Answer:
The correct answer is 'Stem and root apices'
Explanation:
Promeristem is the portion of the primary shoot apical meristem which contains actively dividing, undifferentiated, isodiametric thin-walled cells.
The shoot apical meristem (SAM) consists of three distinct meristematic zones called the histogens.
These histogens are present at the growing tips of a stem or a root.
These tips consist of three histogens and each of these histogens gives rise to tissues which are different from one another- dermatogen, periblem, plerome (principle tissues)
The dermatogen or the outer layer gives rise to the epidermis, periblem or middle layer gives rise to the cortex as well as the epidermis, plerome or the inner layer gives rise to vascular tissues.
Hope this answer helps you out.
