5. Which happens last in the process of photosynthesis? The plant captures the sun's energy
Oxygen exits the leaf.
Water is taken up by the plant's roots.
O Carbon dioxide enters the leaf.

Oxygen exits the leaf

Explanation:

Photosynthesis is the process whereby green plants and other certain organisms manufacture their own food using sunlight as an energy source. The photosynthetic process makes use of carbon dioxide and water to produce glucose (sugar) and oxygen.

Water and carbon dioxide must first be taken in by the plants from the soil and atmosphere respectively in order to perform the process. Glucose is produced as the main product while oxygen is produced last as a waste product of the process. Hence, the EXIT OF OXYGEN FROM THE LEAF is the last thing that occurs in photosynthesis.
