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 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
When Mendel crossed short tt pea plants with short pea plants the offspring were?
When Mendel crossed short tt pea plants (homozygous recessive) with short pea plants that were heterozygous for height (Tt), the offspring would display a phenotypic ratio of 1 short (tt) to 1 tall (Tt). This is because the short plants (tt) can only contribute recessive alleles, while the heterozygous plants (Tt) can contribute either a dominant (T) or a recessive (t) allele. Therefore, half of the offspring would be tall and half would be short.

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.
