Nataly_w [17]
The correct effects of Volatiles are; Volatiles may warn nearby plants of the same species, so that they can mount a biochemical defense. They may also attract parasitoid wasps to attack an insect herbivore.

geniusboy [140]

Answer:

Passes absorbed energy to chlorophyll A.

Explanation:

Chlorophyll is a pigment found on the chloroplasts, it absorbs and reflects light's fotons in order to fuel the photosynthesis process where plants convert light into energy. There are two types of chlorophill:

  • <em>Chlorophyll A:</em> a blue/green substance that is always necessary for photosyntesys, it absorbs light from red to blue areas and it acts as a primary electron donor in the electron transport chain.
  • <em>Chlorophyll B: </em>a yellow/green substance that absorbs only blue light, it serves as an extension for the plant to absorb a broader range of light. <em>The extra energy absorbed by this clorophyll is then tranfered to chlorophyll A</em>.

I hope you find this information useful and interesting! Good luck!
