Perianth modifies into Iodicules in the members which also contain

Options

A. Spikelet inflorescence
B. Monocarpellary ovary
C. Tetramerous flower
D. Both (1) and (2)

Answer

To solve the question regarding the modification of perianth into lodicules in certain plant members, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Perianth and Lodicules**:
- The perianth is the non-reproductive part of a flower, which includes the petals and sepals. In some plants, particularly in the family Poaceae (grasses), the perianth can modify into small structures known as lodicules.

2. **Identifying the Family**:
- Lodicules are specifically found in the family Poaceae. This family is characterized by its unique flower structure and inflorescence type.

3. **Inflorescence Type**:
- In Poaceae, the inflorescence is often in the form of spikelets. A spikelet is the smallest unit of inflorescence in grasses, consisting of one or more florets.

4. **Ovary Structure**:
- The flowers in the Poaceae family typically have a monocarpillary ovary, which means that there is a single carpel (the female reproductive part) in the flower. This ovary usually contains a single ovule, which is attached to the ovary wall at the base (basal placentation).

5. **Analyzing the Options**:
- The question provides several options:
- (1) Spiculate inflorescence
- (2) Monocarpillary ovary
- (3) Tetramerous flower
- (4) Both (1) and (2)
- Since we established that the perianth modifies into lodicules in members of the Poaceae family, which have spikelet inflorescence and a monocarpillary ovary, the correct answer is option (4) - both (1) and (2).

### Final Answer:
The correct answer is **(4) Both (1) and (2)**.
