Question

If the tip of the sugarcane plant is removed from the field even then it keeps on growing in length it is due to the presence of?

• A. Cambium
• B. Apical meristem
• C. Lateral meristem
• D. Intercalary meristem

Answer 1

The correct option is D

Intercalary meristem

The correct option is D.

Explanation for the correct option:

Option D:

1. Sugarcane is a monocot plant with intercalary meristems at the nodes.
2. As a result, the intercalary meristem found at nodes enables the sugarcane to develop even if its tip is severed.
3. An intercalary meristem is a stem that is found at the base of leaves or nodes that causes an organ's length to increase, such as leaves and internodes.
4. They are in charge of the plant's longitudinal growth, which accounts for the sugarcane's continuously extending length.
5. The internode's length is lengthened by the division of the intercalary meristem.
6. When a root or shoot lengthens, the apical meristem at the node sheds some meristematic cells.
7. Intercalary meristems are the names given to these meristems.
8. They are equivalent to apical meristems in capability.

Explanations for the incorrect options:

Option A:

1. After the tissues of the basic plant body have differentiated, the secondary meristems known as the vascular cambium and cork cambium form in the stems and roots of plants.
2. The vascular cambium is in charge of developing woody tissue and expanding the diameter of stems and roots.
3. The cambium is in charge of making wood and inner bark to thicken the plant.

Option B:

1. The root and shoot tips of plants have an area of cells called the apical meristem, which is capable of cell division and growth.
2. The major plant body and the growth of the roots and shoots are produced by apical meristems.
3. The terminals of a plant's roots and shoots include an apical meristem, a collection of cells that can divide and grow.
4. The development of the primary plant body and the extension of the root and shoot systems are carried out by apical meristems.

Option C:

1. The vascular and cork cambiums make up secondary, or lateral, meristems, which are present in all woody plants and some herbaceous ones.
2. In stems and roots, they form secondary tissues from a ring of the vascular cambium.
3. Secondary growth, which is characterized as an increase in stem girth and thickness, is brought on by secondary meristems, also referred to as lateral meristems.

Final answer: If the tip of the sugarcane plant is removed from the field, even if it keeps on growing in length, it is due to the presence of an intercalary meristem.
