In Puccinia karyogamy & meiosis takes place inside :–

Options

A. Basidiospores
B. Aceiospores
C. Telutospores
D. Uredospores

Answer

To answer the question "In Puccinia, karyogamy & meiosis takes place inside:–", we can follow these steps:

### Step 1: Understand the Life Cycle of Puccinia
Puccinia is a genus of fungi known as rust fungi, which are obligate plant pathogens. Their life cycle includes several stages, including the production of different types of spores.

**Hint:** Familiarize yourself with the life cycle of rust fungi, particularly the stages where karyogamy and meiosis occur.

### Step 2: Identify Key Processes
Karyogamy is the fusion of two nuclei, and meiosis is the process of cell division that reduces the chromosome number by half, resulting in the formation of spores.

**Hint:** Recall the definitions of karyogamy and meiosis and their significance in the fungal life cycle.

### Step 3: Examine the Options
The question provides several options regarding where karyogamy and meiosis occur in Puccinia:
1. Basidiospores
2. Achaeospores
3. Teliospores
4. Urediospores

**Hint:** Consider the characteristics of each type of spore and their role in the life cycle of Puccinia.

### Step 4: Analyze Each Option
- **Basidiospores:** These are produced in Basidiomycetes and are not relevant to Puccinia.
- **Achaeospores:** These spores are associated with rust fungi but do not represent the stage where karyogamy and meiosis occur.
- **Teliospores:** This is the correct answer. Teliospores are the thick-walled spores produced by Puccinia where karyogamy occurs, followed by meiosis.
- **Urediospores:** These are thin-walled spores produced during the asexual stage and do not undergo karyogamy or meiosis.

**Hint:** Focus on the specific characteristics of teliospores in the context of Puccinia's life cycle.

### Step 5: Conclude the Answer
Based on the analysis, karyogamy and meiosis in Puccinia take place inside **teliospores**.

**Final Answer:** The correct answer is **teliospores**.
