Question 1

What are the 3 domains that classify life?

Answer 1

Archaea, Bacteria, and Eukarya

Question 2

Characteristics of Archaea and Bacteria?

Answer 2

Small, mostly unicellular organisms that possess circular DNA, replicate by fission, and lack membrane-bound organelles

Question 3

Characteristics of Eukaryotes?

Answer 3

Unicellular or multicellular
Possess linear DNA
replicate by mitotic and meiotic division
Possess membrane- bound organelles like nuclei, cytocskeletal, and mitochondria

Question 4

How did chloroplasts evolve?

Answer 4

Engulfment of an ancestral photosynthetic bacterium by a eukaryotic cell- it lived and multiplied inside of the cell

Question 5

What is a chloroplast?

Answer 5

Specialized photosynthetic organelles in eukaryotes that have pigment-containing thylaklid membranes

Question 6

What is symbiosis?

Answer 6

2 species living together in close contact

Question 7

What are green plants?

Answer 7

Aquatic green algae and embryophytes (land plants)

Question 8

Land plant characteristics?

Answer 8

-Outer cuticle which protects tissues from desication
-specialized egg and sperm producing organs with outer layer of protective cells
- intercalated diplodocus phase in life cycle - termed embryo
