Answer

To solve the question "Multiciliate male gametes are found in:", we can follow these steps:

### Step 1: Understand the Types of Male Gametes
- Male gametes can vary in structure and form among different plant species. In some plants, male gametes are motile and possess flagella or cilia.

### Step 2: Identify Key Characteristics
- The term "multiciliate" indicates that the male gametes have multiple cilia or flagella. This is a specific characteristic that can help us narrow down the options.

### Step 3: Review Examples of Plants
- The transcript mentions several plants: Pinus, Cycus, Natum, and Mango. We need to analyze these plants to determine which one has multiciliate male gametes.

### Step 4: Analyze Each Plant
- **Pinus**: This is a gymnosperm, and its male gametes (pollen) are not multiciliate.
- **Cycus**: This is also a gymnosperm and is known for having multiciliate male gametes. The male gametes of Cycus are described as multi-flagellate, meaning they have multiple flagella.
- **Natum**: Information about the male gametes is not specified in the transcript, but it is not commonly known for multiciliate gametes.
- **Mango**: This is an angiosperm, and its male gametes (pollen) do not have multiple cilia.

### Step 5: Conclusion
- Based on the analysis, the only plant mentioned that has multiciliate male gametes is **Cycus**. Therefore, the correct answer is Cycus.

### Final Answer
- Multiciliate male gametes are found in **Cycus**.
