6. Tropism

I choose to use a grape vine as an example of tropism. Tropism is the happening of an organism responding to an environmental catalyst affecting its growth patterns. These are those instances where you see vines climbing up and or covering walls, ladders, and even buildings.

Tropism is also broken into four different types:
-Photo Tropism: responds to where the most sunlight is making photosynthesis more productive.
-Thigma Tropism: responds to touch of objects.
-Gravity Tropism: responds to the effects of gravity.
-Hydera Tropism: responds to water; where it is.
