Question

Give examples of each :-
1- Geotropism
2- Hydrotropism
3- Phototropism
4- Thigmotropism
5- Traumatotropism
6- Chemotropism
7- Galvanotropism​

Answer 1

geo trophism-growth of bigger blant towards down the curvature or earth and growth of roots down wards

hydrotrophism-growth of roots twards water

phototrophism-growth of shoots of a plant twards sun

thigmotrophism-growth of crepper plants and money plant around a support ie rope

chemotrophism -growth of roots twards fertilisers

other 2 i don't know

Answer 2

1 geotropism movement of roots downwards due to gravitational force

2 hydrotropism movement of parts of plant in response to water

3 movements of plant towards light due to auxin (to know more refer TB)

4 thigmotropism movemet of plant due to motion

5 traumatroptism modification in plants root due to wounding

6 galvanotroprism motion due to electric field in a plant
7 chemotropism chemical stimulus as seen in pollen tube growth
