Question

(a) Name the two factors on which the shape of the cell depends.
(b) A student put 3 raisins each in two beakers A and B. Beaker A contains
50ml of distilled water and beaker B has 50 ml of saturated sugar
solution.what changes would he observe after some time?​

Answer 1

Explanation:

The shape of the cells depends upon the different functions they perform. They may be sperical, rounded, cuboidal, tubular, discoidal or irregular. It also depends on the cytoskeleton.

Raisins in the beaker A will swell as solution surrounding them is hypotonic in nature. Hypotonic solution contains lesser solute concentration. In such case, endosmosis will occur in which inward movement of the water molecules from the lower solute concentration to higher solute concentration through raisin covering.

Raisins in the beaker B will shrink as solution surrounding them is hypertonic in nature. Hypertonic solution contains higher solute concentration. In such case, exosmosis will occur in which outward movement of the water molecules from the lower solute concentration to higher solute concentration through raisin covering.
