In which of the following are the reproductive organs hidden?

Options

A. Cryptogamae
B. Phanerogamae
C. Gymnosperms
D. Angiosperms

Answer

To solve the question "In which of the following are the reproductive organs hidden?", we need to understand the classification of plants based on their reproductive structures. Here’s a step-by-step breakdown:

### Step 1: Understand the Terms
- **Cryptogams**: This term comes from the Greek word "cryptos" meaning hidden and "gammy" meaning marriage. Cryptogams are plants that have hidden reproductive organs.
- **Phanerogams**: This term comes from the Greek word "phaneros" meaning visible and "gammy" meaning marriage. Phanerogams are plants that have visible reproductive organs.

### Step 2: Classify the Plant Kingdom
- The plant kingdom is divided into two main categories:
1. **Cryptogams**: Includes three divisions:
- **Thalophyta**: Simple plants like algae.
- **Bryophyta**: Non-vascular plants like mosses.
- **Pteridophyta**: Vascular plants like ferns.
2. **Phanerogams**: Includes two divisions:
- **Gymnosperms**: Seed-producing plants with exposed seeds.
- **Angiosperms**: Flowering plants with seeds enclosed in fruits.

### Step 3: Identify the Correct Answer
- Since the question asks for the group where reproductive organs are hidden, we focus on **Cryptogams**.
- In contrast, Phanerogams (Gymnosperms and Angiosperms) have visible reproductive organs.

### Conclusion
The correct answer to the question is **Cryptogams**, as they are the group of plants where the reproductive organs are hidden.
