Anil Ahlawat Solutions for Chapter: Cell-The Fundamental Unit of Life, Exercise 1: EXERCISES

Take a clean glass slide and put few drops of water on it. Now place a complete Rheo leaf on water droplets and examine the cells of leaf under the high power of compound microscope. Put a few drops of concentrated salt/sugar solution on the mounted Rheo leaf on the glass slide. Wait for few minutes and again observe the leaf under the high power of microscope.
What will be your observation after few minutes?

Which of the following is correct for the given figure ?

Select the incorrect statement.

Among the following cell organelles $P,Q,R$, and $S$, which is the odd one out?

Four strips are cut from a fresh potato. The length of each strip is measured. One strip is placed in water and others in different concentrations of sugar solution. After an hour, the strips were measured again. The results are shown in the table. Which of the liquids $P,Q,R$ and $S$ is water?

A unicellular protist $X$, which has contractile vacuole to remove excess intracellular water, was placed in salt solution of increasing osmolarity. The given graph shows the rate of contraction of vacuole to pump out excess water against osmolarity of solution.

Select the option that gives the correct explanation of the data.
