It is because conducting tissue help plants to grow or devlop in any climate .

Introduction:
Survival of plants in terrestrial environments is made possible by a combination of various adaptations. One of the key adaptations is the presence of conducting tissue.

Explanation:
1. Conducting tissue:
Conducting tissue refers to the specialized tissues in plants that are responsible for the transport of water, nutrients, and organic compounds throughout the plant body. It consists of two main types of tissues: xylem and phloem.

2. Xylem tissue:
Xylem tissue is responsible for the transport of water and minerals from the roots to the aerial parts of the plant. It is composed of several cell types, including tracheids and vessel elements. These cells are dead at maturity and form continuous tubes or vessels that facilitate the movement of water through the plant. Xylem tissue also provides mechanical support to the plant.

3. Phloem tissue:
Phloem tissue is responsible for the transport of organic compounds, such as sugars and amino acids, from the leaves to other parts of the plant. It is composed of sieve tube elements and companion cells. Sieve tube elements form long tubes that allow the movement of organic compounds, while companion cells provide metabolic support to the sieve tube elements.

4. Importance of conducting tissue in terrestrial plants:
The presence of conducting tissue is crucial for the survival of plants in terrestrial environments due to the following reasons:

a) Water transport: Xylem tissue facilitates the transport of water and minerals from the roots to the aerial parts of the plant. This is essential for the maintenance of plant turgidity, photosynthesis, and nutrient uptake.

b) Nutrient transport: Phloem tissue enables the transport of organic compounds, such as sugars, from the leaves to other parts of the plant. These compounds are required for energy production and growth.

c) Long-distance transport: Conducting tissue allows plants to transport water, nutrients, and organic compounds over long distances, from the roots to the shoots and vice versa. This is especially important for tall terrestrial plants, as it helps in maintaining a steady supply of resources throughout the plant body.

d) Structural support: Xylem tissue provides mechanical support to the plant, helping it to withstand the forces of gravity and wind. The presence of conducting tissue ensures the proper distribution of water and nutrients, which is essential for the overall structural integrity of the plant.

Conclusion:
The presence of conducting tissue, composed of xylem and phloem, plays a vital role in the survival of plants in terrestrial environments. It facilitates the transport of water, nutrients, and organic compounds throughout the plant body, ensuring proper growth, metabolism, and structural support.
