Verified step by step guidance

Understand the process of photosynthesis: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. The general equation for photosynthesis is:

{6 CO 2}_{+ {6 H 2 O}_{\to {C 6 H 12 O 6}_{+ 6 O 2}}}

Identify the reactants in photosynthesis: The reactants in the photosynthesis equation are carbon dioxide (

CO 2

) and water (

H 2 O

). These are essential for the production of glucose.

Recognize the role of carbon dioxide: Carbon dioxide is a critical component in the photosynthesis process. It provides the carbon atoms needed to form glucose, a monosaccharide. Without carbon dioxide, the plant cannot synthesize glucose.

Consider the other elements: Nitrogen, phosphorus, and sulfur are important for various plant functions, such as protein synthesis and energy transfer, but they are not directly involved in the formation of glucose during photosynthesis.

Conclude the essential element: Based on the photosynthesis equation and the role of carbon dioxide in providing carbon for glucose, carbon dioxide is essential for a plant to produce monosaccharides like glucose during photosynthesis.
