origin of vegatative branch is

Options

A. schizogenous
B. endogenous
C. exogenous
D. internal form intercalary meristem

Answer

To answer the question about the origin of vegetative branches, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Vegetative Branches**:
- Vegetative branches are parts of the plant that develop from axillary buds. These buds are located in the leaf axils (the angle between the leaf and the stem).

2. **Identify the Origin of Axillary Buds**:
- Axillary buds arise from the cortex of the plant. The cortex is a layer of tissue found beneath the epidermis and above the vascular tissue.

3. **Determine the Type of Origin**:
- The origin of vegetative branches can be classified into three types:
- **Exogenous**: Originating from outside tissues.
- **Endogenous**: Originating from internal tissues.
- **Shiogenous**: Related to the formation of intracellular spaces due to cell wall separation.

4. **Analyze the Options**:
- **Shiogenous**: Incorrect, as this term refers to intracellular spaces and is not related to vegetative branches.
- **Endogenous**: Incorrect, as this refers to structures that arise from the pericycle, which is associated with roots, not branches.
- **Exogenous**: Correct, as axillary buds (from which vegetative branches arise) develop from the cortex, making them exogenous.
- **Internal form Intercalary meristem**: Incorrect, as this type of meristem is involved in the elongation of stems and is not related to the origin of branches.

5. **Conclusion**:
- Based on the analysis, the correct answer is that the origin of vegetative branches is **Exogenous**.

### Final Answer:
The origin of vegetative branches is **Exogenous**.
