Answer:
Option-B
Explanation:
Phototropism refers to the movement of plants in response to light. The mechanism of phototropism involves the photoreceptors which respond to a different wavelength of light: the phytochromes to red light, cryptochromes to blue light and the phototropin to the UV light.
Plants integrate the signals obtained from these receptors and then activates the gene which will be involved in the phototropism.
The gene could be the production of the auxin hormone and the PIN proteins which helps in the distribution of the auxin in the plants. Due to the production of this hormone and its distribution in the shoot, the grass tips bend towards the light.
Thus, Option-A is correct.
Simple carbohydrates are found naturally in foods such as fruits, milk, and milk products. They are also found in processed and refined sugars such as candy, table sugar, syrups, and soft drinks.
