Cell Organelles and Transport Review

Front

What is an isotonic solution?

Back

An isotonic solution is a solution that has the same concentration of solutes as another solution, resulting in no net movement of water across a semipermeable membrane.

Front

What organelle is responsible for making proteins?

Back

Ribosomes are the organelles that synthesize proteins by translating messenger RNA.

Front

In which direction do particles move during diffusion?

Back

Particles move from an area of high concentration to an area of low concentration during diffusion.

Front

What are lysosomes?

Back

Lysosomes are organelles that contain digestive enzymes to break down waste materials and cellular debris.

Front

What process removes carbon dioxide (CO2) from cells without using energy?

Back

Diffusion is the process that allows carbon dioxide to move out of cells without the use of energy.

Front

What is the function of the mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the role of the endoplasmic reticulum?

Back

The endoplasmic reticulum (ER) is involved in the synthesis of proteins and lipids; it can be rough (with ribosomes) or smooth (without ribosomes).

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What are vacuoles?

Back

Vacuoles are storage organelles in cells that can hold various substances, including nutrients, waste products, and water.
