In Ginkgoales the male gametes are :-

Options

A. Motile
B. Non-motile
C. Amoeboid
D. Absent

Answer

To answer the question regarding the nature of male gametes in Ginkgoales, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Group**: Recognize that Ginkgoales is a group within gymnosperms. Gymnosperms are seed-producing plants that do not form flowers or fruits.

2. **Understand Heterospory**: Gymnosperms, including Ginkgo, are heterosporous, meaning they produce two types of spores: microspores and megaspores.

3. **Identify Sporophylls**: In Ginkgo, the structures that bear spores are called sporophylls. There are two types of sporophylls: microsporophylls (which produce microspores) and megasporophylls (which produce megaspores).

4. **Microspores Development**: Microsporophylls contain microsporangia, which produce microspores. These microspores develop into male gametes.

5. **Nature of Male Gametes**: In Ginkgo, the male gametes (which develop from microspores) are motile. This means they are capable of movement, typically through the use of flagella.

6. **Conclusion**: Therefore, the correct answer to the question is that the male gametes in Ginkgoales are motile.

### Final Answer:
The male gametes in Ginkgoales are motile.
