Question

5. Where do the light and dark reactions take place?
6. How much of the photosynthesis on the biosphere occur in oceans/seas?
7. Where are the photosynthetic pigments located in a chloroplast?
8. How do submerged aquatic plants get carbon dioxide?​

Answer 1

Answer:

5. Light reaction in grana of the chloroplast.

and dark in stroma of the chloroplast.

6. Approximately 50%

7. Thylakoid Membrane

Explanation:

8. In aquatic plants or plants that live in water use carbon dioxide gas dissolved in water for carrying out photosynthesis. So, we can say that stomata pores allow the movement of gases in and out of plant cells. Therefore, the gaseous exchange in plants takes place through the stomata in leaves and other green parts.
