What is an organ?

1. A group of cells in a tissue.
2. A group of cells performing the same task.
3. A combination of tissues.
4. A group of two or more tissue types that form a recognisable structure, and has a specific function in the body.

To which organ system does the lower jaw belong?

1. To the digestive system, because it is part of the mouth.
2. To the skeletal system, because it is a bone.
3. To the respiratory system, because it is part of the mouth.
4. To all of the above.

In animals as well as in plants, there is a wide variety of organ systems that have the same function.

Which of the following is an example of organ systems that have the same function?

1. Respiratory system: gills in fish / lungs in mammals.
2. Skeletal system: the wings of a bat / the arms of a human.
3. Respiratory system: leaves of a plant / lungs in mammals.
4. All of the above.

Carnivorous plants are plants that trap flies and other insects, which they use to get their nutrients. Examples of carnivorous plants are the pitcher plant, and the Venus fly trap. These plants trap insects in their flowers or their leaves.

The insects need to be broken down by the plant. Therefore, flowers and leaves of carnivorous plants belong to the …

2. Digestive system.
3. Reproductive system.
4. Respiratory system.

Which of the following is not a tissue?

1. The lining of the stomach.
2. Plant root.
3. Plant root hair tissue.
4. Muscle.

What is the correct order of the building blocks of a body or plant?

Cells are very small building blocks.

Why, do you think, are cells so small?

1. Cells need to move between very small areas.
2. Because it is better to have many cells than to have large cells.
