What is the Difference Between Dermal Tissue and Ground Tissue?
🆚 Go to Comparative Table 🆚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:
Feature | Dermal Tissue | Ground Tissue |
---|---|---|
Role | Protection and prevention of water loss | Food storage, photosynthesis, support, regeneration, and protection |
Location | Outermost layers of cells | Between vascular and dermal tissues in nonwoody parts of plants, and beneath the epidermis in stems and leaf petioles |
Types of Cells | Parenchyma cells | Sclerenchyma, collenchyma, and parenchyma |
Composition | Primarily the epidermis, composed of flattened polygonal cells | Primarily composed of sclereids, fibers, and guard cells |
Functions | Transpiration, gas exchange, and defense | Serves as a site for photosynthesis, provides a supporting matrix for the vascular tissue, and helps to store water and sugars |
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.
