Cell Structure and Function

What is the significance of membrane-bound organelles in eukaryotic cells?

• They help in cell movement
• They store extra DNA
• They allow compartmentalization of metabolic activities
• They provide structural support to the cell wall

Why is the cell membrane vital for the survival of a cell?

• It provides rigid structural support to the cell
• It synthesizes proteins for the cell
• It stores genetic information
• It regulates the movement of substances in and out of the cell

Which cell organelles are capable of self-duplication?

• Lysosomes and peroxisomes
• Endoplasmic reticulum and Golgi bodies
• Ribosomes and centrioles
• Mitochondria and chloroplasts

What is the main function of the nucleus in a eukaryotic cell?

• To produce energy for the cell
• To modify proteins for secretion
• To store water and nutrients
• To store genetic material and control cellular activities

Which of the following organelles is responsible for protein modification and packaging?

• Ribosome
• Endoplasmic reticulum
• Lysosome
• Golgi apparatus
