Cell that has membrane bound nucleus is called (A)_____ whereas cell that lack membrane bound nucleus is called (B)_____

Answer

To answer the question, we need to identify the two types of cells based on the presence or absence of a membrane-bound nucleus.

**Step 1: Understand the types of cells**
- Cells can be classified into two main categories based on the presence of a nucleus: eukaryotic cells and prokaryotic cells.

**Step 2: Define eukaryotic cells**
- Eukaryotic cells are characterized by having a membrane-bound nucleus. This means that the genetic material (DNA) is enclosed within a nuclear membrane. Examples of eukaryotic cells include those found in humans, animals, plants, and fungi.

**Step 3: Define prokaryotic cells**
- Prokaryotic cells, on the other hand, lack a membrane-bound nucleus. Their genetic material is not enclosed in a nuclear membrane, and it is typically found in a region called the nucleoid. Bacteria and archaea are examples of prokaryotic cells.

**Step 4: Fill in the blanks**
- Based on the definitions:
- (A) Cell that has a membrane-bound nucleus is called **eukaryotic cell**.
- (B) Cell that lacks a membrane-bound nucleus is called **prokaryotic cell**.

**Final Answer:**
(A) Eukaryotic cell, (B) Prokaryotic cell.
