Question

The significance of boiling the leaf in water during a starch test is known _____________.

• A. To remove waxy cuticles
• B. To rupture cytoplasm
• C. To rupture starch molecule
• D. None of the above

Answer 1

The correct option is A To remove waxy cuticles

A cuticle is a waxy layer that is mainly present above, the epidermis and aerial parts of the plant. It makes the cell nearly impermeable.

During the test of starch in the leaves, the leaf is boiled in order to dissolve or denature the waxy cuticle so that the chemicals like potassium Iodide can easily enter into the cell and provide an accurate estimation of starch.

So, the correct answer is 'To remove waxy cuticles'.
