In two plants A and B the first plant shows horizontally growing underground stem and the second plant shows vertically growing underground stem and both of them belong to the same family. A and B plants respectively are

Options

A. Musa, Colocasia
B. Zingiber, Amorphophallus
C. Allium, Gloriosa
D. Gloriosa, Colchicum

Answer

To solve the question regarding the two plants A and B, we need to identify their characteristics based on the description provided. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Characteristics of the Plants
- Plant A has a horizontally growing underground stem.
- Plant B has a vertically growing underground stem.
- Both plants belong to the same family.

### Step 2: Identify Possible Families
We need to consider families of plants that might contain species with both horizontal and vertical underground stems. The families mentioned in the video are:
1. Musaceae (Musa)
2. Araceae (Colocasia, Amorphophallus)
3. Zingiberaceae (Zingiber)
4. Amaryllidaceae (Allium)
5. Colchicaceae (Gloriosa, Colchicum)

### Step 3: Analyze the Plants in Each Family
- **Musaceae**: Contains Musa, which typically has a vertical stem.
- **Araceae**: Contains Colocasia (which has a horizontal stem) and Amorphophallus (which has a vertical stem).
- **Zingiberaceae**: Contains Zingiber, which has a vertical stem.
- **Amaryllidaceae**: Contains Allium, which has a vertical stem.
- **Colchicaceae**: Contains Gloriosa (which has a vertical stem) and Colchicum (which has a horizontal stem).

### Step 4: Match the Plants with Their Characteristics
From the analysis:
- **Colocasia** (horizontal stem) and **Amorphophallus** (vertical stem) belong to the same family (Araceae).
- **Colchicum** (horizontal stem) and **Gloriosa** (vertical stem) belong to the same family (Colchicaceae).

### Step 5: Conclusion
Since both pairs belong to the same family, we can conclude that:
- Plant A (horizontal stem) is **Colchicum**.
- Plant B (vertical stem) is **Gloriosa**.

Thus, the answer is:
**A and B plants respectively are Colchicum and Gloriosa.**
