Read the given statements and select the correct options.Statement 1: ...
Statement 1: Each sperm of moss has two flagella.
Statement 2: Water is essential for fertilization in mosses.
Explanation:
The correct answer is option 'B' - Both statements 1 and 2 are correct but statement 2 is not the correct explanation of statement 1.
1. Importance of Water in Moss Fertilization:
- Mosses are non-vascular plants that reproduce through the process of fertilization.
- In order for fertilization to occur in mosses, water is essential.
- Mosses require a moist environment for the male and female gametes to come in contact with each other.
- The presence of water is necessary for the sperm to swim from the male reproductive structure (antheridium) to the female reproductive structure (archegonium) where fertilization takes place.
- Water acts as a medium for the movement of sperm and facilitates the union of gametes, leading to fertilization.
2. Flagella in Moss Sperm:
- Mosses are unique in that they have swimming sperm, unlike most other plants where fertilization occurs through passive pollen transfer.
- The sperm of mosses are flagellated, meaning they possess whip-like structures called flagella that enable them to move in a liquid environment.
- Each sperm of moss possesses two flagella, which provide the necessary motility for the sperm to swim through the water to reach the egg for fertilization.
- The flagella help the sperm to navigate in the water towards the female reproductive structure and increase the chances of successful fertilization.
Explanation of the Correct Answer (Option B):
Both statements 1 and 2 are correct, as moss sperm do have two flagella and water is indeed essential for fertilization in mosses. However, statement 2 is not the correct explanation of statement 1.
Statement 1 simply states a fact about moss sperm having two flagella, whereas statement 2 provides the reason behind the requirement of water for fertilization in mosses. The two statements are related but not interdependent on each other.

Sperm of mosses is biflagellated. i.e. it has two flages that aid in propulsion. Since sperm must swim to the archegonium fertilization cannot occur without water.
