a. Chlorophyll is the main plant pigment molecule in plants.
b. Chlorophyll absorbs light energy from the sun.
c. Carotenoids are mainly responsible for the fall color in leaves that we see.
d. There are two types of chlorophyll, a and b.
e. All of the above are true.
Identify which of the following statements is a lie?
Select one:
a. Even if plants have red leaves, they still perform photosynthesis.
b. Photosynthesis is vital in plants to produce food and energy they need for growth and cellular respiration. Therefore, all plants need the same amount of sunlight to make enough food to grow.
c. Aside from chlorophyll α and chlorophyll b in plants, plants also have carotenoids, which help plants absorb light energy for use in photosynthesis.

In addition, many plants contain other types of chlorophylls and accessory pigments. Suppose a new agricultural technology is developed in which accessory pigments are somehow embedded or injected into crops that naturally have only chlorophyll a. Explain the food production advantage that these plants could hypothetically provide if they could utilize many of these pigments rather than just one type of chlorophyllarrow_forward
- Diagram 3: Light Wave Absorption of Chlorophyll a and b. Chlorophyll a Chlorophyll b 400 450 500 550 600 650 700 Wavelength (nm) Plant chlorophyll chemicals will absorb, or take in, light wave energy in order to produce their own organic molecules used for cellular energy. Reflected light refers to those wavelengths of light that will "bounce off" of the chlorophyll and not be absorbed. Select the conclusion that most accurately summarizes the data in diagram 3. Red and blue light waves have equal importance during photosynthesis. The majority of light energy is attained from red light, while the blue light waves provide additional light energy to photosynthesis.
