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 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.
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
Are ferns a flowering plant?
A fern is not a flowering plant.All kinds of ferns existed long before flowering plants developed.

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.
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.
Why are my radishes flowering?
Radishes may flower due to stress factors such as high temperatures, lack of water, or old age. Flowering can also occur if the radishes are left in the ground for too long.
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.

What is the difference between a hartstongue and a dafodil?
A hartstongue is a type of fern that has long, strap-like fronds, while a daffodil is a type of flowering plant from the Narcissus genus that produces yellow or white trumpet-shaped flowers. Hartstongues are non-flowering plants, while daffodils are flowering plants.
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.
What is the action of phytochrom pigment in plant flowering?
Phytochrom-FarRed increases during the day to inhibit flowering. At night it degrades slowly to Phytochrom-Red which does not inhibit flowering. "Short-Day" plants need long nights to complete this process in order to flower in the late summer.
