Pick out the Wrong statement:

Options

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

Answer

To solve the question of identifying the wrong statement, we will analyze each of the four statements provided:

### Step 1: Analyze Statement 1
- **Statement:** "Double Fertilization is unique to Gymnosperms and Monocotylidins."
- **Analysis:** Double fertilization is a process where one male gamete fertilizes the egg cell to form a zygote, and the other male gamete fuses with the central cell to form the endosperm. This process is characteristic of Angiosperms (flowering plants), not Gymnosperms. Therefore, this statement is incorrect.

### Step 2: Analyze Statement 2
- **Statement:** "Sequoia is one of the tallest trees."
- **Analysis:** This statement is true. Sequoia, a type of gymnosperm, is indeed one of the tallest trees in the world.

### Step 3: Analyze Statement 3
- **Statement:** "Pheophyceae, a member possesses chlorophyll A, C, carotenoids and xanthophylls."
- **Analysis:** This statement is correct. Pheophyceae refers to brown algae, which contain chlorophyll A, chlorophyll C, carotenoids, and xanthophylls.

### Step 4: Analyze Statement 4
- **Statement:** "Moss is gametophyte, which consists of two stages, namely protonema stage and leafy stage."
- **Analysis:** This statement is also correct. Mosses are bryophytes, and their life cycle includes the protonema stage and the leafy stage, which are both part of the gametophyte generation.

### Conclusion
After analyzing all four statements, we find that:
- **The wrong statement is Statement 1.** Double fertilization is not unique to Gymnosperms and Monocotylidins; it is a feature of Angiosperms.

### Final Answer
The wrong statement is: **"Double Fertilization is unique to Gymnosperms and Monocotylidins."**
