What is the main function of the mitochondria?

• Regulate cell division

• Produce oxygen

• Produce energy through cellular respiration

• Store genetic material

Which organelle is involved in aerobic respiration?

• mitochondria

• lysosomes

• endoplasmic reticulum

• ribosomes

What is the function of the endoplasmic reticulum?

• Protein and lipid synthesis, transportation of molecules

• Energy production, waste removal

• Water absorption, gas exchange

• Cell division, DNA replication

Which organelle contains digestive enzymes to break down waste materials?

• ribosome

• nucleus

• lysosome

• mitochondria

What is the function of the Golgi apparatus?

• Generating energy for the cell

• Modifying, sorting, and packaging proteins and lipids

• Regulating cell division

• Storing genetic information

What is the function of the cytoskeleton in a cell?

• Photosynthesis, respiration, digestion

• Cell division, protein synthesis, signal transduction

• Energy production, waste removal, DNA replication

• Structural support, cell movement, intracellular transport

Which organelle is involved in lipid synthesis?
