  2. False

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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. 

So, the correct answer is 'True'.

Primary roots and its branches constitutes to

  1. Adventitious root system

  2. Tap root system

  3. Fibrous roots

  4. Seminal roots

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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

B. Taproot system is the root system where the root develops from the radicle producing primary roots and its branches secondary roots. Here the radicle persists.
C. Fibrous roots are the roots which are short and appear as a bunch when the radicle is absent.
D. Seminal roots are temporary roots which are present during ungerminated caryopsis.
So, the correct answer is 'Tap root system'.

Root cap takes part in

  1. Formation of new cells

  2. Absorption of water and minerals

  3. Protection of root meristem

  4. Storage of food

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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.

So, the correct option is 'Protection of root meristem'.
