The correct Answer is:
To determine how many of the statements about protists are true, we will evaluate each statement one by one. ### Step 1: Evaluate Statement I **Statement I:** Euglenoids have a carbohydrate-rich layer called pellicle. - **Analysis:** Euglenoids are unicellular flagellate protists. They do not have a cell wall; instead, they have a flexible layer called the pellicle. However, the pellicle is primarily composed of proteins, not carbohydrates. Therefore, this statement is **false**. ### Step 2: Evaluate Statement II **Statement II:** Slime moulds are saprophytic fungi. - **Analysis:** Slime moulds are indeed saprophytic, meaning they feed on dead and decaying organic matter. However, they are not classified as fungi; they are classified as protists. Therefore, this statement is also **false**. ### Step 3: Evaluate Statement III **Statement III:** Dinoflagellates are mostly found in fresh water and are photosynthetic. - **Analysis:** Dinoflagellates are primarily marine organisms and are known for their photosynthetic capabilities. While some dinoflagellates can be found in fresh water, they are predominantly marine. Thus, this statement is **false**. ### Step 4: Evaluate Statement IV **Statement IV:** Spores of slime moulds are dispersed by water. - **Analysis:** Spores of slime moulds are actually dispersed by wind, not water. Therefore, this statement is also **false**. ### Conclusion After evaluating all four statements, we find that **none of the statements are true**. Therefore, the total number of true statements is **0**. ### Final Answer The number of true statements is **0**. ---
