Which statement is incorrect ?
(a) Reduction division occurs inside fruiting bodies leading to formation of spores
(b) Conidia are produced endogenously
(c) Formation of ascospores occurs inside ascus
(d) Rust diseases in wheat caused by Puccinia

Options

A. b
B. c
C. d
D. none

Answer

To determine which statement is incorrect among the given options, let's analyze each one step by step:

1. **Option (a): Reduction division occurs inside fruiting bodies leading to formation of spores.**
- Reduction division, or meiosis, occurs in the fruiting bodies of fungi, leading to the formation of haploid spores. This statement is correct because meiosis is essential for spore formation in many fungi.

2. **Option (b): Conidia are produced endogenously.**
- Conidia are a type of asexual spore produced by fungi. They are formed on specialized structures called conidiophores, and they are indeed produced endogenously (inside the structure). This statement is also correct.

3. **Option (c): Formation of ascospores occurs inside ascus.**
- Ascospores are sexual spores produced by fungi in a sac-like structure called an ascus. This statement is correct as well, as it accurately describes the process of ascospores formation.

4. **Option (d): Rust diseases in wheat caused by Puccinia.**
- Rust diseases in wheat are indeed caused by fungi of the genus Puccinia, such as Puccinia triticina, which causes leaf rust. This statement is correct.

After analyzing all the options, we find that all the statements (a, b, c, and d) are correct. Therefore, there is no incorrect statement among the options provided.

**Final Answer: None of the statements are incorrect.**
