This is because growth, chlorophyll production, flowering and fruiting only occur if the plant is exposed to a band of light with 640-720 nm. Plants receive this band of light naturally through the sun, but when solar energy is not available it is possible to use cultivation lamps that emit this type of light band, which corresponds to the yellow/red spectra.

What is crossing over and why is it important?
DiKsa [7]
<span>Crossing over or Chromosomal crossover is the process that occurs in cells between the stages of phrophase  I and metaphase I in meiosis. It is important because it is responsible in the exchange of genetic material between homologous chromosomes during sexual reproduction. This process ensures the normal segregation of chromosomes during meiosis, and genetic variation. Homologous chromosomes pair up with each other and exchanges segments of their genetic material to form new chromosomes. Thomas Hunt Morgan described crossing over in his theory of genetics. </span>
