Answer 1

prokaryotic cells

Question 2

Give the 4 organelles present in both prokaryotic and eukaryotic cells.

Answer 2

• plasma membrane
• cytosol
• DNA
• ribosomes

Question 3

TRUE or FALSE:
The primary difference between prokaryotic and eukaryotic cells is the location of the DNA.

Answer 3

True

Question 4

Which organelle refers to the attachment structures on the surface of prokaryotic cells?

Answer 4

fimbriae

Question 5

It refers to the region where the prokaryotic cell’s DNA is concentrated.

Answer 5

nucleoid

Question 6

It refers to the outer coating of prokaryotic cells consisting of a capsule or a slime layer.

Answer 6

glycocalyx

Question 7

Give the etymology and the meaning of the term eukaryotic.

Answer 7

Eukaryotic means “true nucleus.” It comes from the Greek words “eu” which means true and “karyon” which means kernel (referring to the nucleus).

Some prokaryotic cells possess regions surrounded by proteins (not membranes) within which specific reactions occur.

Answer 8

True

Question 9

It refers to the thin projections on the surface of intestinal cells which increases the surface area of the cell without an appreciable increase in volume.

Answer 9

microvilli

Question 10

TRUE or FALSE:
The plasma membrane and organelle membranes participate directly in the cell’s metabolism because enzymes are built right into the membrane.

Answer 10

True
