Answer:

mediates morphological changes in response to red and far-red light

Explanation:

Phytochrome is a blue-green protein pigment that participates in plant physiology in response to periodic light phenomena, responsible for numerous developmental processes. This substance, in two possible forms: phytochrome R (inactive) and F (active), is dissolved in the hyaloplasma of plant cells, capturing specific wavelengths from sunlight.

Depending on the time of day, ie the daily light, these two types of phytochrome can convert to each other, according to the wavelength absorption that comprises the frequency of the red color (long or short).

Thus, during the day, plants capture the red wavelength (660nm), transforming the phytochrome R and F, as well as the  far-red wavelength (760nm), to a smaller extent, inverting the phytochrome F to R.

As the variation in daily light decreases (late afternoon), plants begin to capture the  far-red wavelength more intensely, concentrating more phytochrome R than F. This inactivation action remains in the dark (during night). Therefore, the perception of this oscillation induces the vegetables to organic behaviors combined with the photoperiod.
