Unit 1 Cells and Body Systems Review Period 3

Front

What are sensory nerves?

Back

Sensory nerves are nerves that carry information from sensory receptors to the brain or spinal cord, allowing us to perceive sensations like touch, pain, and temperature.

Front

What is the role of the nucleus in a cell?

Back

The nucleus is the control center of the cell, often referred to as the 'queen' of the cell, as it contains the cell's genetic material and regulates all cellular activities.

Front

Which organelle is NOT found in animal cells?

Back

Chloroplasts are not found in animal cells; they are present in plant cells and are responsible for photosynthesis.

Front

What are motor nerves?

Back

Motor nerves are nerves that carry signals from the brain and spinal cord to muscles, enabling movement.

Front

What is the function of the spinal cord in the nervous system?

Back

The spinal cord acts as a pathway for signals between the brain and the rest of the body, transmitting messages related to touch and other sensations.

Front

What is the cell membrane?

Back

The cell membrane is a protective barrier that surrounds the cell, controlling what enters and exits the cell.

Front

What are mitochondria?

Back

Mitochondria are known as the 'powerhouses' of the cell, as they generate energy through the process of cellular respiration.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that capture sunlight and convert it into chemical energy through photosynthesis.

Front

What is the difference between sensory and motor nerves?

Back

Sensory nerves carry information to the brain, while motor nerves carry commands from the brain to muscles.

Front

What is the role of blood cells in the body?

Back

Blood cells, including red and white blood cells, are responsible for transporting oxygen, fighting infections, and maintaining overall health.
