Which one is a wrong statement?

Options

A. (a) Archegonia are found in Bryophyta, Pteridophyta and Gymnosperms
B. (b) Mucor has biflagellate zoospores
C. (c) Haploid endosperm is typical feature of gymnosperms
D. (d) Brown algae have chlorophyll a and c,and fucoxanthin

Answer

To determine which statement is incorrect, we will analyze each option provided in the question step by step.

### Step 1: Analyze Statement A
- **Statement A**: "Archegonia are found in Bryophyta, Pteridophyta, and Gymnosperms."
- **Analysis**: This statement is true. Archegonia are indeed the female reproductive structures found in all three groups: Bryophyta (mosses), Pteridophyta (ferns), and Gymnosperms (conifers).

### Step 2: Analyze Statement B
- **Statement B**: "Mucor has biflagellate zoospores."
- **Analysis**: This statement is false. Mucor, which belongs to the kingdom Fungi and the division Zygomycetes, produces non-motile, non-flagellated zygospores. Therefore, this statement is incorrect.

### Step 3: Analyze Statement C
- **Statement C**: "Haploid endosperm is a typical feature of gymnosperms."
- **Analysis**: This statement is true. In gymnosperms, the endosperm is haploid and serves as a nutrient source for the developing embryo, which is a typical characteristic of these plants.

### Step 4: Analyze Statement D
- **Statement D**: "Brown algae have chlorophyll A, C, and fucoxanthin."
- **Analysis**: This statement is also true. Brown algae contain chlorophyll A and C, along with the pigment fucoxanthin, which gives them their characteristic brown color.

### Conclusion
After analyzing all the statements, we find that the incorrect statement is **Statement B**: "Mucor has biflagellate zoospores."

### Final Answer
- The wrong statement is **B**.
