Analyse the following statements about class – Ascomycetes.
I. Mycelium is branched and septate.
II. The asexual spores are conidia, produced on the special mycelium called conidiophores.
III. Sexual spores are called ascospores, which are produced in sac- like asci.
Which of the statements given above are correct?

Options

A. I and II
B. I and III
C. II and III
D. All of these

Answer

To analyze the statements about the class Ascomycetes, let's break down each statement step by step:

### Step 1: Analyze Statement I
**Statement I:** Mycelium is branched and septate.

- **Explanation:** In Ascomycetes, the mycelium is indeed composed of branched structures known as hyphae. These hyphae are divided by septa (cross-walls), making the mycelium septate. Therefore, this statement is **correct**.

### Step 2: Analyze Statement II
**Statement II:** The asexual spores are conidia, produced on the special mycelium called conidiophores.

- **Explanation:** Ascomycetes produce asexual spores known as conidia. These conidia are formed on specialized structures called conidiophores. This means that this statement is also **correct**.

### Step 3: Analyze Statement III
**Statement III:** Sexual spores are called ascospores, which are produced in sac-like asci.

- **Explanation:** In Ascomycetes, the sexual spores are indeed referred to as ascospores. These ascospores are produced within sac-like structures called asci. Therefore, this statement is **correct** as well.

### Conclusion
All three statements about Ascomycetes are correct. Thus, the answer to the question is that all statements (I, II, and III) are correct.

### Final Answer
**All statements (I, II, and III) are correct.**
