Question

Given the diagram of L.S of a part of bark region of plant. Choose the answer with the correct combination of parts and alphabets.

• A. A = hydathode, B = epithem, C = phellem, D = phellogen, E = phelloderm.
• B. A = lenticular opening, B = cortex, C = phellogen, D = phellem, E = phelloderm
• C. A = stoma, B = secondary cortex, C = phellem, D = phellogen, E = phelloderm
• D. A = lenticular opening, B = complementary cells C = phellem, D = phellogen, E = phelloderm.

Answer 1

The correct option is D

A = lenticular opening, B = complementary cells C = phellem, D = phellogen, E = phelloderm.

The T.S. provided in the question is that of a dicot stem. The stem has cambium, which shows secondary growth. Here A is the lenticell opening, B is Companion cell, C is is Phellem, D is Phellogen and E is Phelloderm.
