C. [tex]$CO _2+ H _2 O +$[/tex] Energy
D. [tex]$C _6 H _{12} O _6+ O _2$[/tex]
Answer (1)
Photosynthesis uses carbon dioxide, water, and energy to produce glucose and oxygen.
The reactants are C O 2 , H 2 O , and energy.
The options that represent the reactants are 6 C O 2 + 6 H 2 O + Energy and C O 2 + H 2 O + Energy.
Therefore, the reactants of photosynthesis are carbon dioxide, water, and energy.
Explanation
Understanding the Problem The question asks us to identify the reactants of photosynthesis from a list of chemical equations. Photosynthesis is the process where plants use light energy to convert carbon dioxide and water into glucose and oxygen.
Identifying Reactants and Products The general equation for photosynthesis is: 6 C O 2 + 6 H 2 O + Energy → C 6 H 12 O 6 + 6 O 2 This means that carbon dioxide ( C O 2 ), water ( H 2 O ), and energy (in the form of light) are the reactants, while glucose ( C 6 H 12 O 6 ) and oxygen ( O 2 ) are the products.
Comparing Options Now, let's compare the given options with the reactants we identified:
6 C O 2 + 6 H 2 O + Energy: This matches the reactants in the balanced equation for photosynthesis.
C 6 H 12 O 6 + 6 O 2 : This represents the products of photosynthesis.
C O 2 + H 2 O + Energy: This also represents the reactants of photosynthesis, but it is not the balanced equation.
C 6 H 12 O 6 + O 2 : This represents the products of photosynthesis.
Final Answer Therefore, the options that represent the reactants of photosynthesis are 6 C O 2 + 6 H 2 O + Energy and C O 2 + H 2 O + Energy.
Examples
Photosynthesis is crucial for life on Earth. Plants use it to convert carbon dioxide and water into glucose, which they use for energy, and oxygen, which we breathe. Understanding the reactants and products of photosynthesis helps us understand how plants sustain themselves and contribute to the environment. For example, knowing that carbon dioxide is a reactant highlights the importance of reducing carbon emissions to help plants thrive and maintain a healthy ecosystem.
