Initially, in terms of tonicity, the solution in side A with respect to that in side B is isotonic.
- A solution is considered to be isotonic if it possesses the same osmolarity, or level of solute concentration, as another solution. When these two solutions are placed on either side of a membrane that is only partially permeable to water, water will flow in an equal amount from one solution into the other. The result is that there is no water flow at all between the two solutions, despite the fact that water is travelling in both directions.
- A solution is considered hypotonic when it has a lower level of solute concentration in comparison to another solution.
- A solution is considered hypertonic when it has higher osmolarity compared to another solution.
In the given questions, the solution in the two arms of the U- tube has the same osmolarity and therefore is isotonic.

Explanation:
<em>The main difference between primary and secondary cell culture is that the primary cell culture contains the cells directly obtained from host tissue, whereas the secondary cell culture contains sub-cultured cells from primary cell culture.</em>

Explanation:
Typical roots contain three different sections, or zones: the meristematic zone, the zone of elongation, and the zone of differentiation. In the meristematic zone, named after the apical meristem, the plant cells undergo rapid mitotic division, creating new cells for root growth.
