Cell Parts Quizs

What is the function of the cell membrane?

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

• A structure that provides energy to the cell.

• A component that stores genetic information.

• A site for protein synthesis.

What is the role of the plasma membrane?

• A selectively permeable barrier that controls the movement of substances in and out of the cell.

• A rigid structure that provides support to the cell.

• A site for energy production through cellular respiration.

• A component that stores genetic information.

What is the function of lysosomes?

• To synthesize proteins

• To contain enzymes that break down waste materials and cellular debris.

• To produce energy for the cell

• To store genetic information

What is the role of chloroplasts in plant cells?

• To conduct photosynthesis, converting light energy into chemical energy.

• To store nutrients and water for the plant.

• To provide structural support to the plant cell.

• To facilitate cellular respiration in the plant.

What is the function of the Golgi body?

• Modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

• Produces ATP for cellular energy.

• Synthesizes ribosomal RNA for protein synthesis.

• Transports materials within the cell.

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

• A network of membranes involved in protein and lipid synthesis.

• A structure responsible for energy production in the cell.

• A component of the cell membrane that regulates transport.

• A site for DNA replication and repair.

What is the role of the ribosome in a cell?

• The site of protein synthesis, where amino acids are assembled into proteins.

• The location where DNA is replicated.

• The organelle responsible for energy production in the cell.

• The structure that helps in the transport of materials within the cell.

Do bacteria have cell walls?

• Yes, all bacteria have cell walls made of peptidoglycan.

• No, bacteria do not have cell walls.

• Yes, but only some bacteria have cell walls.

• Yes, all bacteria have cell walls, but they are made of different materials.

What is the role of the nucleolus?

• Produces ribosomal RNA (rRNA) and assembles ribosome subunits.

• Synthesizes DNA for cell division.

• Regulates the cell cycle and apoptosis.

• Stores genetic information in the form of chromosomes.

What is the function of the cytoplasm?

• To provide energy for the cell

• To hold organelles in place

• To control cell division

• To transport nutrients within the cell
