1 The increased growth perunit time is termed as growth rate.
2 Growth is expressed in increase in cell number.
3 Arithmatic growth rate plot a linear curve and it expressed as \(L_t=L_0-r t\).
4 Geometrical growth rate plot a curve is sigmoid and expressed as \(W_1=W_0 e^{r t}\).
Explanation:
The growth rate in arithmatic growth plot a linear curve and it expressed as \(L_t=L_0+r t\).
\(\mathrm{L}_{\mathrm{t}}=\mathrm{L}_0+\mathrm{rt}\)
\(\mathrm{L}_{\mathrm{t}}=\) length at time ' \(\mathrm{t}\) '
\(\mathrm{L}_0=\) length at time 'zero'
\(r=\) growth rate / elongation per unit time.

Environmental heterophylly is see in :
1 Cotton
2 Coriander
3 Larkspur
4 Buttercup
Explanation:
Enviromental heterophylly is the difference in shapes of leaves due to different enviromental conditions. Buttercup represents the hetercophyllous development due to different environment conditions.

\(\mathbf{N}^6\) - furfurylamino purine is :
1 Guanine derivative
2 Adenine derivative
3 A stress hormone
4 A terpene
Explanation:
PGRs could be indole compounds (indole-3-acetic acid, IAA); adenine derivatives ( \(\mathrm{N}^6\)-furfurylamino purine, kinetin), derivatives of carotenoids (abscisic acid, ABA); terpenes (gibberellic acid, \(\mathrm{GA}_3\) ) or gases (ethylene, \(\mathrm{C}_2 \mathrm{H}_4\) ).

Which is incorrect for gibberelin :
1 Gibberellin reported only from fungus
2 Denoted as \(\mathrm{GA}_1, \mathrm{GA}_2, \mathrm{GA}_3\)
3 All gibberellin are acidic
4 Gibberellin promote fruit on tree longer to extend the market period
Explanation:
Gibberellins, cause fruits like apple to elongate and improve its shape. They also delay senescence. Thus, the fruits can be left on the tree longer so as to extend the market period. All gibbernllins are acidic in nature.
