If a plant appears blue to us, what wavelength of light is being reflected?
a) blue
b) green
c) red
d) yellow

The correct answer is: A) blue

Plants, as photosynthetic organisms have the ability to convert Sunlight energy into chemical energy. They do that thanks to light-absorbing molecules - pigments that absorb only specific wavelengths of visible light. The set of wavelengths that a pigment does not absorb are reflected, and that reflected light is what we see as color.

Because of that, plants appear green to us: pigments chlorophyll a and b  within plants reflect green light.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
