- <u>Phototropism</u> is the process in which plant grow in response to light. Where "Photo'' means light and ''Tropisms'' are responses to external stimuli in this case stimuli against light.
Now, going back to the question
- Plant cells grows faster in the presence of the hormone auxin.
- As a result when a plant senses a light from a direction, auxin molecules accumulates to the side that is further away from the light, due to which the plant cells that are further away from the light experience a greater auxin concentration and grow faster, due to which shoot gets bend towards the direction of the applied light.
- <u>Gravitropism</u> is a process of growth by a plant in response to gravity pulling on it. Roots show positive gravitropism i.e they will grow with the gravitational pull and stems show negative gravitropism that is they will grow against gravitational pull.
- Auxin is a plant hormone which promotes stem elongation and inhibits the growth of lateral buds.
- Auxin helps in maintaining apical dominance, which means in presence of auxin the plant will grow Vertically upward i.e against the gravity. Hence Auxin promotes gravitropism.
Result: Phototropism and Gravitropism is controlled by Hormones
The neurotransmitter that is primarily associated with the feeling is dopamine.
<h3>The effects of neurotransmitters</h3>
Neurotransmitters are the chemicals that transmits messages in the form of chemical signals from nerve cells to target organs.
Examples of neurotransmitters include the dopamine. This is the neurotransmitter that is primarily associated with the feeling of wanting something. This is because it fulfills the following roles in the brain:
Therefore, the neurotransmitter that is primarily associated with the feeling is dopamine.
