Geotropism

Important Notes to Know:

• Geo in the word geotropic revers to gravity and tropic as in growth response so geotropic means gravitational growth response. 
• Roots growing down a seed is called positive geotropism.
• Embryonic shoot of a plant growing up towards the soil is called negative geotropism.
• If the germinating seed is rotated the roots will still grow downwards because of geotropism. 
• If the germinating seed is rotated the Embryonic shoot will grow upwards because of geotropism.
