Go through the following statements
(i) In geometr,ic growth, following mitotic cell division, only one daughter cell con- tinues to divide while the other differen- tiates and mature.
(ii) The ability of plants to follow different pathways in response to environment or phases of life to to.rm different kinds of structures, is called plasticity.
(iii) The mathematical expression for arith- metic growth is `Lt = L_0 + rt` while for geo- metric growth, it is `W_1=W_0=W_(0)e^(rt)`
(iv) The form of growth wherein new cells are always being added to the plant body by the activity of the meristem, is called the open form of growth.
Which of these are correct .

Options

A. (iii) & (iv)
B. (ii), (iii) & (iv)
C. (ii) & (iv)
D. All are correct

Answer

To determine which of the statements are correct, let's analyze each statement one by one:

### Step 1: Analyze Statement (i)
**Statement:** In geometric growth, following mitotic cell division, only one daughter cell continues to divide while the other differentiates and matures.

**Analysis:** This statement is incorrect. In geometric growth, both daughter cells continue to divide. It is in arithmetic growth where one daughter cell continues to divide while the other differentiates.

### Step 2: Analyze Statement (ii)
**Statement:** The ability of plants to follow different pathways in response to the environment or phases of life to form different kinds of structures is called plasticity.

**Analysis:** This statement is correct. Plasticity refers to the ability of plants to adapt their growth and development in response to environmental conditions or different life stages.

### Step 3: Analyze Statement (iii)
**Statement:** The mathematical expression for arithmetic growth is \( L_t = L_0 + rt \) while for geometric growth, it is \( W_1 = W_0 e^{rt} \).

**Analysis:** This statement is correct. The formula for arithmetic growth is indeed \( L_t = L_0 + rt \) and for geometric growth, it is \( W_1 = W_0 e^{rt} \).

### Step 4: Analyze Statement (iv)
**Statement:** The form of growth wherein new cells are always being added to the plant body by the activity of the meristem is called the open form of growth.

**Analysis:** This statement is correct. The open form of growth refers to continuous growth where new cells are produced by the meristematic tissues.

### Conclusion:
Based on the analysis:
- Statement (i) is incorrect.
- Statements (ii), (iii), and (iv) are correct.

Thus, the correct statements are (ii), (iii), and (iv).

### Final Answer:
The correct statements are (ii), (iii), and (iv).
