Cell Structure and Function Quiz

• To synthesize DNA during replication
• To provide structural support to the nucleolus
• To regulate the movement of molecules such as RNA and proteins between the nucleus and cytoplasm
• To initiate cell division

• It produces energy for the cell
• It synthesizes lipids and carbohydrates
• It stores and protects genetic material and controls cellular activities
• It facilitates cell movement

• It dissolves completely during cell division
• It only participates in meiosis
• It stores energy for cell division
• It participates in mitotic and meiotic cell divisions to ensure genetic continuity

• Heterochromatin is loosely coiled and genetically active
• Heterochromatin is highly coiled and genetically less active, while euchromatin is loosely coiled and more active
• Euchromatin is dark-staining and inactive
• Heterochromatin lacks DNA

• Chromatin
• Nuclear membrane
• Nucleolus
• Nuclear pore
