BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Phototropism is one of the many plant tropisms or movements which respond to external stimuli. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism (skototropism).

Detailed explanation-2: -When the plant has the ability to grow away from the light or they grow towards the darkness, this is called negative phototropism. For example-Vine and Arabidopsis.

Detailed explanation-3: -In the plant root, responses to light are known as a negative phototropism, which means the root grows away from the light.

Detailed explanation-4: -One important light response in plants is phototropism, which involves growth toward-or away from-a light source. Positive phototropism is growth towards a light source; negative phototropism is growth away from light.

Detailed explanation-5: -Examples: Curving of the stem toward sunlight (Positive phototropism) Movement of root away from the light inside the soil (Negative phototropism)
