Like) - absorptive heterotrophic protists
Algae(Plant Like) - Autotrophic protists that carry out photosynthesis

21
Q

Protza

A

Cercozoa
Cilliophora
Zoomastigina
Sporozoa

22
Q

Cercozoa

A

Most familiar = amoebas
Have cell membrane, but no cell wall
can create temporary extensions of cytoplasm (pseudopods)

23
Q

Cilliophora

A

Most familiar = paramecium
Have many short hairs(cilia)
Cilia used for feeding and movement

24
Q

Zoomastigina

A

They have more than one flagellum(long hair like structure) that propels them

25
Q

Sporozoa

A

Parasitic nonmotile protozoans
Most have life cycles w alternate between sexual and asexual reproduction
Ex: Produce sexually in mosquitos
Produce asexual in human liver

26
Q

Slime mould and water moulds

A

Myxomycota
Acrasiomycota
Oomycota

27
Q

Myxomycota

A

Visible, slug like organism
creep over damp decaying particles
feed my engulfing small particles into their cytoplasm

28
Q

Acrasiomycota

A

Exists as single cells, but when food is scarce they release a chemical and join together

29
Q

Oomycota

A

Most live on dead organic matter and resemble fungi
They extend fungus like threads into host and release digestive enzymes that absorb nutrients

30
Q

Algae

A

Chrystophyta
Pyrrophyta
Euglenophyta

31
Q

Multicellular Algae

A

Rhodophyta(Red)
Phaeophyta(Brown)
Chlorophyta(Green)

32
Q

Chrystophyta

A

Diverse group of phytoplankton
autotrophic
rigid cell wall with an outer layer of silica

33
Q

Pyrrophyta

A

Phytoplankton with 2 flagella
reproduce quickly
red tide
Tend to have a mutualistic relationship with coral reefs

34
Q

Euglenophyta

A

have chloroplast and can preform photosynthesis, but also have flagella and can absorb nutrients
Autotrophic in light, heterotrophic in darkness

35
Q

Red Algae

A

1st multicellular organism on earth

36
Q

Brown Algae

A

Largest protist

37
Q

Green Algae

A

Structurally diverse
Most plant like
