4. The Calvin cycle takes place in which part of the chloroplast?

The correct answer is The Stroma.

Explanation:

The Calvin cycle is also known as the Calvin-Benson cycle or as the CO2 fixation phase in the photosynthesis process. This cycle consists of a series of biochemical processes that take place in the stroma that the chloroplasts of photosynthetic organisms possess.

It is known as the carbon cycle, and it is the name given to a cyclic chain of different chemical reactions that occur in the stroma of chloroplasts, which are responsible for forming carbohydrates after the fixation and reduction of carbon dioxide. In the Calvin cycle, carbon dioxide is assimilated and then ATP and NADPH from light reactions provide the energy needed to combine assimilated carbons to produce sugar.

(you didn't attach a copy of the poem, but i'm answering as best as i can)

since a simile compares two unlike things using like or as, it kind of gives an item the ability to do something it can't.

example: "the player was like a tiger on the field"

in this sentence, the simile conveys the idea that the player was fast and strong, like a tiger.
