Which of the following plants are similar in requirement of water for fertilisation ?

Options

A. Bryophyta
B. Pteridophyta
C. Angiosperm
D. (1) and (2) both

Answer

To determine which plants have similar requirements for water during fertilization, we need to analyze the reproductive processes of different plant groups. Here’s a step-by-step solution:

### Step 1: Understand the Requirement of Water in Plant Fertilization
- In plants, fertilization often requires the movement of male gametes (sperm) to the female gametes (egg). In many plant groups, this movement is facilitated by water.

### Step 2: Identify Plant Groups
- The main groups of plants to consider here are:
- Bryophytes (e.g., mosses)
- Pteridophytes (e.g., ferns)
- Angiosperms (flowering plants)

### Step 3: Analyze Bryophytes
- Bryophytes are known as the amphibians of the plant kingdom. They require water for the sperm to swim to the egg for fertilization. Therefore, they have a significant dependence on water for reproductive success.

### Step 4: Analyze Pteridophytes
- Pteridophytes also require water for fertilization. Similar to bryophytes, the sperm must swim through water to reach the egg. This means they share the same requirement for water during fertilization.

### Step 5: Analyze Angiosperms
- Angiosperms, on the other hand, often do not require water for fertilization in the same way. They rely on pollination, which can occur through biotic (animals, insects) or abiotic (wind, water) agents. Thus, they are not similar to bryophytes and pteridophytes in this aspect.

### Step 6: Conclusion
- Based on the analysis, both bryophytes and pteridophytes require water for fertilization, while angiosperms do not have the same requirement. Therefore, the correct answer to the question is that options 1 (Bryophytes) and 2 (Pteridophytes) are similar in their requirement for water for fertilization.

### Final Answer:
- The correct option is 4, which states that both 1 and 2 are correct.
