Question

Demonstrate the effect of light on seed germination, plant shoot growth and leaf colour
using material available in your surroundings. You can collect as much as information
on this topic and prepare a report in your own style.​

Answer 1

Answer:

Plants deprived of light will lose their color and die. The shoots exposed to “limited/no” sunlight had a yellow/white color due to the fact that photosynthesis could not occur. The lack of sunlight stunted photosynthesis and therefore the sprouts were not able to produce the chlorophyll needed to create a green color.

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.Most plants grow faster in the evening and at night than they do during the day. ... Plants can use the products of the days photosynthesis at night to aid in the uptake up water into their cells, which increases the turgor pressure of the cells and drives their enlargement.Day length is a little more complicated, especially in combination with temperature. ... Many plant species have day length triggers that determine when they grow vegetatively and when they bloom. They may be long-day plants or short-day plants. Some plants do not react to day length; they are called day-neutral.

Answer 2

Answer:

The effect of light on seed germination: Red colored light will increase the growth of seed and blue light will inhibit the growth of the seed.

plant shoot growth: sunlight, proper temperature, moisture, air, and nutrients. These are most important in the growth of plant.

leaf color:In the presence of light leaf color will be green otherwise it will be yellow due to lack of light.
