What is the Difference Between Dermal Tissue and Ground Tissue?

The main difference between dermal and ground tissue lies in their location, function, and cell types. Here is a comparison of the two:

Dermal Tissue:

• Covers the outside of a plant in a single layer of cells called the epidermis.
• Its main functions are transpiration, gas exchange, and defense.
• Composed of a single layer of epidermis cells, which may contain stomata and guard cells for gas exchange.
• Primarily consists of parenchyma cells.
• In roots, it helps in water and ion uptake, while in leaves and stems, it regulates gas exchange.

Ground Tissue:

• Makes up most of the interior of a plant and carries out basic metabolic functions.
• Stores food, water, and provides support.
• Composed of three types of cells: sclerenchyma, collenchyma, and parenchyma.
• Responsible for photosynthesis, support, regeneration, and protection.

In summary, dermal tissue covers the outside of a plant and is primarily involved in protection, transpiration, and gas exchange, while ground tissue makes up the interior of a plant and is responsible for basic metabolic functions, storage, and support.

Comparative Table: Dermal Tissue vs Ground Tissue

Dermal tissue and ground tissue are two of the three main types of plant tissues, which also include vascular tissue. Here is a table highlighting the differences between dermal tissue and ground tissue:

Dermal tissue is responsible for covering and protecting the plant, while ground tissue is involved in various functions such as photosynthesis, support, regeneration, and protection.
