Question

Two peeled large carrot pieces are placed in beakers, one containing water and other containing saturated sugar/salt solution. The carrot pieces are observed after 6-8 hours.

Answer 1

1. The carrot that is placed in the beaker containing water will increase in size due to movement of water inside (endosmosis). The carrot placed in saturated salt solution will shrink in its size due to exosmosis.
2. The process involved that has caused such a change is osmosis.
3. Osmosis helps the  plant cells keep rigid by creating enough pressure against the cell wall. Thus, plant cells can absorb water via osmosis without danger of bursting. Also, the process occurred to balance the concentration of solute on both the sides .

Answer 2

Answer:

a)Difference in physical state observed:

The difference between the two carrots is that the carrot in the plain water appears bigger or slightly swollen while the carrot in the salt water appears smaller and has shrank in length and slightly in width.

b)Process involved that has caused the changes:

The process that has taken place is osmosis.

c)Why has the process occured:

The process occurs due to the semi-permeable membrane of the cells of carrots that allow water either in or out of the cells.

In the plain water, the process that takes place is endosmosis where the cells of the carrot draw in water and hence the carrot increases in mass. The carrot in the salt water, on the other hand, experiences exosmosis, where water is drawn from the carrot's cells and the carrot becomes dehydrated and shrinks in length and width.
