Monocot plants are characterized by the presence of how many of the following characters?
Scutellum, Reticulate venation, Fibrous roots, stilt roots, Pulvinous leaf base, isobilateral leaves

Options

A. two
B. three
C. four
D. all of these

Answer

To determine how many of the listed characters are found in monocot plants, we will analyze each character one by one:

1. **Scutellum**:
- The scutellum is a specialized structure found in the seeds of monocots, such as maize and wheat. It serves to absorb nutrients during seed germination.
- **Conclusion**: Present in monocots.

2. **Reticulate venation**:
- Reticulate venation refers to a pattern where veins form a net-like structure. This type of venation is typically found in dicot plants. Monocots, on the other hand, usually exhibit parallel venation.
- **Conclusion**: Not present in monocots.

3. **Fibrous roots**:
- Monocots are characterized by having fibrous root systems, which consist of many thin roots that spread out from the base of the plant. This is in contrast to dicots, which often have a taproot system.
- **Conclusion**: Present in monocots.

4. **Stilt roots**:
- Stilt roots are specialized roots that provide support and are commonly found in some dicot plants, such as mangroves. They help the plant to stabilize in soft, wet soil.
- **Conclusion**: Not present in monocots.

5. **Pulvinous leaf base**:
- A pulvinus is a swollen structure at the base of a leaf, which is typically found in dicot plants. It serves as a food reserve and aids in leaf movement.
- **Conclusion**: Not present in monocots.

6. **Isobilateral leaves**:
- Isobilateral leaves are characterized by having similar structures on both sides of the leaf. This type of leaf arrangement is commonly found in monocot plants, particularly grasses.
- **Conclusion**: Present in monocots.

Now, let's summarize the findings:
- Characters present in monocots: Scutellum, Fibrous roots, Isobilateral leaves.
- Characters not present in monocots: Reticulate venation, Stilt roots, Pulvinous leaf base.

**Final Count**: There are **3 characters** that are present in monocot plants.
