Two glass jars filled with water are taken. Two onion bulbs are taken and placed in each of
the jars. Observe the growth of roots in both the jars. Measure the length of the roots daily.
On Day 3 cut the root tips of the onion in Jar 2 by 1 cm and measure their lengths each day
for 2 to 3 more days. By this activity, above Table was constructed.
2.1 Does the root of onion in Jar 2 continue growing even after its tip is removed? [1]
2.2 Why does it stop growing after the root tip is removed? (1)
2.3 What is apical meristem and what is its function? [2]
2.4 What happens to the cells formed from meristematic tissue and by which process they
are formed? (1)​

Answer 1

Answer:

2.1 no it stops growing

2.2 it stopped growing because it lost its root apical meristamatic tissue

2.3 apical meristem is the tissue which is in process of continuous division and helps in increasing the length of both stem and root.

2.4 some of the cells loses its meristematic activity while some retains and continues division .They becomes permanent tissue by the process of differentiation

Explanation:

these are the explanations
