phototropism
vernalization
Phototropism is the growth of plant, bacteria and certain animals towards a source of light.
Vernalization is the plant’s ability to flower by a prolonged chilly period in the spring. Gibberellins can replace the requirement for chilling temperature for flowering.
Phototropism can be negative or positive. Organisms growing in the direction of light are said to exhibit positive phototropism and those growing away from light are known to be exhibiting negative phototropism.
Vernalization does not induce the flowering in plant but rather prepares it for flowering.
Phototropism is an action of plant hormones. Auxin causes cells in the shaded region to elongate and therefore leads to bending of plant in the direction of light
Vernalization occurs due to vernalin which causes synthesis of florigen and therefore flowering.
