Question

The survival of plants in the terrestrial environment has been made possible by the presence of

• A. Intercalary meristem
• B. Conducting tissue
• C. Apical meristem
• D. Parenchymatous tissue

Answer 1

The correct option is B

Conducting tissue

The correct option is B.

Explanation for correct answer:

1. Conducting tissue is a group of cells that are responsible for transporting food particles and water molecules.
2. There are two types of conducting tissues in plants - xylem and phloem.
3. Xylem is responsible for conducting water to different parts of the plant body while the phloem is responsible for the transport of food particles.

Explanation for incorrect option:

Option A:

1. The intercalary meristem is the primary meristematic tissue that helps the plant grow vertically.
2. The cells present in this region are thin-walled, totipotent, and filled with protoplasm.
3. They are mitotically active and mature into permanent tissues.

Option C:

1. Apical meristem refers to the region of cells that are capable of division and growth in root and shoot tips.
2. They give rise to the primary plant body and are responsible for the extension of roots and shoots.

Option D:

1. Parenchyma is a simple permanent tissue that forms a major part of ground tissues.
2. It is non-vascular and is composed of undifferentiated cells that are modified to conduct specific cellular functions.

Final answer: The survival of plants in the terrestrial environment has been made possible by the presence of conducting tissues.
