A typical eukaryotic cell consists of :-

Options

A. Cell membrane
B. Nucleus
C. Cytoplasm
D. All of the above

Answer

To answer the question "A typical eukaryotic cell consists of:", we will analyze the components of a eukaryotic cell step by step.

### Step 1: Identify the Components of a Eukaryotic Cell
A typical eukaryotic cell is characterized by several key components. The main parts include:

1. **Cell Membrane**: This is the outer boundary of the cell, which controls the movement of substances in and out of the cell. It is composed of a phospholipid bilayer with embedded proteins.

2. **Nucleus**: The nucleus is a membrane-bound organelle that contains the cell's genetic material (DNA). It is surrounded by a nuclear membrane and is responsible for regulating gene expression and maintaining the integrity of genes.

3. **Cytoplasm**: This is the jelly-like substance that fills the interior of the cell, where various organelles are suspended. It is the site for many metabolic processes and contains cytosol, organelles, and various molecules.

### Step 2: Additional Organelles
In addition to the three main components mentioned above, a typical eukaryotic cell also contains various organelles, such as:

- **Ribosomes**: These are the sites of protein synthesis.
- **Endoplasmic Reticulum (ER)**: This organelle is involved in the synthesis of proteins (rough ER) and lipids (smooth ER).
- **Golgi Apparatus**: It modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
- **Mitochondria**: Known as the powerhouse of the cell, mitochondria are responsible for energy production through cellular respiration.
- **Chloroplasts**: Present in plant cells, chloroplasts are involved in photosynthesis.

### Step 3: Conclusion
Based on the components and organelles identified, we can conclude that a typical eukaryotic cell consists of:

- Cell Membrane
- Nucleus
- Cytoplasm
- Additional organelles (like ribosomes, ER, Golgi apparatus, mitochondria, and chloroplasts)

Thus, the correct answer to the question is **"all of the above"**.

### Final Answer
A typical eukaryotic cell consists of: **Cell Membrane, Nucleus, Cytoplasm, and all of the above.**
