B. light reflects off of the t shirt and enters the human eye
The answer is 18 you multiply wavelength (6) times frequency (3)
24 molecules of H2O are needed by the plant to produce 4 molecules of sugar.
<h2>What is
photosynthesis?</h2>
The process by which plants convert carbon dioxide, water, and sunlight into oxygen and sugar-based energy is known as photosynthesis.
<h3>The photosynthesis equation is as follows:</h3>
6CO2 + 6H2O + Sunlight → C6H12O6 + 6O2
The following three significant activities are involved in photosynthesis:
1. Chlorophyll absorbs light energy.
2. Water molecules are divided into hydrogen and oxygen and light energy is converted to chemical energy.
3. Carbon dioxide is converted to sugars.
Therefore, a plant needs four molecules of H2O and four molecules of CO2 to make one molecule of glucose or sugar, hence a plant needs 24 molecules of H2O and 24 molecules of CO2 to make four molecules of sugar.
