Anatomy of Root

Q.

In roots of plants, the root hairs are covered by a very thin ___.

1. They differentiate to form permanent tissue.

2. They initiate plant growth.

3. None of the above.

4. They form permanent tissue which can divide.

Q.

Which of the following criteria is used to categorise plant tissues into meristematic and permanent tissue?

1. Capacity to do photosynthesis

2. Capacity to divide

3. Capacity to move

4. Complexity to perform a function

Q.

How fast do hair roots grow?

Q.

The basic principle based on which we categorize plant tissues as meristematic and permanent is:

1. capacity to do photosynthesis

2. capacity to divide

3. capacity to move

4. complexity to perform a function

Q.

Find the correct sets from the following.
$\begin{array}{ccc}\text{Type of meristematic tissue}& \text{Location}& \text{Function}\\ \text{i. Apical meristem}& \text{Tip of stem and roots}& \text{Increase in length}\\ \text{ii. Lateral meristem}& \text{Laterally placed inside stem and root}& \text{Increase in girth}\\ \text{iii. Intercalary meristem}& \text{Base of leaves and internodes}& \text{Growth of leaves and stem}\end{array}$

1. Only i is correct
2. Both i and ii are correct
3. Both i and iii are correct
4. All i, ii and iii are correct
