biology help....!!!?

Question

i need help with one biology question that i got wrong. please help me because the test is tomorrow!!!

1) How does nitrogen-fixing bacteria benefit plants?

this is what my answer was: the plant provides the bacteria with a home airtight, swelling on its roots and supples them with carbohydrates.

please help me with this.

one more thing, my teacher likes the answers to be 2-3 sentences maximum, so if you can, please make it 1-3 sentences. THANK YOU!!

Answer 1

You answered the question kind of backwards because you're thinking of what the plant does for the bacteria. The question asks what the bacteria do for plants.

Nitrogen-fixing bacteria take nitrogen gas from the air and make it into a nitrogen compound that plants can use. Plants cannot use nitrogen gas directly from the air.

Answer 2

Hey.... Your answer is right opposite to what they have asked.
Well... Here is your answer in a couple of sentences:

The nitrogen fixing bacteria (nitrosomonas and nitrobacter) in roots of leguminous plants trap atmospheric nitrogen to the soil. This nitrogen, fixed by the bacteria serves as a nutrient to the plants.

Answer 3

1. The nitrogen-fixing bacteria fix atmospheric nitrogen into forms that plants, which can't fix their own nitrogen from the atmosphere, can use. Plants use the fixed nitrogen to synthesize amino acids and the nitrogenous bases of DNA and RNA, among other things.

Answer 4

The bacteria convert the free nitrogen in air into nitrogen compounds and fix the in the roots of legume plants. this is how the cycle occurs.
nitrogen is converted into protoplasm in plants which is converted into ammonia by the process of ammonification. the nitrosomonas bac convert it into nitrites. then the nitrobacter converts it into nitrates. then by the process of denitrification it is converted back into nitrogen.

hope i helped u
good luck for ur test
