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 else can I help you with?
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 does sunlight affect plant reproduction?
It is well known that photoperiodism is largely responsible for flowering. The initiation of reproductive phase is a light dependent phenomenon in majority of plants.
What induces the flowering in plants such as tobacco and cocklebur and the germination of certain lettuce seeds?
this is for an a.p. bio quiz. the answere is A. on the test version a. for any differnt test versions the aswere is photoperiodism. Darkness induces flowering. with out light (photo) it begins to flower. all other answeres are compleatly wrong except possibly lunar phases in some situations with differnt plants
What do you understand by photoperiodism and what is its significance?
Photoperiodism is a plant's response to the length of day and night, which triggers changes in growth, development, and flowering. It is significant because it helps plants synchronize their life cycles with the changing seasons, allowing them to flower and reproduce at the most advantageous times. This adaptation enables plants to effectively utilize environmental cues to optimize their survival and reproductive success.
How do you know which type of plants are flowering plants?
Angiosperms are flowering plants
The response of flowering plants to the daily daylight darkness conditions?
Flowering plants respond to daily cycles of light and darkness through a process called photoperiodism. This involves sensing the duration of light and dark periods, which triggers physiological changes related to flowering. For example, short-day plants flower when exposed to longer periods of darkness, while long-day plants flower when exposed to shorter periods of darkness. This response allows plants to synchronize their reproductive efforts with seasonal changes in day length.

It is well known that photoperiodism is largely responsible for flowering. The initiation of reproductive phase is a light dependent phenomenon in majority of plants.
Commercial plant growers artificially control the lengths of days and nights This produces a response called?
"photoperiodism." Plants detect the duration of light and dark periods to regulate their growth, flowering, and other physiological processes. By manipulating light exposure, growers can induce specific developmental stages in plants.

What did the early experiments on photoperiodism demonstrate?
Early experiments on photoperiodism demonstrated that the length of daylight exposure influenced the flowering and reproductive processes of plants. This research showed that plants could sense and respond to changes in day length, triggering physiological changes such as blooming. These findings laid the foundation for understanding the role of light in regulating plant growth and development.
What is the response of plants to periods of light and dark?
photoperiodism

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
Plant sellers can cause plants to bloom on schedule by influencing the length of the?
daylight hours - its called photoperiodism
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 response of plants to periods of light and dark called?
It is called photoperiodism
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.
