Question

The apical meristem is a region of undifferentiated cells located at the tips of all roots and shoots. For instance, division of cells in the apical meristem add cells to the root, and as those cells grow, they increase the length of the root. Predict the result if the apical meristem cells from a shoot were removed and then grafted onto a mature region of a shoot.
Drag the phrases on the left to the blanks on the right to complete the sentences. Not all phrases will be used.

1. The shoot region in which the apical meristem cells were removed will _____________
2. The mature region in which the apical meristem cells were grafted will ___________

Answer 1

Answer:

1. Will not grow

2. will grow and will form new root

Explanation:

Meristematic tissue is the tissue formed by the undifferentiated cells which can form new tissues. The meristematic tissue present at the tip of root and shoot is known as apical meristem.

In the given question, if the apical meristem is removed from the shoot then the shoot from which the meristem will not grow and the shoot on which the meristem will be grafted will form the new shoot due to the ability of the meristematic cells to divide.

Thus, Will not grow and will grow and form new root are correct.
