BIOLOGY LESSON NOTE FOR THIRD TERM SS2

Below are the Excerpts (Samples) of the 2023 Complete Biology Lesson Notes for SS2 Third Term

WEEK 1: EXCRETION AND EXCRETORY SYSTEM

CONTENT

  • Excretion
  • Types of Excretory structures and Taste
  • Excretory Structures in some Organisms

EXCRETION

Excretion is the process by which metabolic waste products are removed from the body of all living things. Excretion is different from egestion which is the removal of solid waste (undigested food substances i.e.faeces) through the anus. Excretion is necessary for the following reasons:

  • To avoid or prevent any harm that would be caused by any excretory product.
  • Some excretory products are poisonous to the body and should be removed.
  • To maintain water balance in the body (homeostasis).
  • To avoid interference of waste products with normal metabolic activities in the body.

EXCRETORY STRUCTURES AND WASTE IN ORGANISMS

Organism Excretory Structure Excretory Waste Product    
Protozoa Contractile vacuole C02, ammonia and water
Flatworm Flame cells C02, ammonia and water
Earthworm Nephridia C02, ammonia and water
Crustacean Green glands C02, ammonia and water
Insect Malpighian tubules C02, ammonia and uric acid
Fish Kidney C02, ammonia and water
Amphibian(toad) Kidney H20 and salt
Reptiles Kidney H20 and salt
Birds Kidney and lungs C02 and water vapour
Mammals Kidney, lungs, skin and liver C02, water, urea
Flowering plants Stomata, lenticels and leaves H20, C02, 02. tannins, gum, alkaloids, oil and latex

 EVALUATION

  1. List five excretory structures adapted to aquatic habitat
  2. Mention four excretory waste in plants

TYPES OF EXCRETORY SYSTEMS

CONTRACTILE VACUOLE IN PROTOZOA

Contractile vacuole is a simple structure found in the cell of fresh water protozoa. Water constantly enters the cell of a protozoan through the selectively permeable membrane because the cell is hypertonic to its environment. As water enters the cell, a contractile vacuole is formed which collects the water and expands, when it reaches the maximum size, it contracts and discharges the water through a temporary break in the cell membrane at interval. Excretion of carbon dioxide and ammonia is by diffusion through the cell membrane

FLAME CELL IN FLATWORMS

The excretory system consists of two longitudinal canals with branched tubules which end in flame cells. The flame cell has a large hollow called the cell lumen with bunch of flagella hung on it. Waste product from the surrounding cells enters the flame cells. The flagella help to propel the fluid into the tubules. The fluid passes into the exterior through a narrow tube called duct.

NEPHRIDIUM IN EARTHWORM

A pair of nephridia is found on each segment of the earthworm except the three and the last. Each nephridium consists of a ciliated funnel, nephrostome which leads into a long coiled tube (narrow and middle ciliated tubes, wide non-ciliated tubes and muscular tube). The tube opens to the exterior as nephriodiophore (excretory pore). Waste product mainly urea is absorbed from blood capillaries surrounding the nephridia. The fluid containing the waste through the long tube of the nephridia, salt and other useful substances are reabsorbed through the wall of the tube. The unabsorbed substances and water gather in the muscular tube and discharge to the exterior through the excretory pore.

EVALUATION

  1. How are excretory products removed in amoeba and earthworm?
  2. Describe the excretory structure in flatworm.

MALPIGHIAN TUBULE IN INSECT

Malpighian tubules are found between the midgut (small intestine) and the hindgut (large intestine). One end opens into the gut while the other end closed freely floats in the haemocoel. Nitrogenous waste and water in the haemocoel are absorbed at the distal close end into the tubule. The waste is converted into uric acid as it passes along the malpighian tubule towards the gut. A lot of water is also reabsorbed so that by the time the uric acid reaches the proximal end, it is changed to solid crystals. More water is reabsorbed in the rectum therefore concentrated urine leaves the body as almost dried solid.

GENERAL EVALUATION

  1. Define excretion.
  2. Explain the necessity for an excretory system in animals.
  3. Describe the mechanism of excretion in insects.
  4. List five excretory product in plants.
  5. Differentiate between excretion and egestion.
