What are the effects of the tropisms caused by light and gravity?
A tropism is a growth response whose direction is determined by the direction of the stimulus. Growth towards the stimulus is called a positive tropism. Growth away from the stimulus is called a negative tropism. The response to light is called phototropism. Shoots are positively phototropic, roots are negatively phototropic. The response to gravity is called gravitropism (or sometimes geotropism). Shoots are negatively gravitropic and roots are positively gravitropic. http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/T/Tropisms.html
How is a plant shoot positively photo tropic?
Phototropic is a word to describe if the plant moves towards light sources or away from light sources. Positively phototropic means it moves towards light. Most, perhaps all, plants will grow towards a light source. Plants need light energy so they have evolved to grow in the direction of the best light. Negatively phototropic means it moves away from light. Vampires are known to be negatively phototropic.

What is the physical basis of the phototropic response in plants?
Tropisms are growthg responses in plants in which the direction of growth depends on the direction of the stimulus. Phototropism is the response to light. The shoots of plants are positively phototropic (grow towards the light) while the roots are negatively phototropic (grow away from light).Experiments carried out in 1880 by Charles Darwin and his son Francis showed that the stimulus was detected by the tip of the shoot but the bending response took place just below the tip.In 1913 the Dutch plant physiologist Boysen-Jensen showed that a chemical substance produced in the tip of the shoot passed to the bending region to cause the response and that this substance passed down the shaded side of the shoot.F. W.Went extracted the growth substance which was identified as auxin. He showed that the phototropic response was due to the unequal distribution of auxin in the shoot. More auxin accumulates on the shaded side of the shoot and causes more rapid cell elongation on that side, so that the shoot bent over towards the light.See related links below
What is climbing roots?
Any of the short adventitious roots that develop from the stems of certain climbing plants, e.g. ivy (Hedera helix), and serve to attach the plant to its support. Climbing roots are negatively phototropic and thus grow into darkened tissues in bark or crevices in walls. Their function is enhanced by the secretion of mucilaginous substances from the root tip.
