Question 4

Which process allows water to move across a partially permeable membrane from a dilute to a concentrated solution?

Accepted Answer

Osmosis

Answer

Osmosis is the movement of water molecules through a partially permeable membrane down a water potential gradient.

Question 5

What is the role of ribosomes in a cell?
