Lateral
Tap
Which one of the following depicts Tap Root System?
Which one of the following is a Fibrous Root System?
Which one of the following depicts Adventitious Root System?
The main functions of the root system is
absorption of water and minerals from the soil
providing a proper anchorage to the plant parts
storing reserve food material and synthesis of plant growth regulators
All of The Above
The root is covered at the apex by a thimble-like structure called the
Root Apex
Root Tip
Root Point
Root Cap
Which part protects the tender apex of the root as it makes its way through the soil
Root Apical Meristem
Root Apex
Root Cap
Root Stem
A few millimetres above the root cap is the
Region of meristematic activity
Region of Elongation
Region of Maturation
None of the Above
The cells of this region are very small, thin-walled and with dense protoplasm. They divide repeatedly
Region of Elongation
Region of Maturation
Region of Meristematic Activity
Region of Root Cap
The cells undergo rapid elongation and enlargement and are responsible for the growth of the root in length
Region of Root Cap
Region of Elongation
Region of Maturation
Region of Meristematic Activity
The cells of the elongation zone gradually differentiate and mature. Hence, this zone, proximal to region of elongation, is called the
Region of Development
Region of Differentiation
Region of Maturation
Region of Adulthood
From Maturation region some of the epidermal cells form very fine and delicate, thread-like structures called

Root Barnacles
Root Projections
Root Hairs
