If a plant flowers in a controlled chamber with a daily cycle of 10 hours of light and 14 hours of darkness, is it a short-day plant? Explain.
Predict whether flowering in a short day plant with a minimum critical length of 14 hours would be expected to occur in the following situations.
The plant is exposed to 15 hours of daylight and 9 hours of darkness uninterrupted.
The plant is exposed to 9 hours of daylight and 15 hours of darkness.
The plant is exposed to 9 hours of daylight and 15 hours of darkness, with 10 minutes exposure to red light in the middle of the night.
A short-day plant flowers only when exposed to light for less than 12 hours
long. Which of the following would cause the plant to flower? *
O a 13-hour night and 11-hour day with 1 minute of darkness after 6 hours
a 12-hour day and 12-hour night with a flash of red light
an 8-hour day and 16-hour night with a flash of white light after 8 hours
O a 9-hour night and 15-hour day with 1 minute of darkness after 7 hours
24 hours of continuous light

- Please help this is hw and I want to know why I'm wrong Why do many plants use pathways that detect light to regulate their flowering? Selected Answer: This allows plants to link flowering to temperature, which corresponds to the season when conditions are optimal Answers: This allows plants to link flowering to day length, which corresponds to the season when conditions are optimal Flower petals carry out high levels of photosynthesis and require high light conditions This allows plants to link flowering to temperature, which corresponds to the season when conditions are optimal A minimum amount of light is always necessary for floweringarrow_forwardWhat If?

Drain off excess alcohol from the buds and aseptically excise the anthers from each bud. Remove the filaments and culture the anther on one of the agar media provided. Label the stage of development of the bud on each petri dish as the anthers are cultured. Seal the Petri dishes with parafilm. Incubate in the dark at 26 to 28ºC for 4 to 8 weeks or until small plants can be seen growing out of the anthers. Then transfer to diffuse light. Record the results of the experiment in table form and submit the report. Observation: The culture was contaminated after 8 weeks of incubation…arrow_forward
