Root System

1) Which Cells of the Roots Divide Fast and Why?

• The cells present at the tip of the root cap divide very fast.
• The root cap is the region at the end of the growing tip of a root.
• These cells divide at a more rapid pace to ensure the penetration of the roots to the deeper layers of soil.

2) Why Do Water and Minerals Travel Only Upwards in Roots and Shoots and Not in the Opposite Direction?

• Water and minerals are conducted in the upward direction due to transpiration pull.
• When water evaporates from the leaves, a suction force originates that pulls water from roots and stems upwards
