2.6 Prokaryotic Cell Structure

Question 1

Prokaryotic organisms are always:

Answer 1

a single-celled organism due to having few organelles and non-membrane bound organelles

Question 2

DNA in Prokaryotic Cells

Answer 2

the structure of DNA in prokaryotic and eukaryotic cells are the same however prokaryotic cells do not have nuclei and so their DNA is free floating in the cytoplasm

Question 3

Ribosomes in Prokaryotic Cells

Answer 3

the ribosomes found in these cells are smaller than those found in eukaryotic cells, they are 70S ribosomes so form simpler proteins than eukaryotic cells

Question 4

Cell Walls in Prokaryotic Cells

Answer 4

this cell wall differs from those in plant cells as this cell wall is made from peptidoglycan, AKA murein
it is a polymer made from amino acids and sugars

Question 5

Flagella in Prokaryotic Cells

Answer 5

Thinner and lacks the 9+2 arrangement that eukaryotic cells have
the energy supplied to rotate the appendage comes from the process of chemiosmosis

Question 6

What are the differences between Prokaryotic Cells and Eukaryotic Cells?

Answer 6

Eukaryotic Cells contain a nucleus and membrane-bound organelles, while Prokaryotic Cells do not.
The ribosomes in Eukaryotic Cells are also large than those in Prokaryotic Cells
