Question

In a woody dicotyledonous tree, which of the following parts will mainly consist of primary tissues?

• A. Stem and root
• B. All parts
• C. Shoot tips and root tips
• D. Flowers, fruits and leaves

Answer 1

The correct option is C Shoot tips and root tips

The tissues which develop from apical meristem and procambium are known as primary tissues and these constitute the primary structures of the plant body. The development of the primary tissues causes the stem to grow in length and to some extent in thickness.
Stem and root in dicot shows secondary growth as they develop from secondary vascular tissues. Shoot tips and root tips are constantly proliferating since they help in the vertical growth and therefore, it consist of meristematic tissues.
So, the correct answer is option 'c'.
