Cellular Transport Test Review

How would you tell from a picture if a cell is a prokaryote or eukaryote?

• Presence of a nucleus indicates a eukaryotic cell, while absence of a nucleus indicates a prokaryotic cell.
• The shape of the cell membrane determines if it is prokaryotic or eukaryotic
• The color of the cell under a microscope indicates if it is prokaryotic or eukaryotic
• The size of the cell determines if it is prokaryotic or eukaryotic

What in picture 1 indicates this is active transport other than the ATP?

• The molecules are moving through a protein

• The molecules are moving into the cell

• The molecules are moving from low concentration to high concentration

• The molecules are larger than what can move through the membrane

Which type of transport is picture 2 representing?

• Diffusion

• Facilitated Diffusion

• Osmosis

• Active Transport

What cell has a plasma membrane, circular DNA and a cell wall?

• Plant cell

• Animal cell

• Eukaryote cell

• Prokaryote cell

Salt water solution would make a cell ​ (a)   as it ​ (b)   water.

• shrink
• loses
• swell
• gains
• not change
• does not gain/lose

Hypotonic solutions make cells

• Shrink

• Swell

• Not Change

The movement of water across the membrane is known as

• Diffusion

• Facilitated Diffusion

• Osmosis

• Active Transport

What would happen to a freshwater protozoan if it were placed in a tank of salt water?

• It would lose water through active transport

• It would lose water through osmosis

• It would become larger and healthier
• It would thrive and reproduce rapidly

ATP energy is used to move molecules

• With the concentration gradient

• Against the concentration gradient

• of water into or out of the cell

• that replace damaged phospholipids

These are samples that a scientist viewed under a microscope. Match the sample to the type of solution it was placed in?

• Hypertonic

• Sample 4

• Isotonic

• Sample 2/3

• Hypotonic

• Sample 1
