Question

Identify the dissimilarity between monocots and dicots.

• A. Monocot embryos form two leaves, dicot embryos form a single leaf
• B. Monocot flowers may consist of five petals, dicot flowers may consist of six petals
• C. Monocot leaves have a branching network of veins, dicot leaves have parallel veins
• D. Monocot roots consist of many small roots growing from a taproot, dicot roots lack a taproot
• E. Monocot vascular tissue is arranged randomly in the stem, dicot vascular tissue is arranged in a ring

Answer 1

The correct option is E Monocot vascular tissue is arranged randomly in the stem, dicot vascular tissue is arranged in a ring

The flowering plants or Angiosperms are classified into two groups monocots and dicots on the basis of the nature of embryo in the seed. In monocots , the vascular tissue is scattered throughout the stem with no particular arrangement and has no cortex. It has single cotyledon in seeds and parallel venation in leaves. Whereas, in dicots, the vascular tissue is arranged in a ring and is divided into a cortex and stele. It has two cotyledons in seeds with reticulate venation in leaves.

Thus, the correct answer is option E.
