The photosynthetic reactions convert light energy into chemical energy, which is stored in molecules like atp. in the photosynthetic reactions, this energy is used to convert co2 into carbon sugars. a. light dependent; chloroplast b. chloroplast; light independent c. light dependent; light independent d. light independent; light dependent

Option C.light dependent; light independent

Explanation:

Photosynthesis is the process by which plants make there own food in the presence of sunlight by utilizing carbon-dioxide and water and produce energy in the form of glucose.

The photosynthesis process takes place in two sequential stages called light dependent reactions and light-independent reactions.

The light dependent reaction takes place in the grana, in which light is directly trapped from sun and make energy stored in the form ATP and water molecule split into oxygen, hydrogen ions and free electrons. these free electrons further reduced to NADPH fromnicotinamide adenine dinucleotide phosphate (NADP).

The light-independent reactions occurs in the stroma of the chloroplasts, where ATP and NADPH, are utilised and produces carbohydrates from carbon dioxide.

Hence, the correct option C.

six grader is what i am ssorry

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
