Read the scenario below.

You receive a bouquet of flowers and want to make them last as long as possible.

Which plant hormones could be used to address this situation?

ethylene

gibberellins

cytokinins

auxins

Auxins

Explanation:

Auxins are plant hormones with several roles one of which is delaying (inhibiting) abscission of leaves or flowers. This is done by applying auxin to the flowers, since young flowers have been known to consist of high auxin content that however lowers as it ages.

Thus, applying auxin to the bouquet of flowers would make them last as long as possible

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
