Choose the correct statement

Options

A. All the members of Phycomycetes are facultative parasites on plants
B. Fusion of protoplasm between two motile or non-motile gametes is called plasmogamy
C. Kingdom Plantae includes all eukaryotic chlorophyll containing organisms and non-chlorophyll organisms and are called plants
D. Trichoderma belongs to basidiomycetes

Answer

To solve the question "Choose the correct statement," we will analyze each option provided and determine which one is accurate based on biological classification principles.

### Step-by-Step Solution:

1. **Analyze Option 1:**
- Statement: "All the members of phycomycetes are facultative parasites on plants."
- Analysis: Phycomycetes (now often referred to as Zygomycetes) primarily include obligate parasites, not facultative ones. Therefore, this statement is incorrect.

2. **Analyze Option 2:**
- Statement: "The fusion of protoplasm between two motile and non-motile gametes is called plasmogamy."
- Analysis: Plasmogamy is indeed the fusion of the cytoplasm of two gametes, which can be either motile or non-motile. This statement is correct.

3. **Analyze Option 3:**
- Statement: "Kingdom Plantae includes all eukaryotic chlorophyll-containing organisms and non-chlorophyll organisms and are called plants."
- Analysis: Kingdom Plantae primarily includes eukaryotic organisms that contain chlorophyll. Non-chlorophyll organisms are not classified under Plantae. Thus, this statement is incorrect.

4. **Analyze Option 4:**
- Statement: "Typhoderma belongs to basidomycetes."
- Analysis: Typhoderma is not classified under Basidiomycetes; it belongs to Deuteromycetes (also known as Fungi Imperfecti). Therefore, this statement is incorrect.

### Conclusion:
The only correct statement among the provided options is **Option 2**: "The fusion of protoplasm between two motile and non-motile gametes is called plasmogamy."
