What hormone cause photoTropism?
auxins
What are 4 examples of tropism?
geotropism (also known as gravitropism), phototropism, and hydrotropism.
What controls geotropism and phototropism?
When the auxins in the plant act towards gravity... positive geotropism is wen the plant goes to the direction of gravity which would be downwards..negative geotropism would be upwards going against the natural gravity Phototropism is when the plant reacts towards the photosynthesis conditions where when light acts on the plant so the auxins burst and the plant bends towards light..this is positive phototropism...but when the plant goes against the direction of light it is then negative phototropism
How do auxins cause a plant to grow toward a light source?
Auxins help plants grow towards sunlight by I KNOW BUT IM NOT TELLING YOU BRAINLESS PEOPLE WHO DECIDE TO LET THE COMPUTER TO WORK FOR THEM!
What is it called when a plant grows toward light?
It is called "phototropism". It is caused by the destruction (by light) of chemicals (called Auxins), produced by the growing tip, that is responsible for making plants cells elongate. The side in shadow therefore elongates while the side in full Sun does not. This turns the plant growth towards the Sun.
Comparition and contraction between phototropism and gravitropism?
If I am not mistaken, phototropism is when plants grow towards the sun. Gravitropism is when plants grow towards the ground.
What promotes plant growth and phototropism?
auxins

What is the three kinds of tropism?
Phototropism- response to ligh Gravitropism- response to gravity Thigmotropism- the third tropic response to heat
A plant sits on a window sill over time the stems of the plant curve toward the light coming in the windowThis process is called A phototropism B photoperiodism C gravitropism D phytochromism?
Phototropism
What is phototropism what does have to do with plants?
Tropism is the growth response of a plant caused by a stimulus. Gravitropism is the growth response of plant to gravity. The roots grow downward towards gravity, which is called positive gravitropism. The stem and upper part of a plant grow upward, away from gravity, which is called negative gravitropism.

Who discovered gravitropism?
Charles Darwin and his son did an experiment in 1880 using grass plants which led to the discovery of phototropism, this discovery led to many other scientists wanting to find out other tropisms
A grapevine coiling around a fence post is an example of?
Choose yourself A. Positive gravitropism B. positive thigmotropism C. Negative phototropism D. All of the above
