Solution
The correct option is A Cortex
- The shoot apical meristem (SAM) of a plant form three distinct meristematic zones called the histogens (histogen theory).
- These histogens are present at the growing shoot tip or root tip.
These tips consist of three histogens based on the type of cells they form.- Each of these histogens gives rise to tissues which are different from one another- dermatogen, periblem, plerome (principle tissues)
1) The dermatogen or the outer layer gives rise to the epidermis.2) The periblem or middle layer gives rise to the cortex and the endodermis (compact living cells with hydrophobic substances) which is the innermost layer of the cortex.3)The plerome or the inner layer gives rise to vascular tissues- So, the correct answer is 'Cortex'
