this section explains what happens inside chloroplasts during the process of
photosynthesis.
inside a chloroplast

1. chloroplasts contain saclike photosynthetic membranes called
2. what is a granum?
3. the region outside the thylakoid membranes in the chloroplasts is called the
4. what are the two stages of photosynthesis called?

a.
b.

1. complete the illustration of the overview of photosynthesis by writing the products

and the reactants of the process, as well as the energy source that excites the electrons.

Explanation:

1. Thylakoids are the sac - like photosynthetic membranes in chloroplasts.
2. A granum is a stack of thylakoids.
3. The region outside the thylakoid membranes in chloroplasts is called the stroma.
4. The two stages of photosynthesis are the light - dependent reactions and the Calvin cycle (light - independent reactions).
5. Reactants: \(CO_2\) (from the Calvin cycle input, also water which is not shown in this partial diagram but is a reactant in light - dependent reactions), energy source: sunlight (excites electrons in light - dependent reactions), products: \(O_2\) (from light - dependent reactions) and glucose (from the Calvin cycle, though not fully shown in this diagram, generally a product of photosynthesis).

Answer:

1. Thylakoids
2. A stack of thylakoids
3. Stroma
4. a. Light - dependent reactions; b. Calvin cycle (light - independent reactions)
5. Reactants: \(CO_2\) (and \(H_2O\) - not fully shown in this diagram); Energy source: Sunlight; Products: \(O_2\) (and glucose - partially inferred)
