- A long-day plant will flower if Select one: O the duration of continuous light is less than a critical length. O the duration of continuous light exceeds a critical length. O the duration of continuous darkness is less than a critical length O it is kept in continuous far-red light. O the duration of continuous darkness exceeds a critical length.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 lightThe oat coleoptiles of the seedlings (in the picture) have been modified: either cut or placed in a light-blocking tube. Explain which ones will stills bend toward a directional light source??

Characteristics sunny shaded Leaf color Lime Green Pale Green Direction of Growth Grows upward towards the direction of sunlight Oriented in the direction of the light but growth is bent downwardPlease 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 flowering

Which light intensity and water temperature caused the plant to produce the most amount oxygen gas during the process of photosynthesis? Why Which light intensity and water temperature caused the plant to produce the least amount oxygen gas during the process of photosynthesis? Why?1) Does the three t-tests support the hypothesis: of manipulating light exposure will influence the flowering time of Brassica rapa plants by using light from the sun and using incandescent bulbs, or not? If it did not support the hypothesis, then what changes would you make? 2) Do these three t-tests have different growth rates? 3) Is there anything to learn about this study of the graphs and t-tests?
