Quiz on Cell Organelles and Their Functions

What is the primary function of mitochondria in a cell?

• Photosynthesis

• Protein synthesis

• Digestion of waste

• Energy production

Answer explanation

The primary function of mitochondria in a cell is energy production, not photosynthesis, protein synthesis, or digestion of waste.

Which organelle is known as the 'Powerhouse of the Cell'?

• Nucleus

• Mitochondria

• Golgi Apparatus

• Endoplasmic Reticulum

Answer explanation

The organelle known as the 'Powerhouse of the Cell' is the Mitochondria, as it is responsible for producing energy in the form of ATP through cellular respiration.

What is the main function of the Golgi apparatus?

• Energy production

• Protein synthesis

• Transporting and modifying proteins

• Storing nutrients

Answer explanation

The main function of the Golgi apparatus is transporting and modifying proteins.

Which cell organelle is responsible for photosynthesis?

• Lysosome

• Mitochondria

• Ribosome

• Chloroplast

Answer explanation

The cell organelle responsible for photosynthesis is the Chloroplast.

What type of organelle is the nucleus?

• Single membrane-bound

• Double membrane-bound

• Non-membrane bound

• No membrane

Answer explanation

The nucleus is a double membrane-bound organelle.

Which organelle is primarily involved in the synthesis of lipids?

• Smooth Endoplasmic Reticulum

• Rough Endoplasmic Reticulum

• Golgi Apparatus

• Nucleus

Answer explanation

The organelle primarily involved in the synthesis of lipids is the Smooth Endoplasmic Reticulum.

What is the function of ribosomes?

• Digestion

• Photosynthesis

• Energy production

• Protein synthesis

Answer explanation

The function of ribosomes is protein synthesis, not digestion, photosynthesis, or energy production.

What is the main function of the plasma membrane?

• Energy storage

• Photosynthesis

• Selective permeability to substances

• Protein synthesis

Answer explanation

The main function of the plasma membrane is selective permeability to substances, allowing certain molecules to pass through while blocking others.

Which organelle contains chlorophyll in plant cells?

• Mitochondria

• Chloroplast

• Golgi Apparatus

• Ribosome

Answer explanation

The organelle that contains chlorophyll in plant cells is the Chloroplast, making it the correct choice.

What is the primary role of vacuoles in plant cells?

• Storing nutrients and waste products

• Breaking down waste

• Protein synthesis

• Energy production

Answer explanation

The primary role of vacuoles in plant cells is storing nutrients and waste products, helping maintain cell turgor pressure and regulating cell functions.
