(a) growth of plants
(b) delaying fruit’s abscission
(c) ripening of fruits
(d) stopping the leaf abscission

Answer 1

Answer:

answer is option c

Explanation:

because ethylene is used in ripening of fruits

Answer 2

Option C

Ethylene gas is used for ripening of fruits

Explanation:

• Ethylene is a simplistic gaseous plant growth regulator (PGR).
• It is amalgamated in huge quantities by tissues bearing senescence and ripening fruits.
• Impacts of ethylene on plants incorporate horizontal germination of seedlings, swelling of the support and apical tool development in dicot seedlings.
• Ethylene elevates senescence and abscission of plant organs, particularly of leaves and flowers.
• Ethylene is extremely productive in fruit ripening. It intensifies the respiration rate when the ripening of the fruits.
• This acceleration in the frequency of respiration is designated as respiratory climacteric.
