To recognize:
The role of the nucleus in cellular activities
Introduction:
The nucleus controls different cellular
Most of the cells have only one nucleus that is uninucleate or monokaryotic cells, however, some animals have two nuclei in single cells it’s called binucleate for example Paramecium caudatum. Some animals have three nuclei in single cell they called as trinucleate cells for example, Paramecium Aurelia same like some animal cells has many nucleus it is called multinucleate cells example plasmodium in slime moulds. It is syncytium in animal cells and coenocytic in plant cells, a nucleus is absent in some mature cells like mammalian RBCs (red blood cells) and sieve tube cells. They are called nucleated cells. The term enucleate is used more commonly for cells from which nucleus has been removed.

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes. Which of the following Plasmodium species is most likely responsible for her severe symptoms? A. Plasmodium vivax B. Plasmodium ovale C. Plasmodium malariae D.
