It will take a certain amount of time to respond to certain types of light, and a phytochrome only responds to red and far red. Otherwise, it will repel all other types of light

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.
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!
Does an annual plant bear fruit or flowers every year?
no! it depends on the weather and on the soil the flower is planted and on how you took good care of your plant....
How does critical night length control photoperiodism?
Photoperiodism is the response of the plant to daylight and darkness. For short day plants it will bloom in darkness and when darkness exceeds critical night length, for long day plants it will bloom during daylight and when darkness is less than the critical night length.
A plant sits on a window sill over time the stems of the plant curve toward the light coming in the windowThis process is called A phototropism B photoperiodism C gravitropism D phytochromism?
Phototropism
What is the prefix that means plant?
phyto-. e.g. phytochrome
Plant sellers can cause plants to bloom on schedule by influencing the length of the?
daylight hours - its called photoperiodism
What is the pigment responsible for photoperiodism?

What are the 3 plant tropisms and their functions?
The three plant tropisms include geotropism, thigmotropism,hydrotropism and photoperiodism.
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!

photoperiodism.
In which form is the phytochrome at the end of a sunny day?
Primarily PR far red phytochrome(novanet)

What has the author R M M Crawford written?
R. M. M. Crawford has written: 'Studies in plant survival' -- subject(s): Plants, Adaptation, Plant ecology 'Morphological and metabolic changes in the apical bud with relation to photoperiodism in Salvia splendens' -- subject(s): Buds, Salvia, Photoperiodism
What factor controls photoperiodism in flowering plants?
Photoperiodism is a mechanism that plants and animals have that reacts to the length of the night and day. It influences flowering because certain types of flowers will only bloom after long periods of darkness, while others can flower during shorter night time periods. Photoperiodism allows the plant to know what time it should flower.
How does critical night length control photoperiodism?
Photoperiodism is the response of the plant to daylight and darkness. For short day plants it will bloom in darkness and when darkness exceeds critical night length, for long day plants it will bloom during daylight and when darkness is less than the critical night length.
What are the example of chromoprotein?
The red and far red light plant signalling molecules Phytochrome are Chromoproteins.http://www.nature.com/nrm/journal/v3/n2/abs/nrm728.html
