Read the following statements about protists and state how many of them are true
(I) Euglenoids have a Carbohydrate rich layer called pellicle.
(II) Slime moulds are Saprophytic fungi .
(III) Dinoflagellates are mostly found in fresh water and are photosynthetic
(IV) spores of slime moulds are dispersed bye water.

Options

A. One
B. Two
C. Three
D. zero

Answer

To determine how many of the provided statements about protists are true, we will evaluate each statement one by one.

**Step 1: Evaluate Statement I**
- Statement: Euglenoids have a carbohydrate-rich layer called pellicle.
- Analysis: Euglenoids do not possess a cell wall; instead, they have a pellicle, which is a protein-rich layer. Therefore, this statement is incorrect.

**Step 2: Evaluate Statement II**
- Statement: Slime moulds are saprophytic fungi.
- Analysis: Slime moulds are not classified as fungi, even though they exhibit a life cycle similar to fungi. They are categorized as protists. Hence, this statement is also incorrect.

**Step 3: Evaluate Statement III**
- Statement: Dinoflagellates are mostly found in fresh water and are photosynthetic.
- Analysis: Dinoflagellates are primarily found in marine environments, not fresh water. While some dinoflagellates are photosynthetic, many are mixotrophic, meaning they can obtain energy through both photosynthesis and heterotrophy. Therefore, this statement is incorrect.

**Step 4: Evaluate Statement IV**
- Statement: Spores of slime moulds are dispersed by water.
- Analysis: Slime moulds produce spores during their pseudoplasmodium phase, but these spores are not primarily dispersed by water. They are typically dispersed by wind or other means. Thus, this statement is also incorrect.

**Conclusion:**
After evaluating all four statements, we find that none of them are true. Therefore, the answer to the question is that **0 statements are true**.

### Summary of True Statements:
- Statement I: Incorrect
- Statement II: Incorrect
- Statement III: Incorrect
- Statement IV: Incorrect

**Final Answer: 0 statements are true.**
