We found that green spring leaves are almost exclusively associated with yellow leaf colour at senescence in autumn. Species with red autumn leaves almost always have at least some red colouration in their spring leaves. However, about half of the species with red spring leaves have yellow autumn...
Why is seed dispersal important in the life of plants. What would be the consequences of having seeds that simply fell to the ground underneath the parent tree? How do trees make food for themselves in autumn when they have no leaves? ...
Explain how the lack of phototropism in an adult plant contributes to the initiation of leaf senescence? What is plant grafting? Describe this process in detail. Explain what would happen to a plant if it is not developing the root ...
Treatment depends on the cause; for disease-induced withering, appropriate treatments may help, but for natural senescence, there is no remedy.

Photosynthesis is the process by which plants use energy from the sun to convert carbon dioxide and water into glucose and oxygen. The glucose is then stored for use as fuel by the plant, and oxygen is released back into the atmosphere. B...
The reflectance, transmittance and absorption spectra of Acer platanoides leaves were recorded in the progress of full-term autumn senescence and compared with absorbance spectra of extracts from, and pigment contents in, these leaves. The observed changes in leaf spectra and development of intensive ...
(4) that they function according to the "defense indication hypothesis," which states that red leaves are chemically defended because anthocyanins correlate with various defensive compounds; or (5) that because sexual reproduction advances the onset of leaf senescence, the pigments might indicate to ...

Explain how the lack of phototropism in an adult plant contributes to the initiation of leaf senescence? Why does aging occur? Discuss two hypotheses on what causes the cells in our body to age. Include the scientific evidence suppor...
