Answer:
Explanation:
1. The beam emitted travels along a straight path and it is divergent in nature. It has its radius increasing progressively as the distance away from the source of light increases.
2. It would be observed that the region where the bulb is positioned has denser light beam. This gets fainter towards the edges of the beam and away from the bulb.
In plant seeds, the photoreceptor phytochrome is responsible for the process termed photomorphogenesis<span>. This occurs when a seed initially situated in an environment of complete darkness is exposed to light. A brief exposure to electromagnetic radiation, particularly that whose wavelength is within the red and far-red lights, results in the activation of the photorecepter phytochrome within the seed. This in turn sends a signal through the signal transduction pathway into the nucleus, and triggers hundreds of genes responsible for growth and development</span>
