Volatile Secondary Metabolites in Plant Stress Responses In 2007, researchers Casey Delphia, Mark Mescher, and Consuelo De Moraes (pictured at left) published a study on the production of different volatile chemicals by tobacco plants in response to predation by two types of insects: western flower thrips and tobacco budworms.

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 flowering
