• The epidermal cells of the roots give out fine hair-like outgrowths called the root hairs that absorb water and minerals

Pisum sativum, also called pea plant has nodulated roots because they are found in association with a nitrogen-fixing bacterium called Rhizobium. This rhizobium resides in these nodules.

• Vegetative parts of the plant include roots, stem, leaves 

The ability to bend and growing the root towards a moisture gradient is essential because plants need water to grow. Water, together with soluble mineral nutrients, is taken up by the root hairs. Then, in vascular plants, water and minerals are transported to all parts of a plant through a lignified transport system called as xylem. The second transport system in vascular plants is called as phloem. The phloem also carries water, not with soluble minerals, but mainly with soluble organic nutrients instead. These organic nutrients are delivered by photosynthesis and are called as photosynthate. 

A. Adventitious roots are the roots which are produced from other plant parts like stems, leaves etc.

Root cap takes part in the protection of root meristem because it is the layer separating the meristem from the external forces. It protects the tender apex while root makes its way into the soil.
