Answer 7

Prokaryotic Cell

• lacks nucleus and membrane bound organelles
• cell wall lacks peptidoglycan

Question 8

Domain Eukarya

Answer 8

Eukaryotic Cell

-contains a membrane bound nucleus/organelles

Question 9

Domain Eukarya: 4 kingdoms

Answer 9

• Protista
• Fungi
• Plantae
• Animalia

Question 10

Domain Eukarya: Kingdom Protista

Answer 10

• Single cellular (w/a few multicellular)
• Have groups w/characteristics of other eukaryotic kingdoms
• Holding Kingdom

Question 11

Domain Eukarya: Kingdom Fungi

Answer 11

Cell- eukaryotic cell w/cell wall containing chitin
Nutrition-Heterotrophic-> Absorption
Motility- Nonmotile
Life cycle- Haplontic Life cycle
a) adult is haploid (n)
b) zygote is diploid (2n)
meiosis produces haploid spores; spores develop into adults

Energy- Glycogen

Question 12

Domain Eukarya: Kingdom Plantae

Answer 12

Cell- eukaryotic cell w/cell wall containing cellulose 
Nutrition- Autotrophic->photosynthesis
Motility- Nonmotile
Life cycle- Alteration of generations
Energy storage- starch

Question 13

Domain Eukarya: Kingdom Animalia

Answer 13

Cell- Eukaryotic cell lacking cell wall
Nutrition- Heterotrophic- Ingest food
Motility- motile- by contractile fibers-muscles
Life cycle- Diplontic-> Diploid adults (2n) that produce haploid gametes (n). Gametes are eggs or sperm
Energy storage-Glycogen
