1 pts
plant cells and many microorganisms use _ energy to combine molecules of carbon dioxide and water into complex, energy-rich organic compounds and release _ into the environment.

thermal, carbon dioxide
hydraulic, oxygen
solar, oxygen
solar, carbon dioxide

question 6
1 pts
plants use chlorophyll to capture light energy for use in creating glucose (c6h12o6). this process is called ___.

phototrophism
photoperiodism
photosynthesis

Explanation:

Analyze Question 5

The sentence describes the process of combining carbon dioxide and water into complex, energy-rich organic compounds (like glucose). This biochemical pathway is Photosynthesis.

• The primary energy source driving this reaction in plant cells and photosynthetic microorganisms is light energy from the sun, which is solar energy.
• The chemical equation for this process is:

$$6\text{CO}_2 + 6\text{H}_2\text{O} + \text{light energy} ightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2$$

• This shows that oxygen (\(\text{O}_2\)) is released into the environment as a byproduct.
• Therefore, the blanks should be filled with "solar" and "oxygen".

Analyze Question 6

The prompt describes plants using the pigment chlorophyll to capture light energy to synthesize glucose (\(\text{C}_6\text{H}_{12}\text{O}_6\)).

• This biological process of converting light energy into chemical energy is defined as Photosynthesis.
• Phototrophism (usually phototropism) refers to growth in response to light.
• Photoperiodism refers to physiological reactions to the length of day or night.
• Therefore, the correct term is photosynthesis.
