Photosynthesis is used to produce food for plants in the form of glucose. in the process, oxygen is released. as shown in the diagram, plants require water and carbon dioxide (from the air). what else is required for photosynthesis and what role does it play? a) light is required to provide energy for photosynthesis. b) atp is required as an energy source for photosynthesis. c) glucose is required as an energy source for photosynthesis d) oxygen is required to split water molecules in photosynthesis.

light is required to provide energy for photosynthesis

Explanation:

For photosynthesis to take place, it requires the presence of light and chlorophyll. The process has two stages; light and dark stage.

In the light stage, chlorophyll molecules absorb light energy which is used to split water molecules into oxygen and hydrogen atoms. The process is called photolysis.

water→ hydrogen atoms + oxygen.

The hydrogen atoms produced enter the dark stage while oxygen is released in the atmosphere. In the dark stage, carbon dioxide combines with the hydrogen atoms to form simple sugar such as glucose.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
