• A. living organism growing in a natural environment
• B. typically all cells, tissues and organs of a plant
• C. root elongation at a constant rate
• D. both (a) and (b)

Answer 1

Answer: (C)

Arithmetic growth is a type of growth in which the rate of growth is constant and increase in growth occurs in arithmetic progression. It is found in root or shoot elongating at constant rate. Arithmetic growth is expressed
$L_t=L_o+rt$
where $L_t=$ Length after time $t$
$L_0=$ Length at the beginning
$r=$ Growth rate.
