Answer :
Answer: Forms of tropism include phototropism (response to light), geotropism (response to gravity), chemotropism (response to particular substances), hydrotropism (response to water), thigmotropism (response to mechanical stimulation), traumatotropism (response to wound lesion), and galvanotropism, or electrotropism
Explanation:
Tropism is a response to certain stimuli. A positive tropism is moving towards the stimuli, while a negative tropism is moving away from a stimuli.
Positive Phototropism - Growing towards light
Positive Thigmotropism- Moving towards touch
Positive Hydrotropism - Growing towards water
Positive Gravitropism - Growing towards ground
