What factor primarily determines the time of year that a plant flowers?
Photoperiod determines the time of flowering in many plants. Accordingly the plants have been classified as short day plants, long day plants and day neutral plants. A short day plant can be brought into flowering by putting in the dark for a specific period of time for the required days. Similarly, long day plants can be subjected to artificial light of desired intensity to initiate flowering.Photoperiod determines the time of flowering in many plants.

What is the difference between short day and long day plants in terms of their growth and flowering patterns?
Short day plants require a longer period of darkness to flower, while long day plants need more hours of daylight to bloom. This difference in light exposure affects their growth and flowering patterns.
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
What is photoperiod?
Photoperiodism is a response that certain plants have to decreases or increases in the amount they receive in a day (which is normally produced by seasonal movement of the sun - longer and shorter days). Some plants require short days to initiate flower formation, while others long day length initiates flowering. This process can be artificially created in greenhouses using curtains and artificial light to "trick" certain plants like chrysanthemums and poinsettia to flower outside of their natural flowering period. Photoperiodism is controlled at a cellular level by photoreceptor proteins in the cells of the plants. Phototropism is a the mechanism whereby plants grow towards the light (like a houseplant growing towards the window), or in the case of certain flowers like sunflower the way in which the "flower" tracks the path of the sun
What is the difference between long day and short day plants and how do their growth patterns vary based on the length of daylight they receive?
Long day plants require a certain minimum amount of daylight to flower, while short day plants need a specific maximum amount of daylight. Long day plants flower when days are longer than a critical length, while short day plants flower when days are shorter than a critical length. The growth patterns of these plants vary based on the length of daylight they receive, with long day plants flowering in the summer when days are longer, and short day plants flowering in the fall when days are shorter.
Are ferns a flowering plant?
A fern is not a flowering plant.All kinds of ferns existed long before flowering plants developed.
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.
What environmental factor controls flowering In plants?
The primary environmental factor that controls flowering in plants is photoperiod, which refers to the length of daylight hours. Many plants are sensitive to the duration of light and darkness they experience, leading to either short-day or long-day flowering responses. Additionally, temperature, particularly in the form of vernalization (a period of chilling), can also influence flowering timing. Other factors, such as water availability and nutrient levels, can indirectly affect flowering by influencing plant health and growth.

Why short day and long day are not the best descriptive terms for these types of flowering plants?
The terms "short day" and "long day" can be misleading because they imply that the plants rely solely on the duration of light exposure to trigger flowering. In reality, these plants respond to the relative length of darkness rather than light, as they are sensitive to the photoperiod's nighttime duration. Additionally, environmental factors such as temperature and light quality can also influence flowering, making these terms overly simplistic. A more accurate description would focus on the plants' responses to the length of darkness they experience.
What plant is also known as flowering plant?
Angiosperms are also known as flowering plants because they produce flowers as part of their reproductive structures. These plants bear seeds enclosed within an ovary or fruit. They are the most diverse group of plants on Earth, with over 300,000 known species.
What is the difference between short day and long day plants in terms of their growth and flowering patterns?
Short day plants require a longer period of darkness to flower, while long day plants need more hours of daylight to bloom. This difference in light exposure affects their growth and flowering patterns.
Is inhibiting of flowering in short day plants a phytochrome response?
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 should you know about day-neutral plants?
Daily periodicity of light (photoperiod) plays very important role in initiating flowering in a variety of plants. On this basis plants are classified as 1. long day plants, 2. short day plants and 3. day -neutral plants. Day neutral plants are not affected by daily photoperiod for their flowering whereas 1 & 2 category require long duration & short duration of light for flower initiation respectively.
What is Chailakhyans hyphothesis of vernalization?
according to this hypothesis,the application of gibberellins on long day plants in non-inductive cyles will induce flowering,while in short day plants if non inductive cycle is provided then application of gibberellin has no effect on floweringi.e. flowering will not be induced.
What are plants requiring long nights to flower called?
Plants requiring long nights to flower are called short-day plants. These plants use the length of darkness as a cue to initiate flowering. Examples include poinsettias, chrysanthemums, and strawberries.
