Which one is wrong statement ?

Options

A. Haploid endosperm is typical feature of Gymnosperms.
B. Brown algae have chlorophyll a and c and fucoxanthin .
C. Archegonia are found in Bryophyll Pteridphyte and Gymnosperms .
D. Mucor has biflagellate zoospore

Answer

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

### Step 1: Analyze the first statement
**Statement:** Haploid endosperm is the typical feature of gymnosperms.

**Analysis:**
- The endosperm in gymnosperms is typically haploid because it develops from the haploid megaspore.
- In contrast, angiosperms have a triploid endosperm formed after fertilization.
- Therefore, this statement is **correct**.

### Step 2: Analyze the second statement
**Statement:** Brown algae have chlorophyll-A and C and phytoxanthine.

**Analysis:**
- Brown algae contain chlorophyll A and C, as well as the pigment fucoxanthin, which gives them their characteristic brown color.
- The term "phytoxanthine" seems to be a misnomer; the correct term is fucoxanthin.
- However, the presence of chlorophyll A and C is accurate.
- Therefore, this statement is **correct** despite the slight inaccuracy in terminology.

### Step 3: Analyze the third statement
**Statement:** Archegonia are found in bryophytes, tracheophytes, and gymnosperms.

**Analysis:**
- Archegonia are indeed the female reproductive structures found in bryophytes (mosses and liverworts), tracheophytes (ferns), and gymnosperms (like conifers).
- Therefore, this statement is **correct**.

### Step 4: Analyze the fourth statement
**Statement:** Mucor has biflagellate zoospores.

**Analysis:**
- Mucor is a genus of fungi belonging to the Zygomycetes.
- Zygomycetes produce non-motile and non-flagellated gametes, meaning they do not have biflagellate zoospores.
- Therefore, this statement is **incorrect**.

### Conclusion
After analyzing all the statements, the incorrect statement is the fourth one: "Mucor has biflagellate zoospores."
