Question

Figure of hydathode has a labelling. Which of the following match is correct?

• A. a - Guard cell, b - Apithem, c - Mesophyll, d - Epidermis, e - Vasculature
• B. a - Guard cell, b - Epidermis , c - Mesophyll, d - Apithem, e - Vasculature
• C. a - Water pore, b - Epidermis , c - Mesophyll, d - Epithem, e - Vasculature
• D. a - Ostoile, b - Epidermis , c - Mesophyll, d - Epithem, e - Vasculature

Answer 1

Answer: (C)

a - Water pore, b - Epidermis , c - Mesophyll, d - Epithem, e - Vasculature

It is the diagrammatic sketch of hydathodes.

A is the water pore in the epidermis layer which helps in the exchange of water.

B is the outermost layer of cells is called 'epidermis'.

C is the mesophyll cells of hydathode which are responsible for photosynthesis.

D is epithem which helps in guttation.

E is the vasculature which is the arrangement of vascular bundles to which passive hydathodes are attached.

So, the correct answer is option C.
