Question

in what type of plant cells does most photosynthesis occur?
tree bark cells
leaf cells
root cells
what wavelengths of light does chlorophyll best absorb? (check all that apply)
reds
yellows
blues
purples
greens

Explanation:

• For the first question: Leaf cells contain chloroplasts which are the sites of photosynthesis. Tree bark cells are mainly for protection and root cells are for absorption of water and minerals, not for photosynthesis.
• For the second question: Chlorophyll best absorbs red and blue wavelengths of light. It reflects green light (which is why plants look green), and does not have a high absorption for yellow and purple in the context of its main absorption spectra.

Answer:

• First question: leaf cells
• Second question: reds, blues
