Maize plant possesses which of the following morphological features ?
(i) Trimerous flowers
(ii) Leaves with parallel venation
(iii) Solid branched stem
(iv) isobilateral leaves

Options

A. i, ii
B. ii, iii, iv
C. i , ii,iv
D. ii , iv

Answer

To determine the morphological features of the maize plant, we will analyze each of the given options one by one.

### Step-by-Step Solution:

1. **Trimerous Flowers**:
- Trimerous flowers are characterized by having floral parts in multiples of three (e.g., three petals, three sepals).
- Maize flowers are indeed trimerous, as they belong to the family Poaceae (grasses), which typically exhibit this feature.
- **Conclusion**: This feature is present in maize.

2. **Leaves with Parallel Venation**:
- Parallel venation refers to the arrangement of veins in leaves where they run parallel to each other.
- Maize, being a monocot plant, has leaves that exhibit parallel venation.
- **Conclusion**: This feature is also present in maize.

3. **Solid Branched Stem**:
- Maize has a stem that is typically solid and unbranched. The stems of monocots like maize are usually not branched but can be strong and erect.
- However, the term "solid branched stem" is misleading since maize does not have a branched stem in the traditional sense.
- **Conclusion**: This feature is NOT present in maize.

4. **Isobilateral Leaves**:
- Isobilateral leaves have a symmetrical structure on both sides, which is common in monocots.
- In maize, the leaves are isobilateral, meaning the stomata are present on both sides of the leaves.
- **Conclusion**: This feature is present in maize.

### Final Evaluation:
From the analysis, the features that maize possesses are:
- (i) Trimerous flowers: Yes
- (ii) Leaves with parallel venation: Yes
- (iii) Solid branched stem: No
- (iv) Isobilateral leaves: Yes

Thus, the correct morphological features of the maize plant are options (i), (ii), and (iv).

### Answer:
The maize plant possesses the following morphological features:
(i) Trimerous flowers, (ii) Leaves with parallel venation, and (iv) Isobilateral leaves.
