Pick out wrong statement

Options

A. Double fertilisation is unique to gymnosperms and monocotyledons
B. Sequoia, a gymnosperm, is one of the tallest trees
C. Phaeophyceae members possess chlorophyll 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 "Pick out the wrong statement," we will analyze each statement provided in the video transcript step by step.

### Step 1: Analyze Statement 1
- **Statement**: Double fertilization is unique to gymnosperms and monocotyledons.
- **Evaluation**: This statement is incorrect. Double fertilization is a process that occurs only in angiosperms (flowering plants), which include both monocotyledons (monocots) and dicotyledons (dicots). Gymnosperms do not undergo double fertilization.

### Step 2: Analyze Statement 2
- **Statement**: Sequoia, a gymnosperm, is one of the tallest trees.
- **Evaluation**: This statement is correct. Sequoia trees are indeed among the tallest trees in the world and are classified as gymnosperms.

### Step 3: Analyze Statement 3
- **Statement**: Pheophyceae members possess chlorophyll A, C, carotenoids, and xanthophyll.
- **Evaluation**: This statement is correct. Pheophyceae, commonly known as brown algae, do contain chlorophyll A, chlorophyll C, carotenoids, and xanthophyll.

### Step 4: Analyze Statement 4
- **Statement**: Moss is a gametophyte that consists of two stages only.
- **Evaluation**: This statement is misleading. While moss is primarily a gametophyte, it has two main stages: the protonema stage and the leafy stage. However, it is important to note that there are more complexities in the life cycle of mosses.

### Conclusion
After evaluating all the statements, we find that:
- **Wrong Statement**: Statement 1 is incorrect because double fertilization is not unique to gymnosperms and monocots; it is unique to angiosperms.

### Final Answer
The wrong statement is **Statement 1**.
