Comparition and contraction between phototropism and gravitropism?
Wiki User
∙ 14y ago
If I am not mistaken, phototropism is when plants grow towards the sun. Gravitropism is when plants grow towards the ground.

What is the difference between Hydrotropism and phototropism?
Hydrotropism is a plant's growth reaction in which the path of growth is formed by a gradient or stimulus in water concentration. Phototropism commonly occurs in plants but can also take place in other beings like fungi.
When was the link between muscular contraction and electricity discovered?
1771 by Ludwig Galvani
What is a jar with its lid on tightly an example of?
Thermal expansion and contraction, specifically the different coefficients of thermal expansion (CTE) between glass and metal....AND ITS LIKE A (CLOSED SYSTEM)
What is the difference between wave summation and recruitment?
Wave summation releases more calcium and increases the force of contraction by increasing the firing rate of motor neurons (The second contraction takes place before the first is completely at rest) so each stimulation adds up. This is all within ONE MUSCLE FIBER. Recruitment is the calling up multiple MOTOR UNITS, in order to increase the force of contraction. t has a size principle (those with small diameters, the more delicate ones are called first, then the larger and so on.) There is no added calcium ions as in wave summation. They usually occur together. wave summation can cause tetanus, while recruitment cannot.
How does large variations between day and night temperatures cause weathering?
During the warm day, things expand from the increased heat. During the cold night, things contract as heat is lost. This process of expansion and contraction creates cracks and other stress points that cause weathering.Hence the temperatures cause weathering. Note: There are few substances that this expansion and contraction can be seen with the naked eye, but even the minute changes cause weathering, and when substances like water get into the microscopic cracks then freeze, it magnifies the effects as water expands when it freezes while other substances contract when they cool down.
What is the relationship between auxin and phototropism?
Phototropism is the biological process for auxin's.
What is the difference between phototropism and geotropism?
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 is the difference between isotonic and isometric contractions?
An Isotonic muscle contraction is a muscle contraction that makes your limbs move whereas an Isometric contraction is a muscle contraction where the limbs stay static
What is the difference between contraction and expansion?
In contraction the size of item becomes smaller. In contract, expansion increases it.
What type of muscle contraction will shorten a muscle and decrease the angle between two bones?
Concentric isometric contraction
Why there are spaces between bridges?
To allow for expansion and contraction.
What is the difference between Hydrotropism and phototropism?
Hydrotropism is a plant's growth reaction in which the path of growth is formed by a gradient or stimulus in water concentration. Phototropism commonly occurs in plants but can also take place in other beings like fungi.
What is the contraction of it is?
The correct contraction of "it is" is "it's". Some people often get confused between "it's" and "its". It's is the contraction of it is, whereas its is possessive. For example, the cat is wagging its tail as it's walking.
What is the relationship between the load on a muscle and its strength of contraction?
Strength of contraction increases as the load increases until the load becomes excessive.
What is the Relationship between a load on a muscle its strength of contraction?
Strength of contraction increases as the load increases until the load becomes excessive.
Why are the gaps between adjoining rails?
To allow for expansion and contraction.
