Front

What pigment absorbs sunlight for photosynthesis?

Back

Chlorophyll is the pigment that absorbs sunlight for photosynthesis.

Front

At approximately which wavelength does chlorophyll a absorb most light?

Back

Chlorophyll a absorbs most light at approximately 425 nm.

Front

Which pigments absorb green and blue light but reflect orange and red light?

Back

Carotenoids are pigments that absorb green and blue light but reflect orange and red light.

Front

Chlorophyll absorbs a higher percentage of _____ and _______ light.

Back

Chlorophyll absorbs a higher percentage of red and blue light.

Front

The reactants of photosynthesis are...

Back

The reactants of photosynthesis are carbon dioxide and water.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll captures light energy, which is used to convert carbon dioxide and water into glucose and oxygen.

Front

What are the two main types of chlorophyll?

Back

The two main types of chlorophyll are chlorophyll a and chlorophyll b.

Front

What color of light does chlorophyll reflect?

Back

Chlorophyll primarily reflects green light.

Front

What is the significance of the thylakoid membrane in photosynthesis?

Back

The thylakoid membrane contains chlorophyll and is the site of the light-dependent reactions of photosynthesis.

Front

What is the difference between chlorophyll a and chlorophyll b?

Back

Chlorophyll a is the primary pigment in photosynthesis, while chlorophyll b assists by capturing additional light wavelengths.
