Nancy is explaining why chlorophyll is classified as a plant pigment and how it is useful in photosynthesis. Which property of chlorophyll would be most appropriate for her to cite? A. chlorophyll's ability to absorb light
B. chlorophyll's green color
C. chlorophyll's presence in chloroplasts
D. chlorophyll's reactivity with oxygen

A. chlorophyll's ability to absorb light

Explanation:

Within the chloroplasts of plants, a complex biochemical mechanism, photosynthesis, takes place. Here, light energy is converted into chemical energy in the form of stable carbohydrates.

6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2

Carbon Dioxide + Water + Light       Glucose + Oxygen

In the chloroplast, the light-dependent and light-independent reactions in which sugars are  formed occur. In the light reaction that stimulates photosystems, pigments such as chlorophyll absorb light energy at specific wavelengths.

Specifically,  chlorophyll then forms photosystem complexes (PS I & PSII) with proteins- these absorb and transfer light electrons etc to other downstream reactions like photolysis and the electron transport chain.

1)

i))the process of preparing food by green plants in the presence of sunlight is called photosynthesis.

ii) leaf is the site for photosynthesis.

iii) it takes place as,

6h2o+6co2=c6h12o6+602
