OST Review 2: Cell Organelles & Transport

Which organelle is only found in plant cells?

• Mitochondria

• Chloroplast

• Ribosome

• Endoplasmic Reticulum

What is the function of ribosomes?

• Ribosomes are responsible for energy production.

• Ribosomes are responsible for protein synthesis.

• Ribosomes are responsible for DNA replication.

• Ribosomes are responsible for lipid synthesis.

What is the function of mitochondria?

• Mitochondria are responsible for protein synthesis.

• Mitochondria are the powerhouse of the cell, producing energy through cellular respiration.

• Mitochondria help in the detoxification of harmful substances.

• Mitochondria are involved in the storage of genetic information.

What is a vacuole?

• A type of cell that produces energy

• A storage organelle that can hold various substances, including nutrients and waste products.

• A structure that helps in cell division

• A part of the cell responsible for protein synthesis

What is a hypertonic solution?

• A solution with a lower concentration of solutes compared to the inside of the cell.

• A solution with an equal concentration of solutes compared to the inside of the cell.

• A hypertonic solution has a higher concentration of solutes compared to the inside of the cell.

• A solution that causes cells to swell and burst.

What is the role of the cell membrane?

• It provides structural support to the cell.

• It controls what enters and exits the cell, maintaining homeostasis.

• It stores genetic information for the cell.

• It produces energy for the cell.

What is the significance of the fluid mosaic model?

• It describes the structure of cell membranes as a rigid layer made of proteins only.

• It explains how cells communicate with each other through chemical signals.

• It describes the structure of cell membranes as a flexible layer made of lipid molecules with embedded proteins.

• It outlines the process of cellular respiration in mitochondria.

What is the function of the nucleus?

• It produces energy for the cell.

• It houses the cell's genetic material and controls cellular activities.

• It helps in the synthesis of proteins.

• It regulates the cell's waste disposal.

What is the function of lysosomes?

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

• Lysosomes are responsible for protein synthesis in the cell.

• Lysosomes help in the production of energy in the form of ATP.

• Lysosomes are involved in the transport of nutrients across the cell membrane.

What is the main difference between passive and active transport?

• Active transport requires energy, while passive transport does not.

• Passive transport requires energy, while active transport does not.

• Both active and passive transport require energy.

• Active transport occurs only in plants, while passive transport occurs in animals.
