Which option is correct regarding eukeryotic Cell:-

Options

A. Cytoplasm of Eukaryotic cell catain 70 s and 80 s ribosome
B. Eukeryotic cell contain linear ds DNA in chloroplast and mitochondria
C. Only 80s ribosomes are found in cytoplasm mitochondria and chloroplast of eukaryotic cell
D. 80s ribosomes are present in cytoplasm of eukaryotic cell only

Answer

To determine which option is correct regarding eukaryotic cells, let's analyze each statement step by step.

### Step 1: Analyze the First Option
**Statement:** "Cytoplasm of eukaryotic cells contain 70s and 80s ribosomes."

**Analysis:**
- In eukaryotic cells, the cytoplasm primarily contains 80S ribosomes.
- 70S ribosomes are typically found in prokaryotic cells and in the mitochondria and chloroplasts of eukaryotic cells, not in the cytoplasm.

**Conclusion:** This statement is incorrect.

### Step 2: Analyze the Second Option
**Statement:** "Eukaryotic cells contain linear double-stranded DNA in chloroplasts and mitochondria."

**Analysis:**
- While eukaryotic cells do have DNA in chloroplasts and mitochondria, this DNA is circular, not linear.
- Chloroplasts and mitochondria contain their own DNA, which is similar to bacterial DNA (circular).

**Conclusion:** This statement is also incorrect.

### Step 3: Analyze the Third Option
**Statement:** "Only 80S ribosomes are found in cytoplasm, mitochondria, and chloroplasts of eukaryotic cells."

**Analysis:**
- This statement is misleading. While the cytoplasm contains 80S ribosomes, mitochondria and chloroplasts contain 70S ribosomes.
- Therefore, it is incorrect to say that only 80S ribosomes are present in all these locations.

**Conclusion:** This statement is incorrect.

### Step 4: Analyze the Fourth Option
**Statement:** "80S ribosomes are present in the cytoplasm of eukaryotic cells."

**Analysis:**
- This statement is accurate. Eukaryotic cells do indeed contain 80S ribosomes in their cytoplasm.

**Conclusion:** This statement is correct.

### Final Answer
The correct option regarding eukaryotic cells is: **"80S ribosomes are present in the cytoplasm of eukaryotic cells."**
