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 difference between positive and negitve geotropism?
Geotropism (also called gravitropism) is the turning or growth movement by a plant or fungus in response to gravity. Roots show positive geotropism (grow toward gravity - down) and stems show negative geotropism (grow away from gravity - up).
Can you make a sentence using the word Geotropism?
geotropism mean to have fun doind the things
What is the growth of the plant part towards the earth called?
It is called geotropism.
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.
Is gravity a response to geotropism?
No
What is Geo-Tropism?
Geotropism is a plant growth or movement in response to gravity. Upward growth of the plant's parts against gravity is called negative geotropism, whilst downward growth of roots is called positive geotropism.
Gravitropism is also known as what?
geotropism
What is another name for geotropism?
earth root
What kind of tropism do roots have when they are in the soil?
Geotropism
How does geotropism help a plant survive?
geotropism is the ability of the plant to grow in he direction of gravity so if there isn't sufficient water available the roots of the plant due to geotropism go deeperinto the the earth so as to obtain some amount of water which will help them to survive
What is positive gvravitropism?
firstly there is no word as GVRAVITROPISM. When plants grow towards gravity it is called GEOTROPISM. its is mainly the root of plants that show geotropism; because they grow downward. but the stem show negative geotropism because it grows up in the opposite direction of gravity
