The object that absorbs green light is chlorophyll. Chlorophyll is a pigment found in plants that absorbs light primarily in the blue and red wavelengths while reflecting green light, which is why plants appear green.

The original source of energy in the food you eat is the sun. Through the process of photosynthesis, plants convert sunlight into chemical energy, which is then transferred through the food chain.

Chlorophyll reflects green light in the fall.
Leaves turn red in the fall because chlorophyll breaks down because there's less sunlight. As chlorophyll degrades, other pigments in the leaves, such as anthocyanins, become more visible, giving the leaves their red coloration.

The true statement is: The Calvin cycle is the light-independent (does not need light) step of photosynthesis and happens in the stroma.
The Calvin cycle occurs in the stroma of the chloroplasts and does not directly require light to function, although it relies on the ATP and NADPH produced during the light-dependent reactions.

The equation that best models cellular respiration is:
A: \( C_6H_{12}O_6 + 6O_2 \rightarrow 6H_2O + 6CO_2 + \text{Energy} \)
This equation indicates that glucose (\( C_6H_{12}O_6 \)) and oxygen (\( O_2 \)) are converted into water (\( H_2O \)), carbon dioxide (\( CO_2 \)), and energy during cellular respiration.
