Module 1.1 Prokaryote parts

Question 1

is a double layer of phospholipids with associated proteins and other molecules. It is essentially the “bag”that holds all of the intracellular material and regulates the movement of materials into and out of the cell.

Answer 1

Plasma Membrane

Question 2

This is the gel-like fluid that the cell is filled with, and is inside the plasma membrane. The cytoplasm is where all of the cellular organelles suspended within.

Answer 2

Cytoplasm

Question 3

Unlike eukaryotic cells, which has a cytoskeleton, prokaryotic cells such as the rod-shaped bacteria and archaea possess ___

This scaffolding provides structural support to the cell and plays a role in cell division

Answer 3

Cytoskeletal Proteins:

Question 4

These are the tiny protein-making machines that carry out the genetic instructions of the cell.

Answer 4

Ribosomes

Question 5

replacement of the nucleus

the region of the prokaryotic cytoplasm that contains the genome—the main genetic material (DNA) of the cell

typically have a single, circular chromosome

Answer 5

Nucleoid

Question 6

non-essential piece of DNA that confers an advantage

Answer 6

Plasmids:
