Question

How many shoot aplical meristematic zones are expected in a twig of a plant possessing 9 branches, 39 leaves ?

• A. 9
• B. 39
• C. 10
• D. 8

Answer 1

The correct option is C 10

Shoot apical meristem is the region in the growing shoot containing meristematic cells. The shoot apical meristem contains multipotent stem cells and produces primordia that develop into all the above-ground organs of a plant.it is always present at the growing apices.

Plants having 9 branches and 39 leaves will have 10 growing apices i.e shoot apical meristematic zones (9 growing apex of the branches +1 growing apex of the main plant axis ).

So, the correct answer is '10'.
