Cell Structure and Function Concepts

What three things do all cells have in common?

• Cell wall, nucleus, cytoplasm

• Cell membrane, cytoplasm, DNA

• Mitochondria, cell membrane, DNA

• Nucleus, ribosomes, cell membrane

Which type of cell lacks a nucleus and membrane-enclosed organelles?

• Eukaryotic cells

• Plant cells

• Prokaryotic cells

• Animal cells

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

• To produce energy for the cell

• To synthesize proteins

• To control cell activities by dictating what the cell does

• To store water and waste materials

What is the main job of ribosomes after they leave the nucleolus?

• To break down cellular debris

• To synthesize proteins

• To store genetic material

• To provide structural support

What is the function of the endoplasmic reticulum (ER)?

• To generate ATP through cellular respiration

• To store genetic information

• To transport materials like proteins throughout the cell

• To customize proteins into usable forms

What is the role of the Golgi apparatus (Golgi body) in the cell?

• To produce ribosomes

• To break down waste products

• To store water

• To customize proteins into usable forms

Which organelle is responsible for breaking down damaged or worn-out cell parts using enzymes?

• Mitochondrion

• Lysosome

• Vacuole

• Chloroplast

What is the primary function of mitochondria in both animal and plant cells?

• To perform photosynthesis

• To store genetic material

• To produce ATP molecules for energy

• To provide structural support

Which of the following structures are unique to plant cells and not found in animal cells?

• Nucleus and cytoplasm

• Cell membrane and mitochondria

• Chloroplasts and cell wall

• Ribosomes and endoplasmic reticulum

Which structures are hair-like or tail-like projections that help cells move or trap particles?

• Microfilaments and microtubules

• Chromosomes and chromatin

• Cilia and flagella

• Vesicles and vacuoles
