Question 10

Internal Membranes are only found in ______’s organelles. (Eukaryotes or Prokaryotes)

Answer 10

Eukaryotes

Question 11

Describe the typical Eukaryote cell.

Answer 11

• DNA stored in nucleus
• with cytoskeleton
• genes with introns
• some with cell walls
• membrane-bound organelles

Question 12

Describe the membrane of Eukaryote cells.

Answer 12

Unbranched fatty acids

Question 13

What is symbiosis?

Answer 13

Interaction between 2 different organisms living in close physical association

Question 14

What is endosymbiosis?

Answer 14

Symbiosis in which one of the symbiotic organisms lives inside the other

Question 15

Which type of cell stays single cell organisms?

Answer 15

Prokaryotic cells

Question 16

Explain binary fission.

Answer 16

The chromosome is replicated and the 2 resulting copies separate from one another, due to the growth of the cell.
The Prokaryote is then pinched inward resulting in 2 cells (which are clones)
