Question

1. complete the following chart below about the three types of osmosis, which is the movement of water molecules across the cell membrane that does not require energy. (slides 11 - 15)

osmosis ****movement of water

hypotonic solution hypertonic solution isotonic solution

definition

where does the water travel?

result

Explanation:

A hypotonic solution has a lower solute concentration than the cell. Water travels into the cell, causing it to swell or lyse. A hypertonic solution has a higher solute concentration than the cell. Water travels out of the cell, causing it to shrink or crenate. An isotonic solution has the same solute concentration as the cell. There is no net movement of water, and the cell maintains its shape.

Answer:

	Hypotonic Solution	Hypertonic Solution	Isotonic Solution
Where does the water travel?	Into the cell	Out of the cell	No net movement
Result	Cell swells/lyses	Cell shrinks/crenates	Cell maintains shape
Picture	As shown (cells appear swollen)	As shown (cells appear shriveled)	As shown (cells normal - shaped)
