Question- 1 :
Why is amoeba an irregular organism ?

Question- 2 :
What is contractile vacuole ?
Answer- 2 :
A contractile vacuole is a specialized type of vacuole in eukaryotic cells, particularly protozoa and certain unicellular algae. It is involved in osmoregulation. The contractile vacuole contracts to expel water out of the cell.

Question. 3 :
State the functions in Amoeba ?
Answer. 3 :
Amoeba is a unicellular organism. A contractile vacuole works just the same as the name suggests, in that it expands and contracts. The function of the contractile vacuole is to pump water out of the cell through a process called osmoregulation, the regulation of osmotic pressure.

➊ Why is amoeba an irregular organism ?
Ans - Amoeba does not have any regular shape because the exterior cover of the body is the cell membrane where nucleus us centrally present surrounded by cyptoplasm.
➋ What is contractile vacuole? State its function in amoeba.
Ans - Contractile vacuole in the amoeba collects the excess water in it's body. Ammonia is at times expelled along with the water out of the contractile vacuole as ammonia is soluble in water. The contractile vacuole in amoeba shrinks when excess water excreted surroundings and expands when it takes in water.
➌ List 5 uses of bacteria and fungi in our lives.

➛ They help in the formation of manure and compost.
➛ Certain bacteria help in curing and tanning I'd animals hides to make leather.
