Pick out the wrong statement

Options

A. Double fertilization is unique to gymnosperms and monocotyledons
B. Sequoia, a gymnosperm is one of the tallest trees
C. Phaeophyceae members possess chlorophylls a, c, carotenoids and xanthophylls
D. Moss is a gametophyte which consists of two stages, namely protonema stage and leafy stage.

Answer

To solve the question of identifying the wrong statement, we will analyze each provided statement step by step.

### Step 1: Analyze the first statement
- **Statement**: "Double fertilization is unique to gymnosperms and monocotyledons."
- **Analysis**: This statement is incorrect. Double fertilization is a process that occurs in angiosperms (flowering plants), not gymnosperms. Gymnosperms do not undergo double fertilization. Therefore, this statement is the wrong one.

### Step 2: Analyze the second statement
- **Statement**: "Skewa, a gymnosperm, is one of the talastry."
- **Analysis**: This statement is correct. Skewa (or Sequoia) is indeed a gymnosperm and is classified within the group of conifers, which are part of the gymnosperms.

### Step 3: Analyze the third statement
- **Statement**: "P-O-5-C members possess chlorophyll A, C, chitonoids, and genthophils."
- **Analysis**: This statement is also correct. Members of the group Phaeophyceae (brown algae) do possess chlorophyll A and C, as well as other pigments like fucoxanthin (which may be referred to as chitonoids in some contexts).

### Step 4: Analyze the fourth statement
- **Statement**: "Moss is a gametophyte which consists of two states namely protonema stage and leafy stage."
- **Analysis**: This statement is correct. Mosses do have a gametophyte stage that includes the protonema stage (the initial stage of growth) and the leafy stage (the mature stage).

### Conclusion
After analyzing all the statements, we conclude that the wrong statement is:
- "Double fertilization is unique to gymnosperms and monocotyledons."

### Final Answer
The correct option is that the wrong statement is: "Double fertilization is unique to gymnosperms and monocotyledons."
