Review Up to Photosynthesis/Cell Resp

Which statement best describes the cell membrane?

• The protective outer layer that controls what enters and leaves the cell.
  
• Stores information on DNA molecules / Directs and controls the activities of the cell.
  
• A folded membrane that moves materials around inside cells / Also acts as the site of manufacturing materials needed by the cell.
  
• The smallest organelle with a huge job / Makes proteins, which are the building blocks of the body.

What does a cell need in order to transport particles by active transport?

• Glucose

• Vesicles

• Energy

• Channels

What is one major difference between passive and active transport?

• Passive transport uses energy; active transport does not.
• Both types of transport use energy.
• Active transport uses energy; passive transport does not.
• No difference. They are both the same.

What characteristic defines this organism as prokaryotic?

• Ability to move
• Ability to respond
• Shape and size
• Lacking of membrane-bound organelles

What structures are found in ALL prokaryotic AND Eukaryotic Cells?

• flattened, stack-like structures which process macromolecules.
• a continuous, interconnected network of membranes.
• small, protein -producing units composed of RNA and protein.
• Power-producing organelles that convert energy into usable forms.

Which structures are found in plant cells, but not in animal cells?

• Cell membranes and mitochondria
• Vacuoles and cholorplasts
• Cell walls and cytoplasm
• Chloroplasts and cell walls
