- Light is often the most important environmental factor for inducing a plant to flower, but it is not the intensity of light. What it the important aspect?arrow_forwardA 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.arrow_forwardWe know that short-day plants do not really need short days, but actually long nights. Describe the type of treatment that proves this. Is some kind of light given during the night or some period of darkness given during the day?arrow_forward
- Submerged plants receive lesser illumination as compared to exposed floating plants in a lake. Give reasons.arrow_forwardWhich (look at figure) is an accessory pigment in red flowers?arrow_forwardThis plant is referred to as This plant is referred to as : Venus flytrap : butterwort : sundew : bladderwortarrow_forward
- Why do plants appear green? They reflect green light. They pass green light to accessory pigments. They mix blue and red light. They absorb green light.arrow_forwardPhytochrome is a plant pigment protein that mediates plant infection promotes plant growth mediates morphological changes in response to red and far-red light inhibits plant growtharrow_forwardWould a plant be able to grow to maturity and produce seeds if kept in total darkness? Why?arrow_forward

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_forward
