Q1: What is transportation in organisms?

Transportation is the process of carrying substances from one part of the organism to another. In animals: circulatory system transports blood, nutrients, oxygen and hormones. In plants: xylem transports water and mineral salts; phloem transports food.

Q2: Name the main components of blood.

Blood consists of: 1. Plasma: Liquid component carrying nutrients, waste and hormones 2. Red blood cells (RBC): Carry oxygen 3. White blood cells (WBC): Protect against infections 4. Platelets: Help in blood clotting

Q3: Define the term 'circulation' in the context of blood.

Circulation is the continuous flow of blood through the heart, arteries, capillaries and veins. Blood carries oxygen and nutrients to all cells and removes waste products. The heart acts as a pump to push blood through the circulatory system.

Q4: What is the function of arteries and veins?

Arteries: - Carry blood away from the heart - Blood in arteries is oxygenated (except pulmonary artery) - Have thick, muscular walls - Blood moves in pulses Veins: - Carry blood towards the heart - Blood in veins is deoxygenated (except pulmonary vein) - Have thin walls with valves - Blood flow is slow and steady

Q5: What is the structure and function of xylem in plants?

Xylem is a vascular tissue in plants composed of: - Tracheids and vessels: Conduct water - Fibres: Provide support - Parenchyma: Store food Function: Transports water and mineral salts from roots to all parts of the plant. Transport is unidirectional (upward only).

Q6: Describe the structure and function of phloem tissue.

Phloem consists of: - Sieve tubes: Conduct food - Companion cells: Assist sieve tubes - Fibres: Provide support - Parenchyma: Store food Function: Transports manufactured food (glucose) from leaves to all parts of the plant. Transport is bidirectional (up and down as needed).
