Question

Select which option correctly Identifies if the following cross section of a stem is a monocot or a dicot and explains the correct reason why.

A. dicot because the vascular bundles are arranged randomly
B. monocot because the vascular bundles are arranged randomly
C. monocot because the vascular bundles are arranged in a pattern
D. dicot because the vascular bundles are arranged in a pattern

Answer 1

Answer: The following cross section of a stem is a monocot because the vascular bundles are arranged randomly. Correct option is B.

Step-by-step explanation:

The flowering plants form the largest group in the plant kingdom. They are more highly evolved than gymnosperms because they have an abundance of water and food conducting vessels known as the VASCULAR BUNDLES..

The angiosperms are grouped into two namely:

---> Dicotyledons and

--> MONOCOTYLEDONS: These are the most advanced plants. They tend to be more efficient and specialised because they have fewer parts. As such they show a very high degree of adaptation to their environment. The VASCULAR BUNDLES which is defined as the conducting vessels (transport system) made up of xylem and phloem, are arranged randomly. The xylem is the water conducting tissue which also had a strengthening function while the phloem is the transports organic molecules ( food). The vascular bundles are scattered because they lack cambium and therefore do no undergo secondary growth.
