Question

Difference between arithmetic and geometric growth

Answer 1

ARITHMETIC GROWTH
In arithmetic growth only one daughter cells dives and all the other cells undergo differentiation and maturation.

The graph obtained is a linear one.

Ex: Elongation of root occurring at a constant rate.

GEOMETRIC GROWTH

In geometric growth the growth is proportional to the nutrients supply after which it declines. All the daughter cells divide by mitosis. This is also known as exponential growth.

Represented by a sigmoid curve where the three phases are initial, exponential and stationary phases.

Ex; Cells growing in a culture medium.

hope it would help;-)

Answer 2

Ans: the increased growth per unit time is termed as growth rate.

Type of growth rate are:

Arithmetic and geometric

1 arithmetic growth is that only one daughter cell continue to divide while the other differentiates and matures.

2 it increases rapidly means one daughter cell convert in two daughters cell and they can continue divide in two daughters cell.
