A phytohormone, which increases the production of starch hydrolyzing enzymes during the germination of maize seeds, is employed for the following
Production of malt
Delayed ripening of fruits
Promoting bolting in beet
Thinning of cotton, cherry and walnut
In geometrical growth, lag phase is represented by
Initial rapid growth
Latter rapid growth
Initial slow growth
Latter slow growth
Water is required in plant growth for
Enzymatic reactions
Cell enlargement
Extension growth
All of these
Arithmetic growth is linear because
One daughter cell remains meristematic and other differentiates and mature
Both daughter cell remains meristematic
Both daughter cells gets matured
All of the above

Lag phase
Steady phase
Log phase
All of these
Which one is an example of redifferentiation?
Cork cambium
Secondary cortex
Meristems
Interfasicular cambium
Plant growth regulators are also described as
Plant growth substance
Plant hormones
Phytohormones
All of these
Exponential growth can’t be sustained for much time due to
I. limited space and nutrient
II. accumulation of toxic agent
III. unlimited space and nutrient
IV. accumulation of nutrient agent
Choose the correct combination of options

III and IV
Opening of floral buds into flowers, is a type of
Autonomic movement of locomotion
Autonomic movement of variation
Paratonic movement of growth
Autonomic movement of growth
The type of growth where new cells are always being added to plant body by the activity of meristem is called
Closed form of growth
Diffused form of growth
Open form of growth
Discontinuous form of growth
