Yes, the inhibition of flowering in short day plants is indeed a phytochrome response. These plants require a specific light duration, typically shorter days, to initiate flowering. Phytochromes, which are light-sensitive proteins, play a crucial role in detecting the light conditions and triggering the flowering process by regulating gene expression in response to the length of day and night. When light exposure is insufficient (long days), phytochrome activation prevents flowering.

What are the differences between responses of mammals and flowering plants?
Mammals typically respond to their environment through behavior and physiological changes, such as seeking shelter or regulating body temperature. Flowering plants, on the other hand, respond through growth patterns, altering leaf orientation, or flowering in response to light or temperature changes. Both organisms have evolved different mechanisms to adapt and survive in their respective environments.
What is the protoreceptor that allows plants to detect day length called?
The protoreceptor that allows plants to detect day length is called phytochrome. Phytochromes are photoreceptors that absorb light, particularly in the red and far-red spectrum, and play a crucial role in regulating various aspects of plant growth and development, including flowering time in response to changes in day length. They help plants determine the length of day and night, influencing their physiological responses to seasonal changes.
What does the length of night or dark periods control in flowering plants?
The length of night or dark periods controls the process of photoperiodism in flowering plants, which determines their flowering time. Plants can be classified as short-day, long-day, or day-neutral based on their flowering response to varying lengths of light and darkness. In short-day plants, flowering is triggered when nights are longer, while long-day plants require longer daylight periods to initiate flowering. This mechanism allows plants to synchronize their reproductive cycles with seasonal changes for optimal growth and seed production.
How do you know which type of plants are flowering plants?
Angiosperms are flowering plants
What is unigue about flowering plants?
Flowering plants produce seeds.
What is the difference between florigen and phytochrome?
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
Why do plants grow better under red light?
The photosynthesis pathway has phytochrome systems which response to red light.
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.
What is the photorecepter that allow plants to detect day lenght called?
The photoreceptor that allows plants to detect day length is called phytochrome. Phytochrome is a protein that can exist in two forms, which can sense red and far-red light, enabling plants to gauge the duration of light exposure. This mechanism helps regulate various developmental processes, including flowering and seed germination, based on the length of day and night.
What are the differences between responses of mammals and flowering plants?
Mammals typically respond to their environment through behavior and physiological changes, such as seeking shelter or regulating body temperature. Flowering plants, on the other hand, respond through growth patterns, altering leaf orientation, or flowering in response to light or temperature changes. Both organisms have evolved different mechanisms to adapt and survive in their respective environments.
Are plants flowering or none flowering?
You get both flowering plants and non-flowering plants; non-flowering are things like mosses, ferns and liverworts which produce spore, flowering plants produce seeds

What is the photoreceptors that allow plants to detect day length?
Phytochrome is the photoreceptor that allows plants to detect day length.
What type of plants are flowering?
There are two types of flowering plants. These two types of flowering plants are the perennials and the annual flowering plants.
Which factors control flowering in short day plants?
Short day plants flower when the duration of darkness exceeds a critical period, typically requiring longer nights. Key factors that control this process include light duration, the presence of phytochrome proteins that detect light, and the plant's internal circadian rhythms. Additionally, environmental conditions such as temperature and stress may influence flowering. Ultimately, these factors trigger hormonal changes that promote flowering.
What way does pollination differ between non-flowering seed plants and flowering plants?
Flowering plants require pollinatio non-flowering plants do not.
What are the classification of plants?
flowering plants and non-flowering plants
