Explanation:
Answer is A. Calvin cycle.
Calvin cycle reactions or light independent process of photosynthesis occurs in the stroma (Ground substance) of the chloroplast. In the stroma enzymes are present for the Calvin cycle reactions. Carbon dioxide (CO₂) enters into the leaves through stomata and diffuses into stroma of the chloroplast. In the stroma carbon atoms from CO₂ is fixed into sugar (carbohydrate) with the help of energy from ATP and NADPH.

D.

Answer:
- <u>cell;</u> <u>prophase</u>. <u>prometaphase</u>
- <u>metaphase. anaphase,</u> t<u>elophase.</u>
Explanation:
Mitosis is the division of the <u>cell</u><u> </u>and begins with a stage called <u>prophase</u>. As the nuclear envelope finishes dissolving, the cells enter <u>prometaphase,</u> where microtubules from the spindle attach to the duplicated X-shaped chromosomes.
When all chromosomes are fully attached to the spindle, they align at the midplate between poles. This marks the middle of mitosis, which is <u>metaphase</u>. As sister chromatids separate, cells enter <u>anaphase</u> and they finish separating, and a nucleus reforms around each set of new chromosomes in telophase. During this phase, cytokinesis also becomes visible as the cells themselves begin to divide.
