The pollination in Pinus is

Options

A. Entomophilous
B. Anemophilous
C. Hydrophilous
D. Malacophilous

Answer

To determine the type of pollination in Pinus, we need to analyze the options provided and understand the characteristics of each type of pollination.

### Step-by-Step Solution:

1. **Understanding Pollination**: Pollination is the process of transferring pollen grains from the male part (anther) of a flower to the female part (stigma) of the same or another flower. This is crucial for fertilization and reproduction in plants.

2. **Identifying the Options**:
- **Entomophilous**: This refers to pollination by insects. Insects like bees, butterflies, and beetles are involved in this process. Examples include flowering plants like roses and jasmines.
- **Anemophilous**: This refers to wind pollination. In this process, pollen grains are carried by the wind to the stigma. Plants that exhibit this type of pollination typically produce a large quantity of lightweight pollen. Gymnosperms, including Pinus, are known for this type of pollination.
- **Hydrophilus**: This refers to water pollination, where pollen is transferred through water. An example of a plant that uses this method is hydrilla.
- **Malecophilus**: This type of pollination involves snails or slugs. An example of a plant that utilizes this method is Lemna.

3. **Analyzing Pinus**: Pinus is a genus of coniferous trees, commonly known as pines. These trees produce a significant amount of pollen that is lightweight and can be easily carried by the wind. Therefore, they are classified as anemophilous plants.

4. **Conclusion**: Based on the characteristics of Pinus and the definitions of the types of pollination, it is clear that the correct answer is **anemophilous**, which means that Pinus undergoes wind pollination.

### Final Answer:
The pollination in Pinus is **anemophilous**.
