Using the concept of osmosis, explain why the grapes placed in corn syrup changed. Be sure to explain how and why water moved?
Which solution has the greatest amount of sugar?
water
grape juice
corn syrup
Which type of solution has the least amount of sugar?
water
grape juice
corn syrup
A cell that is placed into an isotonic solution
swells in size
shrinks in size
stays the same size
A cell that is placed into a hypertonic solution
swells in size
shrinks in size
stays the same size
A cell that is placed into a hypotonic solution
swells in size
shrinks in size
stays the same size
Fill in the blank:
If a grape is placed into water than it will
shrink
swell
stay the same size
Fill in the blank:
If a grape is placed into grape juice than it will
shrink
swell
stay the same size
Fill in the blank:
If a grape is placed into corn syrup than it will
shrink
swell
stay the same size
The grapes placed in water
shrink
swelled
stayed the same
The grapes placed in grape juice
shrink
swelled
stayed the same
The grapes placed in corn syrup
shrink
swelled
stayed the same
After 24 hours in water
the mass increased
the mass decreased
the mass stayed the same
After 24 hours in grape juice
the mass increased
the mass decreased
the mass stayed the same
After 24 hours in corn syrup
the mass increased
the mass decreased
the mass stayed the same
