What structure controls the movement of substances in and out of the cell?

• Nucleus

• Ribosome

• Cytoplasm

• Cell membrane

Which organelle is known as the 'powerhouse' of the cell?

• Ribosome

• Chloroplast

• Nucleus

• Mitochondria

What is the function of ribosomes in a cell?

• To transport nutrients within the cell

• The function of ribosomes in a cell is to synthesize proteins.

• To store genetic information

• To generate energy for cellular processes

Describe the role of the endoplasmic reticulum.

• The endoplasmic reticulum generates energy for the cell.

• The endoplasmic reticulum acts as the cell's waste disposal system.

• The endoplasmic reticulum synthesizes proteins and lipids, and transports materials within the cell.

• The endoplasmic reticulum is responsible for DNA replication.

What is the function of the Golgi apparatus?

• To produce energy for the cell

• To synthesize DNA and RNA

• The function of the Golgi apparatus is to modify, sort, and package proteins and lipids for secretion or delivery to other organelles.

• To store waste products and toxins

Which part of the cell contains genetic material?

• Ribosomes

• Mitochondria

• Endoplasmic reticulum

• Nucleus (in eukaryotic cells) or nucleoid (in prokaryotic cells)

What is the difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells can be multicellular; eukaryotic cells are unicellular.

• Eukaryotic cells are always smaller than prokaryotic cells.

• Prokaryotic cells have a nucleus; eukaryotic cells do not.

• Prokaryotic cells do not have a nucleus or membrane-bound organelles; eukaryotic cells do.

What is the function of lysosomes in a cell?

• The function of lysosomes in a cell is to digest and break down waste materials and cellular debris.

• To synthesize proteins

• To store genetic information

• To produce energy for the cell
