Question

Horticulturists know that, for many plants, dark green leaves are associated with low light levels and pale green with high levels. (a) Use the photon theory to explain this behavior.

Answer 1

• In the reduction process of photosynthesis, electrons are transported from water to carbon dioxide.

• According to photon theory here the photons behave as light energy particle.
• By capturing sun energy (photons), chlorophyll aids in this process.An electron in the chlorophyll molecule gets excited from a lower to a higher energy state when chlorophyll receives energy from sunlight.

• Excessive sunshine is the main cause of leaves turning a darker green color. Lack of sunlight causes a plant's leaves to create more chlorophyll, which is what gives the plant its green hue.

• The color of the leaf is darker green than typical because of the increase in chlorophyll concentration per unit area.

What is photon theory?

The photon theory of light states that photons have simultaneous particle and wave behavior. pass through empty space at a constant speed, or "the speed of light". possess rest energy and zero mass.
