Question: Match the following and choose the correct option from belowColumn IColumn II A.Cuticlei.Guard cells B.Bulliform cellsii.Single layer C.Stomataiii.Waxy layer D.Epidermisiv.Empty colorless cell
Options:
A – iii, B – iv, C – i, D – ii
A – i, B – ii, C – iii, D – iv
A – iii, B – ii, C – iv, D – i
A – iii, B – ii, C – i, D – iv
Concept:
→ The epidermal tissue system forms the outer-most covering of the whole plant body and comprises epidermal cells, stomata, and the epidermal appendages – the trichomes and hairs.
→ The epidermis is the outermost layer of the primary plant body.
→ It is made up of elongated, compactly arranged cells, which form a continuous layer.
📝 Additional Information:
→ The cuticle is a waxy layer. It covers the upper or lower or both surfaces of leaves of plants that inhabit aquatic or xerophytic conditions.
→ Bulliform cells are empty colorless cells present in monocot leaves. It prevents water loss by rolling in during water stress.
→ Guard cells are present in stomata. A typical stoma is microscopic and usually consists of two kidney-shaped guard cells surrounding a pore.
→ The epidermis is composed of a single layer of cells.
📌 Important Points
→ Therefore, the correct answer is option 1, i.e., A – III, B – iv, C – I, D – II.
