Phytochromes exist in two interconvertible forms PR because it absorbs red (R; 660 nm) light PFR because it absorbs far red (FR; 730 nm) light
These are the relationships:
Absorption of red light by PR converts it into PFR
Absorption of far red light by PFR converts it into PR.
In the dark, PFR spontaneously converts back to PR.
What else can I help you with?
In which form is the phytochrome at the end of a sunny day?
Primarily PR far red phytochrome(novanet)
What is the prefix that means plant?
phyto-. e.g. phytochrome
Are all wavelengths of light equal in phototropism?
No. Different forms of phytochrome absorb different wavelengths of light. Different forms of phytochrome are scattered throughout the plant. This allows the plant to perceive different intensities, wavelengths, and quality of light. Hope that helped!
Is switch an adjective?
No, switch can be a verb or a noun. Adjective forms could be switched or switchable.
What morphogenetic process are under the control of phytochrome?
permeability of membrane conductance leaf movement
Which phytochrome controlled responses displays far-red Reversibility?
Low fluorescence response
Why do plants grow better under red light?
The photosynthesis pathway has phytochrome systems which response to red light.
What is the photoreceptors that allow plants to detect day length?
Phytochrome is the photoreceptor that allows plants to detect day length.
What is the photoceptor that allows plants to detect day length called?
Phytochrome is the photoreceptor that allows plants to detect day length.
What is the photoreceptor that allows plants to detect day length is called?
Phytochrome is the photoreceptor that allows plants to detect day length.
What is the pigment responsible for photoperiodism?
Action spectra and photoreversibility experiments show that phytochrome is the pigment that receives the red light. Red light is the most effective color in interrupting the night-time portion of the photoperiod.
What are two forms of drama?
The two forms of drama are tragedy and comedy.
