Where does the Calvin cycle occur? There is a scheme of the chloroplast structure. The outer layer of the chloroplast is labeled

A. The inner layer of the chloroplast membrane is labeled
B. A column of little cisterns is labeled
C. One of the cisterns is labeled
D. The space inside the chloroplast between its structures is labeled E.

A. The inner layer of the chloroplast membrane is labeled

Explanation:

Usually in plants, carbon dioxide enters the interior part of leaf through the pores also known as stomata and then diffuses into the stroma of the chloroplast.

Unlike the reactions to light, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma, also called the internal space of the chloroplasts, so it also takes place in the coroplast's storma.

The enzymes of Calvin Cycle responsible for cabon fixation( Ribulose Biphospahte Carbonxylase) Rubisco  is  located  in the STROMA, together with  sugar and inorganic acids. The stroma is the fluid  portion, of chloroplasts, located  in the inner membrane outside the thylakoid membrane  . Therefore option A -The inner layer of the chloroplast membrane is labeled.  is the correct answer.

It is a light independent reaction  which makes use of ATPs and  NADPH from the light dependent reaction to synthesize  Carbohydrate(glucose), amino acid and lipds.

Explanation:

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.

d. planting trees

the trees take in carbon to make oxygen.
