Select an incorrect statement

Options

A. Stems of Euphorbia contain chlorophyll
B. In mint and jasmine the lateral branches originate from the basal and underground portion of the main stem, grow horizontally beneath the soil and then come out obliquely upward giving rise to leafy shoots.
C. A lateral branch with each node bearing a rosette of leaves and a tuft of roots is found in aquatic plants Eichhornia.
D. Underground stems of some plants such as strawberry spread to new niches

Answer

To solve the question "Select an incorrect statement," we will analyze each of the provided statements one by one to determine which one is incorrect.

### Step-by-Step Solution:

1. **Statement A:** "The stems of Euphorbia contain chlorophyll."
- **Analysis:** Euphorbia plants, which are often found in arid regions, have modified stems that perform photosynthesis due to the presence of chlorophyll. Since Euphorbia lacks leaves to minimize water loss, its stems are flattened and green, allowing them to carry out photosynthesis effectively.
- **Conclusion:** This statement is **correct**.

2. **Statement B:** "In the mint and jasmine, the lateral branches originate from the basal and underground portion of the main stem, grow horizontally beneath the soil, and then come obliquely upward giving rise to the leafy shoot."
- **Analysis:** This statement describes a growth pattern that is not characteristic of mint and jasmine. Instead, this growth pattern is typical of plants like banana. In mint and jasmine, lateral branches do not originate from the underground portion of the main stem in this manner.
- **Conclusion:** This statement is **incorrect**.

3. **Statement C:** "A lateral branch with each node bearing a rosette of leaves and a tuft of roots is found in the aquatic plant Echornia."
- **Analysis:** This statement accurately describes the growth form of Echornia, where each node indeed bears a rosette of leaves and roots.
- **Conclusion:** This statement is **correct**.

4. **Statement D:** "The underground stem of some plants such as strawberry spreads to the new niche."
- **Analysis:** This statement is also true. Strawberry plants utilize underground stems (runners) to spread and establish new plants in different areas.
- **Conclusion:** This statement is **correct**.

### Final Conclusion:
The incorrect statement is **Statement B**.
