Cell Organelles

What are centrioles?

• Cylindrical structures that help in cell division by organizing the mitotic spindle.

• Small organelles that produce energy for the cell.

• Structures that store genetic information in the nucleus.

• Components of the cell membrane that regulate transport.

What is the function of vacuoles?

• Storage organelles that hold various substances, such as nutrients and waste products.

• Sites of protein synthesis in the cell.

• Organelles responsible for energy production.

• Components of the cell membrane that regulate transport.

What is the function of the nucleolus?

• Produces ribosomes

• Synthesizes DNA

• Transports proteins

• Regulates cell division

What is chromatin?

• A type of RNA found in the cytoplasm.

• A complex of DNA and proteins found in the nucleus that condenses to form chromosomes.

• A structure that only exists in prokaryotic cells.

• A type of lipid that forms the cell membrane.

What is the purpose of the Golgi apparatus?

• To produce energy for the cell

• To modify, sort, and package proteins and lipids for secretion

• To synthesize DNA and RNA

• To transport materials within the cell

What is the function of lysosomes?

• To synthesize proteins

• To break down waste materials and cellular debris

• To produce energy for the cell

• To store genetic information

What is the role of the cell membrane?

• A protective barrier that regulates what enters and leaves the cell.

• A structure that provides energy to the cell.

• A component that stores genetic information.

• A site for protein synthesis.

What is the function of mitochondria?

• Produce energy (ATP) through cellular respiration.

• Store genetic information.

• Synthesize proteins for the cell.

• Transport nutrients across the cell membrane.

What are the 'envelopes' of the cell used for transporting material?

• Vesicles: Small membrane-bound sacs that transport substances within the cell.

• Cilia: Hair-like structures that help in cell movement.

• Ribosomes: Organelles that synthesize proteins.

• Lysosomes: Organelles that digest waste materials.

What structure provides support and shape to plant cells?

• Cell Membrane

• Cell Wall

• Chloroplast

• Nucleus
