Cell Structure and Function Concepts

What three things do all cells have in common?

• Cell membrane, cytoplasm, and DNA

• Nucleus, organelles, and cell wall

• Mitochondria, ribosomes, and cytoplasm

• DNA, cell wall, and nucleus

Which of the following is a characteristic of eukaryotic cells?

• They are always unicellular organisms

• They lack a nucleus

• They contain membrane-enclosed organelles

• They are simpler than prokaryotic cells

What distinguishes prokaryotic cells from eukaryotic cells?

• Prokaryotic cells are always multicellular

• Prokaryotic cells contain a nucleus

• Prokaryotic cells lack membrane-enclosed organelles

• Prokaryotic cells have more complex structures

What is the primary function of the nucleus in a cell?

• To synthesize proteins

• To store water and waste

• To control cell activities and store genetic material

• To break down cellular debris

What is the main role of ribosomes and the endoplasmic reticulum (ER) in a cell?

• Energy production and waste removal

• Protein synthesis and transport

• Genetic material storage and cell division

• Structural support and movement

How does the Golgi apparatus customize proteins?

• By breaking them down into smaller molecules

• By storing them in vacuoles

• By folding them into usable shapes or adding other materials

• By converting them into energy

Which organelles are responsible for breaking down cellular waste and producing energy for the cell?

• Ribosomes and Endoplasmic Reticulum

• Lysosomes and Mitochondria

• Vacuoles and Chloroplasts

• Cytoskeleton and Nucleus

Which two structures are typically found in plant cells but not in animal cells?

• Nucleus and Mitochondria

• Cell membrane and Cytoplasm

• Chloroplasts and Cell Wall

• Ribosomes and Endoplasmic Reticulum
