1. Plasmolysis in a plant cell is defined as
(a) shrinkage of nucleoplasm
(b) shrinkage of cytoplasm in hypertonic solution
(c) break down of plasma membrane in hypotonic solution
(d) shrinkage of nucleolus
2. Choose the correct statement of the following.
(a) Conversion of solid into vapours without passing through the liquid state is called vaporisation.
(b) Conversion of solid into vapour without passing through the liquid state is called sublimation.
(c) Conversion of vapours into solid without passing through the liquid state is called freezing.
(d) Conversion of solid into liquid is called sublimation.
3. The smooth muscle consists of _______________. Each fibre contains a single oval nucleus in its
thick middle part. The cross-striations are absent so that the fibres look smooth, hence the name
unstriated.

(a) Diffusion (b) Transpiration (c) Osmosis (d) Evaporation
6. When sound gets reflected from a surface:
(a) The angle of reflection is always greater than the angle of incidence.
(b) The angle of reflection is always less than the angle of incidence.
(c) The angle of reflection is always equal to the angle of incidence.
(d) The angle of reflection is always equal to 90°.
