Differentiate between micronucleus and macronucleus of ciliates Or What are functions of micronucleus and macronucleus? or Describe the nuclei of ciliates.

Ciliates have two kinds of nuclei, one or more small diploid micronuclei that function in sexual process, and a large, polyploid macronucleus that controls cell metabolism and growth.

Write example of parasitic Apicomplexans. Give symptoms of malaria or Write a note on Plasmodium causing disease or Draw the life cycle of Plasmodium.

Plasmodium is the apicomplexan that causes malaria, Here is the life cycle of Plasmodium:

  •  It enters human blood through the bite of an infected female Anopheles mosquito.
  • Plasmodium first enters liver cells and then red blood cells, where it multiplies.
  • When each infected red blood cell bursts, many new parasites are released.
  • The released parasites (merozoites) infect new red blood cells, and the process is repeated.
  • The simultaneous bursting of millions of red cells causes the symptoms of malaria a chill, followed by high fever caused by toxic substances that are released and affect other organs of the body.
  • Ultimately sexual forms i.e., gametocytes are formed which are taken up. when female Anopheles mosquito sucks the blood of malaria patients.
  • Rest of the life cycle of Plasmodium is completed in mosquito until spindle. shaped parasites (sporozoites) are formed which stay in the salivary gland.
