A: Mitochondria; The flexible outer boundary of every cell that controls what enters and exits. Made of a phospholipid bilayer, it acts as a selective barrier maintaining the cell's internal environment.: Often called the powerhouse of the cell, mitochondria produce ATP energy through cellular respiration. They have their own DNA and are believed to have originated from ancient bacteria.

A: Nervous System; The flexible outer boundary of every cell that controls what enters and exits. Made of a phospholipid bilayer, it acts as a selective barrier maintaining the cell's internal environment.: The body's communication network consisting of the brain, spinal cord, and peripheral nerves. It transmits electrical signals to coordinate movement, sensation, and organ function.

Q: [...]: [...]
A: Cardiovascular System; The flexible outer boundary of every cell that controls what enters and exits. Made of a phospholipid bilayer, it acts as a selective barrier maintaining the cell's internal environment.: The circulatory system consisting of the heart, blood vessels, and blood. It delivers oxygen and nutrients to every cell while removing carbon dioxide and waste products.

Q: [...]: [...]
A: Homeostasis; The flexible outer boundary of every cell that controls what enters and exits. Made of a phospholipid bilayer, it acts as a selective barrier maintaining the cell's internal environment.: The process by which the body maintains stable internal conditions such as temperature, pH, and blood sugar despite changes in the external environment.

Q: [...]: [...]
A: Neuron; The flexible outer boundary of every cell that controls what enters and exits. Made of a phospholipid bilayer, it acts as a selective barrier maintaining the cell's internal environment.: The basic functional unit of the nervous system — a specialised cell that transmits electrical impulses. Each neuron has dendrites to receive signals and an axon to send them to the next cell.

Q: [...]: [...]
A: Endocrine System; The flexible outer boundary of every cell that controls what enters and exits. Made of a phospholipid bilayer, it acts as a selective barrier maintaining the cell's internal environment.: A network of glands that produce and release hormones directly into the bloodstream. It regulates metabolism, growth, reproduction, and mood through chemical signals.

Q: [...]: [...]
A: Respiratory System; The flexible outer boundary of every cell that controls what enters and exits. Made of a phospholipid bilayer, it acts as a selective barrier maintaining the cell's internal environment.: The system responsible for gas exchange — bringing oxygen into the body and expelling carbon dioxide. Key structures include the lungs, bronchi, trachea, and diaphragm.

Q: [...]: [...]
A: Immune System; The flexible outer boundary of every cell that controls what enters and exits. Made of a phospholipid bilayer, it acts as a selective barrier maintaining the cell's internal environment.: The body's defence network against pathogens including bacteria, viruses, and foreign substances. It includes white blood cells, antibodies, and the lymphatic system.

Q: [...]: [...]
A: DNA; The flexible outer boundary of every cell that controls what enters and exits. Made of a phospholipid bilayer, it acts as a selective barrier maintaining the cell's internal environment.: Deoxyribonucleic acid — the molecule that carries genetic instructions for the development and function of all living organisms. It is stored in the nucleus and organised into 23 pairs of chromosomes in humans.
