Question

Where is the least specialized tissue located in plants?

Answer 1

Hint: The tissue system in plants is arranged into three types of tissue systems. The dermal tissue system, the ground tissue system and the vascular tissue system are the different types of tissues.

Complete answer : The three types of tissue system are important for the plants as the systems work in a coordinated manner to carry out the different biological activities in the plants.
The dermal tissue system includes the epidermis and the periderm that is present in the older stems and the roots of the plants. The main functions of the dermal tissue system is the protection and prevention of water loss from the different surfaces of the plants.
The vascular tissues are related with the transportation of water and minerals from the roots as well as transportation of water and food compounds from the leaves to the different parts of the plants. The vascular tissues include the xylem and phloem tissues and they are also called as the conducting tissues.
The ground tissue system is responsible for a variety of different actions. They are responsible for the process of photosynthesis, food storage, regeneration of the old and lost parts as well as provide support and protection to the plant.
 The dermal tissue system is made up of the parenchyma tissue, collenchyma tissue and the sclerenchyma tissue. The collenchyma tissue has thick secondary walls and they provide mechanical and structural support to the plant. The sclerenchyma tissue bears thick lignified walls and dead tissue when they mature. They provide hardness and strength to the plants.
The parenchyma tissues of the ground system are a tissue that helps to fill up the soft parts of the plants. They are often referred to as the filler tissues or the visceral flesh. It forms the outer region of the cortex and in the central region of the plants they form the pith. They also form the cortex of the roots, the mesophyll in leaves, and the pulp in the fruits and are also involved in the formation of endosperms in the seed. They are thin walled, large cells with flexible cellulose cell walls. They usually remain alive even after maturity.
The parenchyma are considered as the least specialised types of plant tissues. They are associated with different types of functions on the basis of their presence in different parts of the plant. They perform a variety of functions ranging from storing food, participating in photosynthesis, present in the roots as well as in the fruits.

Note: The parenchymal tissues are the least specialized tissues in plants and form the ground tissue system in plants. The parenchyma tissues are non-vascular in nature and are composed of simple and live cells which are not differentiated. They are also known as a group of functional tissues as they perform many functions in the plants. They are involved in performing several important tasks such as they make up most of the cells of leaves, flowers and fruits and are involved in photosynthetic activity, food storage etc. Thus, they are adaptable and related to a variety of functions.
