C Length of grapes stalks increases due to gibberellins. Gibberellins are responsible for elongation of stem leaf expansion, bolting, enzyme formation etc. Their ability to cause increase in length of axis is used to make stalk of grapes to grow larger and as certain better yield.

Internodal elongation is associated with
1 auxin
2 cytokinin
3 gibberellin
4 ABA
Explanation:
C Internodal elongation is associated with gibberellin. This properties is used in agriculture to the yield from sugarcane. It changes take place in the cells of internodal region increasing its length 3 to 4 times the original.

Which of the following growth hormones is associated with stomatal movements?
1 Auxin
2 Gibberellin
3 $\mathrm{ABA}$
4 Cytokinin
Explanation:
C ABA growth hormones is associated with stomatal movements. Application of exogenous ABA to leaves of normal plants causes closing of stomata within few minute. Stomata are tiny pores present on the surface of the leaves. Massive amount of gaseous exchanges take place in the leaves through these pores for the purpose of photosynthesis. But it is important to note here that the exchange of gases occurs across the surface of stems, roots, and leaves as well.

The most essential precursor of ethylene is
1 adenine
2 thiocarbamate
3 zearin
4 methionine
Explanation:
D The most essential precursor of ethylene is methionine for the plants to grow and reproduce they need sun, water minerals and other nutrients. Plant also relay an certain organic compounds to signal and monitor their growth. Ethylene is a plant hormone that is found in gaseous form in nature. It is primarily found in all dividing cells.
