The Three Domains of Life
How are eukaryotes more
closely related to?
1
Domain: Bacteria
•
Cell type: prokaryotic
•
Unicellular (but some form colonies)
•
How do they obtain their organic molecules?
Some are autotrophs (cyanobacteria)
and others are heterotrophs by absorption
decay material, living on organisms, free living
Few bacteria cause disease
Bacteria shapes: fill out table 1 using poster
2
Procedure 1: Bacteria sensitivity to Antibiotics
Consumer report
Procedure 2: Nitrogen fixation
Legume plants house nitrogen fixing
bacteria in bulbs of root tissue
called nodules
3
Procedure 3: Photosynthetic Bacteria
Decomposer Bacteria
4
Bacteria are used in the food industry
and in medicine
Kingdoms of Domain Eukarya
•
Characteristic of all Eukaryotes
Cell type: eukaryotic
•
An important characteristic
for dividing eukaryotes into
Kingdoms is by:
•
How do they obtain
their organic molecules?
Kingdom Plantae: autotrophs
Kingdom Animalia:
Heterotrophs by ingestion
Kingdom Fungi: Heterotrophs by absroption
•
How about protists?
5
Excercise11: Kingdom Protista
Mostly unicellular but there are some multicellular forms
How do they obtain their organic molecules?
Some are heterotrophs by absorption
some are heterotrophs by ingestion
and others are autotrophs
Procedure 1: Protist locomotion
6
Procedure 2: Protist nutrition
Importance of some protista
7
Important some Protista
Trypanosoma causes
Chagas disease
Plasmodium causes
Malaria disease
Ex. 11:Kingdom Fungi
- Cells with cell wall of chitin (carbohydrate)
- Heterotrophs by absorption
important ecologically as decomposers
- Body is composed of hyphae
(threads of cytoplasm and nuclei)
mass of hyphae  mycelium
- Reproduction:
asexual and/or Sexual reproduction
both by spores
Sporangium (pl. sporangia) structure that
produces spores

P 3. Division Zygomycota: Rhizopus(bread mold)
Mycelium
Sporangium
Gametangia
Zygospore
P 4. Divison Ascomycota: sac fungi
(yeast)
9
P 5. Division Basidiomycota: club fungi (mushrooms)
Mushroom parts:
Cap
Gills
Basidia
Importance of Fungi:
decomposers, food, medicine and food industry
