BIOXI15: PLANT GROWTH AND DEVELOPMENT

337993 The gaseous plant growth regulator is used in plants to

1 promote root growth and root hair formation to increase the absorption surface
2 help overcome apical dominance
3 kill dicotyledonous weeds in the fields
4 speed up the malting process
BIOXI15: PLANT GROWTH AND DEVELOPMENT

337994 Apples are generally wrapped in waxed paper to

1 Prevent sunlight for changing its colour
2 Prevent aerobic respiration by checking the entry of \(\mathrm{O}_{2}\)
3 Prevent ethylene formation due to injury
4 Make the apples look attractive
BIOXI15: PLANT GROWTH AND DEVELOPMENT

337995 Ethylene is used for

1 Retarding ripening of tomatoes
2 Hastening of ripening of fruits
3 Slowing down ripening of apples
4 Both 2 and 3
BIOXI15: PLANT GROWTH AND DEVELOPMENT

337981 Statement A :
Ethylene is synthesised in large amounts by tissues undergoing senescence and ripening fruits.
Statement B :
Influences of ethylene on plants include vertical growth of seedlings, swelling of the axis and axial hook formation in monocot seedlings.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
