Are there occasions in a plants life when it is unable to photosynthesize?

Homework Answers

Answer #1

Solution

  • as leaves start to lose their green colors in fall at autumn senescence they can no longer do photosynthesis.
  • When leaves are irradiated by excess light energy, the chloroplasts that carry out photosynthesis can easily suffer oxidative stress and stop photosynthesizing.
  • the photosynthesis shuts down at noon, or at the peak of the hottest hours of the day, because too much energy from the sun can damage biological structure.
  • In flood high water stress, due to closure of stomata and halted water absorption stops ohotosynthesis.

Some plants with genetic defects to Rubisco are unable to photorespire properly due to an inability to bind to excess oxygen that tends to build up when stomata close. These plants have been observed to have cellular damage under these conditions. Researches identify this as evidence that photorespiration is a protective mechanism in plants and not a wasteful process. Why might a disabling of the photorespiratory pathway lead to cell damage and how might the process of photorespiration reduce this...

Suppose you harvest and weigh all your 10000 blue-eyed grass plants that grew in one year, and estimated their biomass to be approximately 80 g(carbon)/m2/yr. Assuming respirational needs to be about 20% of total photosynthesis, how much total carbon did these plants photosynthesize during the year of your study? None of these answers are correct 50 g(carbon)/m2/yr 20 g(carbon)/m2/yr 80 g(carbon)/m2/yr 100 g(carbon)/m2/yr

When Mendel crossed pea plants that were true breeding for purple flowers (PP) with pea plants with white flowers (pp), all of the offspring had purple flowers.  When he let these offspring self-fertilize, he got purple and white second generation (F2) offspring in a phenotypic ratio of 3:1. But, we know that the genotypic ratio is really 1:2:1.  Why? (1 point)
