Summary Introduction

Introduction :

Plants have many different tissues with specific function in different parts. They function together to provide food production and storage; give flexibility, support, and strength to the plants. The plant tissue include meristematic tissue that involve in producing new cells throughout the lives of a plant, dermal tissue that is also considered as epidermis, it form cuticles that help to reduce loss of water. There is one more tissue found in plants that are ground tissues. They include the tissues that are neither vascular nor dermal. They are involved in the storage of carbohydrates of the plants. They are divided into three categories that are parenchyma, collenchyma and sclerenchyma.

Explanation of Solution

There are three types of ground tissue; parenchyma, collenchyma and sclerenchyma. They function together to provide food production and storage; give flexibility, support, and strength to the plants. Parenchyma is the most flexible and thin cell found in the plants. They are responsible for the structure of plants and have much other function like food storage, gas exchange, photosynthesis, and protection. The next cell is collenchyma; they are cylindrical in shape and give support around the cell. They consist of unevenly thickened cell walls. This cell retains the ability to process cell division ones get matured. The third cell is the sclerenchyma; they are lack of cytoplasm and other living components ones get mature. They have thick and rigid cell wall; they involve in providing support to the cell and also help in transportation of materials within the cell. Therefore, it is not possible for a plant to survive in the absence of ground tissue.

Conclusion

The ground tissues function together to provide food production and storage, give flexibility, support, and strength to the plants. Therefore, it is not possible for a plant to survive in the absence of ground tissue.
