Which of the following is NOT a component of a eukaryotic cell?

  1. Nucleus

  2. Cell Membrane

  3. Cell Wall

  4. Mitochondria


Correct Option: C
Explanation:

Cell walls are found in plant cells, but not in animal cells.

What is the function of the cell membrane?

  1. Controls the movement of substances in and out of the cell

  2. Provides structural support to the cell

  3. Contains the cell's genetic material

  4. Produces energy for the cell


Correct Option: A
Explanation:

The cell membrane is selectively permeable, allowing certain substances to pass through while blocking others.

Which organelle is responsible for producing energy in the cell?

  1. Nucleus

  2. Mitochondria

  3. Endoplasmic Reticulum

  4. Golgi Apparatus


Correct Option: B
Explanation:

Mitochondria are often called the 'powerhouses of the cell' because they produce most of the cell's energy through cellular respiration.

What is the function of the Golgi apparatus?

  1. Packages and distributes proteins and lipids

  2. Produces ribosomes

  3. Synthesizes DNA

  4. Breaks down waste products


Correct Option: A
Explanation:

The Golgi apparatus modifies, sorts, and packages proteins and lipids, and then distributes them to other parts of the cell or outside the cell.

Which type of tissue is responsible for contracting and relaxing muscles?

  1. Epithelial Tissue

  2. Connective Tissue

  3. Muscle Tissue

  4. Nervous Tissue


Correct Option: C
Explanation:

Muscle tissue is responsible for movement and is classified into three types: skeletal muscle, smooth muscle, and cardiac muscle.

What is the function of connective tissue?

  1. Provides structural support and protection

  2. Transmits nerve impulses

  3. Produces hormones

  4. Absorbs nutrients


Correct Option: A
Explanation:

Connective tissue provides structural support and protection to organs and tissues, and also helps in binding them together.

Which type of tissue lines the inner surfaces of organs and cavities?

  1. Epithelial Tissue

  2. Connective Tissue

  3. Muscle Tissue

  4. Nervous Tissue


Correct Option: A
Explanation:

Epithelial tissue forms a protective barrier between the internal environment of the body and the external environment.

What is the function of nervous tissue?

  1. Transmits nerve impulses

  2. Produces hormones

  3. Absorbs nutrients

  4. Provides structural support


Correct Option: A
Explanation:

Nervous tissue is responsible for transmitting nerve impulses, which allow communication between different parts of the body.

Which of the following is NOT a type of cell division?

  1. Mitosis

  2. Meiosis

  3. Binary Fission

  4. Budding


Correct Option: D
Explanation:

Budding is a type of asexual reproduction, not cell division.

What is the purpose of mitosis?

  1. Cell growth and repair

  2. Production of gametes

  3. Genetic variation

  4. Cell differentiation


Correct Option: A
Explanation:

Mitosis is responsible for cell growth and repair, producing two genetically identical daughter cells.

What is the significance of meiosis?

  1. Production of gametes

  2. Cell growth and repair

  3. Genetic variation

  4. Cell differentiation


Correct Option: A
Explanation:

Meiosis is responsible for producing gametes (sex cells), which have half the number of chromosomes as somatic cells.

Which of the following is NOT a type of cell differentiation?

  1. Myoblast to muscle cell

  2. Stem cell to nerve cell

  3. Zygote to embryo

  4. Cell division


Correct Option: D
Explanation:

Cell division is not a type of cell differentiation, but rather a process by which cells divide to produce new cells.

What is the role of stem cells in cell differentiation?

  1. They can differentiate into various cell types

  2. They produce gametes

  3. They provide structural support

  4. They transmit nerve impulses


Correct Option: A
Explanation:

Stem cells have the ability to differentiate into various cell types, giving rise to specialized cells with specific functions.

Which of the following is NOT a type of tissue organization?

  1. Epithelial Tissue

  2. Connective Tissue

  3. Muscle Tissue

  4. Organ System


Correct Option: D
Explanation:

Organ system is a level of organization above tissues, consisting of groups of organs working together to perform a specific function.

What is the function of an organ system?

  1. Performs a specific function

  2. Provides structural support

  3. Transmits nerve impulses

  4. Absorbs nutrients


Correct Option: A
Explanation:

An organ system is a group of organs working together to perform a specific function, such as the digestive system or the respiratory system.
