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.
Answered by GPT-4o mini
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.
Answered by GPT-4o mini
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.
Answered by GPT-4o mini
The original energy for photosynthesis to begin comes from **light**. Specifically, light energy is captured by chlorophyll in the chloroplasts of plant cells, initiating the process of photosynthesis.

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.
