Read the following statements w.r.t. protista. [(a) They have 80 S cytoplasmic ribosomes., (b) Flagella and cilia have 9+0 pattern of microtubule organization., (c) Ciliary mode of movement is faster than flagellated movement protista., (d) Some protists have mixotrophic nutrition., (e) acellular slime moulds are photosynthetic protozoans.]

Options

A. (a),(c) & (e)
B. (a),(c) & (d)
C. (a),(b),(c) & (d)
D. (a), (c) ,(d) &(e)

Answer

To analyze the statements regarding Protista, we will evaluate each statement one by one.

### Step-by-Step Solution:

1. **Statement (a): They have 80 S cytoplasmic ribosomes.**
- **Analysis:** This statement is **correct**. Protists typically have both 80S ribosomes in their cytoplasm and 70S ribosomes in their organelles like mitochondria and plastids.

2. **Statement (b): Flagella and cilia have 9+0 pattern of microtubule organization.**
- **Analysis:** This statement is **incorrect**. Flagella and cilia actually have a 9+2 arrangement of microtubules, where there are nine doublet microtubules surrounding two central microtubules.

3. **Statement (c): Ciliary mode of movement is faster than flagellated movement in Protista.**
- **Analysis:** This statement is **correct**. Cilia can beat in a coordinated manner, allowing for faster movement compared to flagella, which typically move in a whip-like motion.

4. **Statement (d): Some protists have mixotrophic nutrition.**
- **Analysis:** This statement is **correct**. Some protists, like Euglena, can perform both photosynthesis and heterotrophy, thus exhibiting mixotrophic nutrition.

5. **Statement (e): Acellular slime molds are photosynthetic protozoans.**
- **Analysis:** This statement is **incorrect**. Acellular slime molds (like those in the group Myxomycetes) are not photosynthetic; they are heterotrophic and feed on decaying organic matter. Euglena is an example of a photosynthetic protist, not acellular slime molds.

### Summary of Correct Statements:
- Correct statements are (a), (c), and (d).
- Incorrect statements are (b) and (e).

### Final Answer:
The correct answer is **Statements (a), (c), and (d) are true.**
