(ii) One daughter cell remains meristematic while the other one differentiates and matures.
(iii) Mathematical expression is `L_(t) = L_(0) +rt`.

B

statements (ii) and (iii) are correct

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
Increase in growth per unit time is called as growth rate. The growth rate may be arithmetic or gemoetrical. Arithmetic Growth is a type of growth in which the rate of growth is constant and increase in growth occurs in arithmetic progression -2,4,6,8,10,12. Meristematic cells at the growing point divide in such a fashion that one daugther cell remains meristematic while the other grows and differentiates. the process continues. Mathematically, arithmetic growth is expressed as
`L_(t) = L_(0) + rt`
where `L_(t) =` length after time `t,L_(0) =` length ath the begining, and `r=` growth rate. on plotting growth aganist time, a linear curve is obtained.
