Auxin is the molecule which is related to the phototropism of the plants. In the mutant plants, which do not have hormone auxin, do not respond to light. It activates proton pump, and leads to the decrease in the pH of the leaf. This acidification breaks cell wall structure and cell wall become less rigid, and thus, can bend towards the light, by exerting mechanical pressure.

Answer:
rhizobia is an important nitrogen fixing bacteria found in the soil to help grwo plants like legumes. rhizobia enter into a symbiotic relationship withe legumes
Explanation:
rhizobia and legumes coexist by entering into a symbiotic association. rhizobia is a bacteria that fixes nitrogen molecules for the legumes and in return the legumes provide the bacteria with food and nutrition.
If rhizobia becomes extinct in the near future it would be difficult for plants like legumes to grow as they wouldn't get sufficient nitrogen and nitrogen is an important nutrition for the plant to grow and develop. Thus it can cause rapid depletion or death of plants that need rhizobia to fix nitrogen molecules for them.
Answer:
Diploid.
Explanation:
DNA is present in the genetic material of all the eukaryotic and prokaryotic organisms.The eukaryotic genome contains DNA wraps around the histone proteins. Multiple distinct chromosomes are present in the eukaryote genome.
The eukaryotic genome are generally linear structure with the two copies of each chromosome. This makes the eukaryotic genome as diploid structure.
Thus, the correct answer is option (1).
