Formation of cork cambium is___(i) ___ while formation of secondary cortex and cork is ____(ii) ___

Options

A. (i) Differentiation (it) Dedifferentiation
B. (i) Dedifferentiation (ii)Redifferentiation
C. (i) Redifferentiation (ii) Dedifferentiation
D. (I)Dedifferentiation(ii) Redifferentiation

Answer

To solve the question regarding the formation of cork cambium and the secondary cortex and cork, we can break it down into two parts as follows:

### Step-by-Step Solution:

1. **Understanding Cork Cambium Formation:**
- Cork cambium is a type of lateral meristematic tissue that is responsible for producing cork (the outer protective layer of the plant).
- The formation of cork cambium occurs through a process called **de-differentiation**. This means that certain cells that were previously specialized lose their specific functions and revert to a simpler, more generalized state. This allows them to divide and form new tissues.

2. **Understanding the Formation of Secondary Cortex and Cork:**
- After the formation of cork cambium, it undergoes further processes where it produces secondary cortex and cork.
- The formation of secondary cortex and cork involves a process known as **re-differentiation**. In this case, the cells that were once de-differentiated now specialize again to form more complex structures, such as the secondary cortex and cork.

### Final Answer:
- Formation of cork cambium is **(i) de-differentiation** while formation of secondary cortex and cork is **(ii) re-differentiation**.
