Question

We took glass jars and filled them with water. Now, Took two onion bulb and place one on each jar. a) What will be the observation in the roots of the onion after 2 to 4 days? b) What tissue is present in the tip of the root? c) Where is this tissue present other than tips of roots? d) What happens if the tips of the roots cut?​

Answer 1

Step-by-step explanation:

a)When glass jars are filled with water and onion bulbs are placed inside, small white roots will emerge from the bottom of each onion bulb within 2 to 4 days. These roots will continue to grow longer as time passes.

b)The tissue present in the tip of the root is known as the apical meristem. This particular region is responsible for cell division and the growth and development of the root.

c)Apart from being present in the tips of roots, the apical meristem tissue can also be found in the tips of shoots in all plants. It plays a crucial role in the growth of the plant's length.

d)Cutting the tips of the roots will temporarily halt the growth of the roots as the apical meristem is removed. However, the plant will eventually develop new apical meristems and resume growing. This may affect the growth rate of the plant, and the root system may become more branched.
