Question

1. Activity: Cut two pieces of potato to 5 cm. Add one piece into the sugar solution and the other into the water. Based on your observation , write the following
A. Make a prediction about what will happen to the size of the two pieces of potato after a period of time.
B. Explain your prediction about the transport taking place in the activity.
C. What type of transport is this?
D. Is this a passive or active transport , Explain Why?
E. Active transport is the movement of the substance from an area of ______concentration to an area of __________ concentration across a _________permeable _________ . It requires _____to take place

Answer 1

A) After a period of time, the piece of potato that was dipped in sugar solution it will become more or less flexible as potato already contains sugar, and less water will be diffused inside.

B) Osmosis, as well as diffusion, will take place. The part of the potato that was placed in after will turn rigid as it will absorb water.

C) This transportation is known as diffusion & well as osmosis.

D) This is passive transportation as no external energy is needed.

E) Active transport is the movement of the substance from an area of higher concentration to an area of lower concentration across a semi-permeable membrane. It requires Osmosis to take place.

Answer 2

1) After a period of time, the potato piece will turn flexible.

2) Osmosis and diffusion will take place. The potato piece placed on water will turn rigid.

3) This transportation is known as diffusion or osmosis.

4) Passive Transportation.

5) Active transportation is the movement of water from the region of higher to lower concentration across a semipermeable membrane.
