Phototropism - towards light. Think plants, flowers, leaves. They generally turn towards light.
Geotropism - towards the earth. Go figure.
Hydrotropism - towards water or towards moisture.

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
A plant seedling grows toward the window and its roots reach into the soil what type of movement does the seedling show?
These growth responses are called tropisms. Growing towards the light is called phototropism, and towards the source of gravity is geotropism.
What is a sentence example of phototropism?
We observed the phototropism of our plants.
What do phototropism and geotropism enable plants to do?
Grow in the correct direction of the resource needed.
Does geotropism determine the direction of growth?
Yes, geotropism DOES determine the direction of growth. Negative geotropism is when a section of the plant grows upwards. For example, stems grow upward. Positive geotropism is when a section of the plant grows downwards. In this case, a plant's roots would be the perfect example.
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
Stems and leaves grow using positive what?
stems and leaves grow using positive phototropism. That means growing towards the source of light. Mostly we reffer to the sun in this case. Even so, stems and roots can as well grow away from the source of light, that is negative phototropism.
Do animals also show phototropism and geotropism give examples?
only plants no animals
What are 4 examples of tropism?
geotropism (also known as gravitropism), phototropism, and hydrotropism.
What are kinds of tropism?
phototropism-responce to llight geotropism-responce to gravity thigmotropism-responce to touch hydrotropism-responce to water
The name of the response of plants to light?
a "tropism"; geotropism for response to gravity and phototropism for response to light
What is the name of the reaction?
response to water: hydrotropism, response to light: phototropism, response to chemicals: chemotropism, response to gravity: geotropism, response to touch: thigmatropism
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
What is the main stimuli affecting the growth of the shoot of the plant?
light, positive phototropism and towards the light gravity, negative geotropism and grow in opposite direction to gravity NOT WATER
What is the relationship between auxin and phototropism?
Phototropism is the biological process for auxin's.
Which response is result of geotropism?
Growth of plants toward the light is called phototropism. Growth of plants in response to gravity is called geotropism or gravitropism.
What causes shoots and leaves to elongate?
Leaves and shoots grow towards light in a reaction known as phototropism. Similarly, an attribute called geotropism causes roots to grow down towards gravity.
