1Write the following items about the experiment you have done to show that plants move to light.
a) Used equipments b) Method of the experiments c) Observed results.
A. a) Used equipments : Glass jar filled with soil, bean seed
b) Method of experiment:
Take a glass jar and fill with soil. Sow a bean seed near the wall of the jar. This helps us to observe how root and shoot are growing. After 4-5 days we will notice seed germination. Keep the jar under the sun - observe how root and shoot grows. Then fill the glass jar and keep the plant horizontally. Observe the direction of root and shoot growth for more than a week.
c) Observed results:
The shoot position (tip) of the plant grows towards light. It bends towards light. It is due to collection of more auxin on the light illuminated side of the stem. So cells on that side grow faster. On opposite side cells grow slow to make the stem bend.
