What is the scientific term associated with plant growth to or away from a stimulus?
The general term for this behavior is tropism. It can take a variety of forms, including phototropism (when the stimulus is light) and chemotropism (when the stimulus is a particular chemical).
What are chemo tropism and hydro tropism?
Chemotropism : The movement of plant parts in response to chemical stimulus is called chemotropism. example- formation of pollen tube by pollen grains in order to transfer male gamete to the ovary. Hydrotropism : The movement of plant parts in response to water is called hydrotropism. example- movement of roots in search of water.
What are the examples of chemotropism?
Growth of pollen tube towards the ovule!
Signal to which an organism responds?
stimulus
Is stimulus a reaction to an internal event?
A stimulus is not a reaction, a stimulus is what causes a reaction.
What is is the stimulus chemotropism?
chemical
What is meant by chemotropism?
Tropism is defined as the movement, generally by a plant, due to outside stimuli; direction of sunlight being a primary stimulus. Chemotropism is defined as oriented growth or movement in response to a chemical stimulus.
What is the definition of chemotropism and what exhibits it?
Movement or growth of an organism or part of an organism in response to a chemical stimulus.

What are plants that has chemotropism?
Any plant can have chemotropism. Its all dependent on its reaction toward or away from chemicals. A Common example is pollen tubes and ovules.
What are the examples of chemotropism?
Growth of pollen tube towards the ovule!
Signal to which an organism responds?
stimulus
What is the different between an external stimulus and an internal stimulus?
The difference between an external stimulus and an internal stimulus is that an external stimulus is a stimulus that comes from outside an organism. But an internal stumulus is a stimulus that comes from inside an organism. An example for an external stimulus can be that when you are cold, you put on a jacket. An example for an internal stimulus is that when you feel hungry, you eat food.
What are the four tropisms?
Tropism is a biological phenomenon where an organism responds to the stimulus brought by the environmental factors. Some examples include: chemotropism, heliotropism, phototropism, thermotropism and electrotropism.
Is stimulus a reaction to an internal event?
A stimulus is not a reaction, a stimulus is what causes a reaction.
In positive feedback the initial stimulus produces a response that the stimulus?
exagerrates the stimulus
