Thylakoids are the parts of a chloroplast that holds a. stroma. b. chlorophyll. c. nucleoli. d. none of the above i think its either a or b

 Option B  

Explanation:

Thylakoids are membrane bound compartments inside cyanobacteria  and chloroplast. They are the main site for the process of photosynthesis.

The chlorophyll present in thylakoids absorbs sunlight and converts light energy into chemical energy.

This energy is used by plants to get energy to carry the various metabolic processes of the plant body.

Thus, the correct answer is option A

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
