Select the incorrect statement .

Options

A. Growth, at a cellular level, is principally a consequence of increase in the amount of protoplasm
B. In maize, the growth in root apical meristem growth as an increase in the size of the cell.
C. The growth of a pollen tube is measured in terms of its length .
D. An increase in surface area denotes the growth in a dorsiventral leaf.

Answer

To solve the question, we need to analyze each statement provided and determine which one is incorrect. Let's go through the statements step by step.

### Step 1: Analyze the First Statement
**Statement:** Growth at a cellular level is principally a consequence of increase in the amount of protoplasm.

**Analysis:** This statement is correct. Growth at the cellular level indeed involves an increase in protoplasm, which includes the cytoplasm and organelles. As cells grow, the amount of protoplasm increases, leading to an increase in cell size.

### Step 2: Analyze the Second Statement
**Statement:** In maize, the growth in root apical meristem growth is an increase in the size of the cell.

**Analysis:** This statement is incorrect. The root apical meristem is responsible for producing new cells, and growth occurs primarily due to an increase in the number of cells rather than just an increase in the size of existing cells. Therefore, this statement does not accurately describe the function of the apical meristem.

### Step 3: Analyze the Third Statement
**Statement:** The growth of pollen tube is measured in terms of its length.

**Analysis:** This statement is correct. The growth of a pollen tube is indeed measured by its length as it elongates during the fertilization process.

### Step 4: Analyze the Fourth Statement
**Statement:** An increase in surface area denotes the growth in dwarf sea ventral leaf.

**Analysis:** This statement is also correct. An increase in surface area can indicate growth in leaves, including dwarf varieties, as it allows for more photosynthesis and better resource acquisition.

### Conclusion
After analyzing all statements, we find that the **incorrect statement** is the **second statement** regarding the growth in the root apical meristem.

### Final Answer
The incorrect statement is: **In maize, the growth in root apical meristem growth is an increase in the size of the cell.**
