|
|
|
Because it has lag, log and stationary phase
|
|
|
Because one daughter cell remains meristematic while the other daughter cell differentiates and matures
|
|
|
Because of the effect of environment on mitosis

|
None

Detailed explanation-1: -In this growth, the rate of growth is constant. It is found in the root or shoots elongating at a constant rate. Linear curve is obtained in arithmetic growth, because one daughter cell remains meristematic while the other daughter cell differentiates and matures.
Detailed explanation-2: -This kind of curve is referred to as a growth curve or sigmoid growth curve.
Detailed explanation-3: -(a) Arithmetic growth: In arithmetic growth, one of the daughter cells continues to divide, while the other differentiates into maturity. The elongation of roots at a constant rate is an example of arithmetic growth.
Detailed explanation-4: -Mathematically arithmetic growth is expressed as Lt=L0+rt In this equation ‘r’ represents. No worries!
Detailed explanation-5: -Assertion: During arithmetic growth there is growth at constant rate. Reason: During arithmetic growth, after mitosis, both the daughter cells retain the capacity to divide continuously.
