If we were to compare the cells in the plant leaves to the cells in the plant roots, we would expect the leaf cells to contain many more a) chloroplasts. b) leucoplasts. c) nuclei. d) ribosomes.

Chloroplasts because that is the substance that gives leaves its green colour and also helps in photosynthesis

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
