Q.5 :-Monoxylic wood consists of
(A) compact wood
(B) soft-loose wood
(C) compact wood with abundant parenchyma
(D) soft-loose wood with abundant parenchyma​

Answer 1

Answer:

D) soft-loose wood with abundant parenchyma.

Explanation:

Manocylic woods have large piths and cortex and abundant parenchyma mixed with less amount of xylem tracheid. Thus they are non compact wood( soft-loose wood).

Answer 2

Answer:

(D) soft-loose wood with abundant parenchyma​

Explanation:

• The wood formed in a single ring of vascular bundles due to the persistent cambium is referred to as mono (single or one ring)xylic wood.
• Here the cambial activity is short-lived. The cortex and central pith are broad. The medullary rays are broad and parenchymatous.

• The wood is soft and non-compact which shows abundant parenchyma.

• Such type of wood is found in the young stem of Cycas.

Hence option D. is correct.
