Cells are organized into tissues, organs, and systems to perform functions that cannot be carried out by single cells. This is because each type of cell, tissue, organ, and system has a specific function that contributes to the overall functioning of the organism.

For example, a single cell cannot digest food, but a system of cells (the digestive system) can. Similarly, a single cell cannot pump blood throughout the body, but an organ made up of many cells (the heart) can.

This organization also allows for specialization. For example, nerve cells are specialized to transmit signals, while blood cells are specialized to carry oxygen.

So, the correct answer is A: Cells are organized into tissues, organs, and systems to perform functions that cannot be carried out by single cells.

Option B is incorrect because while cells do exchange gases like oxygen and carbon dioxide, this is not the primary reason they are organized into tissues, organs, and systems.
