Question 1
(a) State one function each of the following parts of the nephron:
(i) glomerulus;
Answer
- The primary function of a glomerulus is to filter blood passing through it.
- It removes waste products and excess fluid from the bloodstream and passes them into the nephron to be excreted as urine
(ii) Browman’s capsule;
Answer:
Collects the filtrate produced by the glomerulus, initiating the process of blood filtration and urine formation by allowing small molecules from the blood to pass through its walls while retaining larger molecules like blood cells and proteins.
(iii) proximal convoluted tubule;
Answer:
Selective reabsorption takes place. Glucose, amino acids, vitamins and water are reabsorbed at the proximal convoluted tubule into the blood vessels
(iv) distal convoluted tubule.
Answer:
The distal convoluted tubule selectively reabsorbs ions such as sodium, chloride and calcium from the tubular fluid, while potassium is secreted.
(b) Complete the table below.
Answer:
| Organism | Structure for excretion | Form in which waste is excreted by organism |
| Amoeba/Paramecium | Contractile vacuole | Gaseous/Liquid |
| Flatworm | Flame cell | Liquid |
| Earthworm | Nephridium/Nephridia | Liquid |
| Cockroach | Malpighian tubule | Solid |
| Human | Kidney/Skin/Lungs | Liquid |
| Plant (green) | Stomata pore | Gaseous |
