The environment in which plants grow affects their structural adaptations and how they perform vital life processes.
Give the balanced chemical equation for photosynthesis.
The evergreen shrub Euonymus japonicus grows in both exposed coastal sand dunes and sheltered woodland understories.
Suggest why leaves from the coastal dune population have a thicker waxy cuticle than leaves from the woodland population.
Explain why leaves from the woodland population have a larger surface area per unit mass than those from the coastal dune population.
The rate of photosynthesis in commercial glasshouses is heavily influenced by environmental controls.
Explain the factors that limit the rate of photosynthesis of glasshouse crops on a bright but freezing cold morning in early spring.
Explain the factors that limit the rate of photosynthesis of glasshouse crops on a very hot, sunny, and completely unventilated afternoon in mid-summer.
Describe how you could investigate and compare the rate of photosynthesis in an aquatic plant (such as Elodea) at two different light intensities.
