prokaryotic vs eukaryotic?

Question

Which of the following comparisons between prokaryotic and eukaryotic cells is incorrect?

a. The lack of organelle in prokaryotes means that they are structurally less complex than eukaryotes.
b. The lack of internal membranes means that prokaryotes cannot compartmentalize function to the same extent as eukaryotes.
c. All membrane function in prokaryotes is accomplished in the plama membrane, while in eukaryotes, these functions are more distribted among the organelles.
d. The specialization of function in organelles suggests that eukaryotes will contain a wider variety of phospholipids than prokaryotes
e. The lack of organelles in prokaryotes means that the basic cellular functions are different in prokaryotes than in eukaryotes.

Answer 1

A B C and E are all correct.

Leaving you with D. The phospholipids do not vary at all. Each has a phosphate 'tail' which is hydrophobic (water-hating) and a 'head' which is hydrophilic. They arrange themselves in a bilayer, with the hydrophobic tail pointing inwards.

Answer 2

Prokaryotic cells only have cell walls... Think : Prokaryotic Cells are Plant Cells and Eukaryotic are Animal Cells :) hope i helped

Answer 3

I'd pick D. Phospholipids are the same in all kinds of membranes.

Answer 4

D.
