Question

________ curve is obtained for cells in culture.

• A. J-shaped
• B. Linear
• C. V-shaped
• D. S-shaped

Answer 1

The correct option is D S-shaped

Plant growth rate be termed as the increase in growth per unit time. The rate of growth of a plant or plant part is not always uniform during its lifespan. Sometimes, it is slow and at other times rapid. If we plot the increase in cell number (growth rate) against time as in the case of cell culture (growing cells in a growth medium), a typical S-shaped curve is obtained.
