Question

A 1cm diameter, 6 cm long core is removed from a carrot. The resulting hole is filled with corn syrup, and a glass tube is inserted into the hole to make a watertight seal. The carrot is suspended in a cup of pure water. Beginning with the carrot cells adjoining the hole, and going out to the carrot epidermal cells exposed to the water, describe what will happen to the carrot cells. Also, what will happen to the level of liquid in the glass tube and why?

■Here,The corn syrup is hypertonic to the carrot, so will take water from the adjoining cells, causing those cells to shrink, become hypertonic to their neighboring cells and to take water from them.

■Conversely the water is hypotonic, and will enter the cells in the outer of the carrot.

■Because of this water will pass from the outside of the carrot to the inside, and cause liquid in the tube to rise

Answer 2

Answer:

Carrot cell will swell and liquid level in glass will reduce

Explanation:

Carrot cell will absorb water and swell in due course of time as there is difference in concentration of water outside and inside the cell.  

Similarly, the corn syrup remains intact from the epidermal cell of the carrot due to the glass tube. Being hyper-tonic in nature and also due to presence of water tight glass lid, it is unable to extract water from the adjoining cell; corn syrup will take water from the tube thereby further reducing the level of water in the tube
