Q. What is Hydrotropism give example?
Hydrotropism is a form of tropism characterized by the growth or movement response of a cell or an organism to moisture or water. An example of positive hydrotropism is the growth of plant roots towards higher relative humidity level.
Q. What is Hydrotropism in plants Class 10?
Hydrotropism is a plant growth response in which the direction of growth is determined by a stimulus gradient in water concentration a common example is a plant root growing in humid air bending towards higher relative humidity level.

Q. What’s the meaning of Hydrotropism?
: a tropism (as in plant roots) in which water or water vapor is the orienting factor.
Q. What is Hydrotropism and Chemotropism?
The movement of a plant (or other organism) either towards or away from water is called hydrotropism. An example is that of plant roots growing in humid air bending toward a higher relative humidity level. The movement of plant towards or away from chemicals is called chemotropism.
Q. What is the difference between Hydrotropism and Chemotropism?
Hydrotropism-is a plant ‘s growth response in which the direction of growth is determined by a stimulus or gradient in water concentration. Chemotropism-Chemotropismis growth of organisms (or parts of organism) such asbacteriaandplants, navigated by chemicalstimulusfrom outside of the organism.
Q. Which Tropisms do plants display?
gravitropism
Q. What is called Chemotropism?
Chemotropism is defined as the growth of organisms navigated by chemical stimulus from outside of the organism. Chemotropism is slightly different from Chemotaxis, the major difference being that chemotropism is related to growth, while chemotaxis is related to locomotion.
Q. Is Chemotropism positive or negative?
A positive chemotropism is one in which the growth response is towards the stimulus whereas a negative chemotropism is when the growth response is away from the stimulus. Chemotropism can be observed during the growth of the pollen tube towards the ovules.
Q. What is Chemotropism and give an example?
The growth of a plant part due to chemical stimulus is known as chemotropism or Chemotropism is the movement of a part of the plant in response to a chemical stimulus. The growth of pollen tube towards the ovule induced by a sugary substance as stimulus. This is an example of positive chemotropism.
Q. Why auxin is present in human urine?
why are auxins present in human urine?? Indole-3-acetic acid (IAA) has a metabolic reason for its generation in human body. It is formed by breakdown of serotonin, mainly in liver and then is excreted in the urine. Serotonin is a neurotransmitter synthesised from tryptophan, similar to how auxin is made in plants.
