Tick the wrong statement

Options

A. Mature mammalian erythrocytes are without nucleus
B. All dead cells are without nucleus
C. Mature sieve tube cells of cryptogams are without nucleus
D. All eukaryotic cells are with nuclear membrane .

Answer

To solve the question of identifying the wrong statement, we will analyze each option provided.

### Step-by-Step Solution:

1. **Analyze Option A:** "Mature mammalian erythrocytes are without nucleus."
- This statement is **correct**. Mature mammalian red blood cells (erythrocytes) do not have a nucleus. This adaptation allows for more space to carry hemoglobin, which is essential for oxygen transport.

2. **Analyze Option B:** "All dead cells are without nucleus."
- This statement is **incorrect**. Not all dead cells lack a nucleus. For example, some cells may still retain their nuclei even after they have died. Therefore, this statement is potentially misleading and can be considered wrong.

3. **Analyze Option C:** "Matured seed tube cells of Cryptogams are without Nucleus."
- This statement is **incorrect**. Mature seed tube cells in Cryptogams (non-flowering plants) typically do have a nucleus. Thus, this statement is also wrong.

4. **Analyze Option D:** "All eukaryotic cells are with nuclear membrane."
- This statement is **correct**. Eukaryotic cells are characterized by the presence of a nucleus enclosed within a nuclear membrane.

### Conclusion:
The wrong statements identified are **Option B** and **Option C**. However, since the question asks for a single wrong statement, we can conclude that **Option C** is the most directly incorrect based on the context of mature cells.

### Final Answer:
**Option C: Matured seed tube cells of Cryptogams are without Nucleus.**
