Statement \(A\) : Shape of the cell is variable with the function they perform. Statement B: Neuron cell is longest and branched animal cell that sends and receives signal from brain.
1 \(A\) is false, \(B\) is true
2 Both A and B are false
3 \(A\) is true, \(B\) is false
4 Both A and B are true
Explanation:
D There is great variability in cell shape ie, spherical, polygonal, disc-like cuboidal, columnar, spindle-like, etc. The shape of the cell may vary with the function they perform e.g. Xylem vessels are long as they have to form long water conducting channels. Nerve cells are long and branched.

When a cell of diameter \(2 \mu \mathrm{m}\) grows to double its diameter, what will happen to its surface area volume relationship?
1 It will remain the same
2 It will reduce to half
3 It will double
4 It can not be determined
Explanation:
B Initial & Final \(\mathrm{d}=2 \mu \mathrm{m}\) & \(\mathrm{d}=4 \mu \mathrm{m}\) \\ so \(\mathrm{r}=1 \mu \mathrm{m}\) & \(\mathrm{r}=2 \mu \mathrm{m}\) \\ Surface area \(=4 \pi(1)^{2}\) & \(\mathrm{SA}=4 \pi(2)^{2}\) \end{tabular} \(\begin{array}{ll}\text { Volume }=\frac{4}{3} \pi(1)^{3} & \text { Volume }=\frac{4}{3} \pi(2)^{3} \\ \frac{\mathrm{SA}}{\mathrm{V}}=\frac{4 \pi \times 1}{\frac{4}{3} \pi \times 1}=3: 1 & \therefore \frac{\mathrm{SA}}{\mathrm{V}}=\frac{4 \pi \times 4}{\frac{4}{3} \pi \times 8}=3: 2\end{array}\) Hence, the surface area volume relationship will reduce half.

The term protoplasm for the cell contents was coined by
1 Von Mohl
2 J.E. Purkinje
3 J.S. Huxley and Hertwig
4 M. Schultz
Explanation:
B J.E Purkinje used term protoplasm in plant cells. - M.Schultze proposed protoplasmic theory. - Von Mohl given the importance of the protoplasm in plant cell. - Huxley explained protoplasm is the physical basis of life in energy generated of the protoplasm.

Explanation:
B Aerobic respiration occurs in the mitochondria and productin of ATP therefore mitochondria is called power house of cell. Mitochondrial DNA replication is initiated at \((\mathrm{OH})\) strand and proceeds. Unidirectionally to produce the full length nascent it strand. Carbohydrates assimilate in chloroplast during the day with some stored as starch or degraded to supply sugars for growth at night. Most chloroplast proteins are synthesized in the cytoplasm imported and then targeted to a specific chloroplast compartment. Chloroplasts are specialized to perform photosynthesis.
