In eukaryotes, all the reactions of photosynthesis occur in various membranes and compartments of the chloroplast. a. True
b. False

The correct answer is - a. true.

Explanation:

The chloroplast is surrounded by inner and outer membranes. These membranes help in separating the inner compartments and structures from the cytosol Inside the chloroplast. These various membranes and compartments play various roles during photosynthesis.

For instance;

a) stroma- the Calvin cycle takes place in the stroma

b) thylakoid membrane - the light reactions takes place here

c) envelope membranes- the inner and outer membranes of the chloroplast

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
