Give the scientific terms used to represent the following (a) Bending of a shoot towards light.
(b) Growing of roots towards the earth.
(c) Growth of a pollen tube towards ovule.
(d) Bending of roots towards water.
(e) Winding of tendril around a support.
Answers
Answer :
Bending of shoot towards light - phototropism
(Photo = light,tropism = movement)
Growing of roots towards earth - geotropism.
(This means that plant respond positively for gravitational force.)
Growing of pollen tube towards ovule - chemotropism
Bending of roots towards water - hydrotropism
(hydro=water)
Winding of tendril around a support - thigmotropism.
(Tendrils are thin thread like growths on the leaves or stems of climbing plant.They grow towards support and wind around them.)
