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.
Explain 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 refer to the plant's response to the length of darkness rather than the actual hours of daylight. Short-day plants require longer nights to initiate flowering, while long-day plants need shorter nights, regardless of the total daylight hours. Additionally, some plants can exhibit flowering responses based on specific light duration thresholds rather than simply classifying them by day length, making these terms overly simplistic. Ultimately, the flowering response is more accurately tied to the photoperiod, or the ratio of light to dark periods.
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.
Which descides the F2 generation in Mendel's experiment?
three times as many tall plants as short plants
What was the ratio of tall to short plants in the F generation of Mendel's experiments?
In Mendel's experiments with pea plants, the ratio of tall to short plants in the F1 generation was 100% tall, as tall (dominant) traits masked the short (recessive) traits. However, in the F2 generation, after self-pollinating the F1 plants, the ratio of tall to short plants was approximately 3:1, with three tall plants for every one short plant.
Do short day plants need a really long night?

Where do short day plants live?
In general, short-day (i.e. long-night) plants flower as days grow shorter (and nights ... Day-neutral plants, such as cucumbers, roses and tomatoes, do not initiate ...
Is the following statement true or false only pea plants that have two recessive alleles for short stems will be short?
False. Pea plants can have short stems if they have two recessive alleles for short stems, but they can also have short stems if they have a combination of dominant and recessive alleles that result in a short stature.
Short-day plants really need a long night?
true
What is plants that flower when nights are short?
Poinsettias and chrysanthemums are short day plants. They need a certain number of hours of uninterrupted darkness to cause the plant to start flowering. Poinsettias need 18 hours of darkness to trigger this. Chrysanthemums need twelve hours of darkness.
