Geometric Growth

Q. Zygote exhibits growth which is represented by a sigmoid growth curve.

1. arithmetic
2. geometric
3. logarithmic

Q. The following data were obtained from an experiment on 2 plant samples showing exponential growth: $\begin{array}{cccc}\text{Sample}& \text{Initial weight}& \text{Final weight (in grams)}& \text{Time of growth(in}\\ & \text{grams)}& & \text{seconds)}\\ \text{A}& 107& 321& 15\\ \text{B}& 723& 1446& 16\end{array}$
Can you determine which sample is growing faster?

1. A
2. B
3. They are growing at equal rates
4. Cannot be determined

Q. Geometric growth is seen in

1. zygote during embryogenesis.
2. explant in tissue culture.
3. bacteria in rich nutrient culture.
4. meristematic cells in root tip.
