Study Notes

Transportation in Animals and Plants

  • Organisms need food, water, and oxygen for survival
  • Animals and plants need to transport essential substances (food, oxygen) to different parts of the body and remove waste products.
  • Blood acts as a fluid to transport substances like digested food, oxygen, and waste, throughout the body.

Circulatory System

  • Blood is the fluid that flows in blood vessels and plays a vital role in transporting substances.
  • Blood contains plasma (a fluid) and different types of suspended cells.
  • Red blood cells (RBCs) contain haemoglobin which carries oxygen to all parts of the body.
  • White blood cells (WBCs) fight against germs that enter the body.
  • Platelets are essential for blood clotting.

Blood Vessels

  • Arteries carry oxygen-rich blood from the heart to all parts of the body. Their walls are thick and elastic, due to high pressure of the blood flow.
  • Veins carry carbon dioxide-rich blood from all parts of the body back to the heart having thin walls with valves to stop backflow.
  • Capillaries connect arteries and veins. Capillaries are extremely thin-walled tubes that allow exchange of materials between blood and tissues.

Heart

  • Heart is a pump that continuously transports blood to all parts of the body.
  • The heart has four chambers. Two upper chambers are called atria. Two lower chambers are ventricles.
  • The partition between the chambers (atria and ventricles) prevents the mixing of oxygenated and deoxygenated blood.

Blood Donation

  • Blood donation is vital for saving lives.
  • It involves the safe donation of blood to those in need. -Stored in blood banks.

Excretion in Animals

  • Excretion is necessary to remove waste products from the body which can be toxic. Waste substances are removed in liquid or gaseous form to maintain the balance of fluids.
  • Different animals have different ways to excrete waste like uric acid in semi-solid form in birds, insects, reptiles and humans urea in liquid.
  • The excretory system in humans consists of kidneys, ureters, urinary bladder and urethra, which filters waste and helps to remove urine.

Transportation in Plants

  • Plants absorb water and minerals through their roots.
  • Water and minerals are transported via xylem vessels from roots to stems and leaves.
  • Xylem transports water and minerals.
  • The food prepared by the leaves is transported through phloem vessels to different parts of the plant.

Transpiration

  • Transpiration is the process where plants lose water vapor through their leaves.
  • It helps plants absorb water and minerals by drawing water up through the plant to the stomata for release.
  • Transpiration cools the plant.
