Biology cell transport

Why will a plant die if you water it with a salt water?

• hypotonic solution
• hypertonic solution
• isotonic solution
• silly solution

Humans shiver when they are cold to maintain

• cytolysis
• turgor pressure
• limbo
• homeostasis

If the sodium concentration inside a cell is greater than outside the cell, how can a cell take in more sodium?

• osmosis
• diffusion
• active transport
• passive transport

Which is an example of how humans maintain homeostasis in bad environmental conditions?

• sweating in the heat
• shivering in the heat
• digesting amino acids
• regulating glucose levels

All living things want to remain in...

• chaos
• homeostasis
• limbo
• plasmolysis

Which process involves the movement of molecules from high concentration to low concentration?

• Endocytosis
• Active transport
• osmosis
• phagocytosis

if you put a plant in salt water it will ...

• swell because water diffuses into the cells
• swell because water diffuses out of the cell
• shrivel because water diffuses out of the cell

Two different solutions are separated by a membrane permeable only to water. How will molecules move?

• solutes will move by dissolving
• water will move by active transport
• solutes will move by osmosis
• water will move by osmosis

A cell in an isotonic solution will

• swell
• shrink
• stay the same size
• impossible to tell

A cell in a hypotonic solution will

• swell
• shrink 
• stay the same size
• impossible to tell
