Which of the following is not a characteristic of leaf?

Options

A. Shows determinate growth
B. Originate endogeneously as a lateral outgrowth
C. Originate from shoot meristem
D. Does not possess a regular growing point

Explanation

To determine which of the following is not a characteristic of a leaf, we will analyze each option step by step.

### Step 1: Analyze Option 1
- **Statement**: Leaves show determinate growth.
- **Explanation**: Leaves have a limited growth pattern, meaning they grow to a certain size and then stop. This is known as determinate growth.
- **Conclusion**: This statement is correct.

### Step 2: Analyze Option 2
- **Statement**: They originate endogenously like a lateral outgrowth.
- **Explanation**: Leaves do not originate endogenously; they originate exogenously from the shoot apex. Endogenous growth refers to growth from within, while leaves are formed from the outer layers of the plant.
- **Conclusion**: This statement is incorrect.

### Step 3: Analyze Option 3
- **Statement**: They develop from the leaf primordium which is part of the growing apex.
- **Explanation**: Leaves do indeed develop from leaf primordia, which are formed at the shoot apex. This is a correct characteristic of leaves.
- **Conclusion**: This statement is correct.

### Step 4: Analyze Option 4
- **Statement**: They don't possess any regular growing point.
- **Explanation**: Leaves do not have an apical bud or a regular growing point like stems do. They are lateral appendages that grow from nodes on the stem.
- **Conclusion**: This statement is correct.

### Final Conclusion
After analyzing all the options, we find that the statement that is not a characteristic of a leaf is **Option 2**: "They originate endogenously like a lateral outgrowth."
