- A tissue is a group of cells having a common origin and usually performing a common function.
- The plant is made up of different kinds of tissues.
- Plant tissues are broadly divided into two main groups, namely, meristematic and permanent tissues based on whether the cells being formed are capable of dividing or not
Explanation:
- Meristem: A meristem is a group of cells that remain in a continuous state of division or retain their power of division. It is actively dividing cells.
- Parenchyma: It performs the function of storage of reserve food materials and storage of water in succulents. It also plays an important role in the buoyancy and gaseous exchange in water plants.
- Collenchyma: It is the chief supporting tissue in young dicotyledonous stems. The tissue has the capacity to expand and gives tensile strength to the body
- Sclerenchyma: It consists of thick-walled dead cells. It consists of fibers and Sclereids. Sclereids are short and possess extremely thick lamellated lignified walls with long tubular simple pits.
- Epidermal tissue: The tissue originates from the outermost layer of the apical meristem. It has epidermis, cuticle, and wax, Stomata, Trichomes. Singular of stomata is stoma. A typical stoma is microscopic and usually consists of two kidney-shaped guard cells surrounding a pore.
- Therefore, the correct answer is option 2, i.e., A - iii, B - i, C - ii, D - v, E - iv.
