select the correct statement(s) about photosynthesis.
photosynthesis occurs in the leaf of green plants.
the reactants of photosynthesis are oxygen and water.
photosynthesis has two different phases one that is light dependent and one that is light independent.
the products of photosynthesis are glucose and oxygen.
photolysis breaks the water molecule apart.
atp is only consumed in photosynthesis not produced.

Explanation:

• Photosynthesis occurs in the leaf of green plants: Leaves contain chloroplasts (site of photosynthesis). Chlorophyll in chloroplasts captures light.
• The reactants of photosynthesis are oxygen and water: Incorrect. Reactants are \(CO_2\) (carbon - dioxide) and \(H_2O\) (water).
• Photosynthesis has two different phases one that is light dependent and one that is light independent: Light - dependent reactions (occur in thylakoid) and light - independent reactions (Calvin cycle, occurs in stroma).
• The products of photosynthesis are glucose and oxygen: \(6CO_2+6H_2O

ightarrow C_6H_{12}O_6 + 6O_2\) (overall equation).

• Photolysis breaks the water molecule apart: In light - dependent reactions, \(2H_2O

ightarrow O_2 + 4H^{+}+4e^{-}\).

• ATP is only consumed in photosynthesis not produced: Incorrect. ATP is produced in light - dependent reactions (\(ADP + Pi

ightarrow ATP\)) and consumed in light - independent reactions.

Answer:

Photosynthesis occurs in the leaf of green plants, Photosynthesis has two different phases one that is light dependent and one that is light independent, The products of photosynthesis are glucose and oxygen, Photolysis breaks the water molecule apart.
