DNA contains a vast amount of hereditary information and is responsible for the inheritable

characteristics of living organisms. RNA is responsible for deciphering the hereditary information in DNA

and using it to synthesize proteins.


What is the plasma membrane and what is it made of? - Ans:✔✔-The plasma membrane serves the cell

as a surrounding barrier that separates the inside of the cell from the outside surrounding environment.

The plasma membrane also restricts the movement of materials (water, nutrients, etc) either in or out of

(out flux) of essential nutrients. The plasma membrane is composed of lipids (hydrophobic

hydrocarbons).


What are the three main components of carbohydrates? - Ans:✔✔-carbon, hydrogen, oxygen


What is the primary difference between prokaryotic and eukaryotic cells? - Ans:✔✔-Eukaryotic cells

contain a nucleus, a membrane enclosed region within the cell that contains the genetic material.

Prokaryotic cells do not have a nucleus and can be further classified as either Bacteria or Archaea.


What are the main morphologies of bacteria? - Ans:✔✔-coccus (round/spherical), bacillus (rod), vibrio

(curved rod) or spirillum (spiral/corkscrew)

What do eukaryotic cell membranes have that prokaryotic cell membranes don't? - Ans:✔✔-sterol lipids

(ex: cholesterol)


Functions of plasma membrane? - Ans:✔✔-Proteins in membrane allow the import of nutrients or
