Part of the plant where photosynthesis generally occurs

Leaves

Explanation:

Photosynthesis takes place in things called chloroplasts. Chloroplasts contain a green substance called chlorophyll. Most of these can be found in the leaves of the plant.

Photosynthesis can take place in leaves, stem (green part of plant which containing chlorophyll) but mostly it takes place in leaves .

Chromoplasts(coloured plastids) containing chlorophyll are known as chloroplasts. Chloroplasts are important for photosynthesis in plants . They also contain yellow and orange pigments in addition to chlorophyll(green pigment).

answer is a

explanation:

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.
