florigen
)its a hormone responsible for inducing flowering in plants directly
)moves from leaves to the apex inducing flowering by phloem mechanism
)no inter conversion from one phase to other
phytochrome
)it is a light absorbing pigment which induces flowering in long day plants
)pigments p660 and p730 absorb red and far red light respectively
)p660absorbs red light and immediately converts into p730 and as p730 absorbs far red light which induces flowering thus flowering is induced in long day plants because p730 is present in day
Florigen is a plant hormone responsible for controlling the flowering process in response to environmental cues, while phytochrome is a photoreceptor protein that helps plants detect light quality and quantity for regulating various growth and developmental processes. Florigen specifically influences flowering, while phytochrome has a broader role in light signaling in plants.

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 is the difference between succeeding terms called?
The difference between succeeding terms in a sequence is called the common difference in an arithmetic sequence, and the common ratio in a geometric sequence.
What are phytochrome?
Phytochromes are photoreceptors found in plants that are sensitive to red and far-red light. They play a crucial role in regulating various plant responses, such as seed germination, stem elongation, and flowering, by switching between an inactive form (Pr) and active form (Pfr) in response to different light conditions. These light-induced structural changes help plants to detect and respond to changes in their light environment.
Are all wavelengths of light equal in phototropism?
No, not all wavelengths of light are equal in phototropism. Plants are most sensitive to blue and red light for their growth and development, as these wavelengths are absorbed by specific photoreceptors in the plant cells. Green light, on the other hand, is less effective in stimulating phototropic responses.
How does phytochrome act in plant photoperiodism?
Phytochromes are light-sensitive proteins in plants that regulate key processes in response to light, such as flowering in photoperiodism. Red and far-red light signals are perceived by phytochromes, which then initiate signaling pathways leading to changes in gene expression to control the plant's response to day length. This helps plants synchronize their growth and development with the changing seasons.
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
Which phytochrome controlled responses displays far-red Reversibility?
Low fluorescence response
What morphogenetic process are under the control of phytochrome?
permeability of membrane conductance leaf movement
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.
