Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why are vascular bundles arranged around the edge in the stem?
A
To give a shorter diffusion distance
B
To give strength and support
C
To allow growth
D
To leave space for sugars to travel up the middle of the stem
Explanation: 

Detailed explanation-1: -Xylem vessels are tough and strong, so the vascular bundles are in the centre of the root to resist forces that could pull the plant out of the ground.

Detailed explanation-2: -The vascular bundles in the stem are arranged around a ring of cambium, which contains cells that divide to expand the girth of the stem. This is similar to the function of the cambium in dicot roots.

Detailed explanation-3: -Plant vascular tissues provide physical strength to plant bodies and transport water, nutrients and other substances required for growth and defense. They interconnect all the plant body parts by their conductive function, from the root tip to the various organs in the shoot.

Detailed explanation-4: -Vascular bundles play important roles in transporting nutrients, growth signals, amino acids, and proteins between aerial and underground tissues.
