Introduction: Robert Hooke was the first one to use the term ‘cell’. A cell is the structural and functional unit of all living organisms. Cells exist in all shapes and sizes. They differ in the kind of function they perform for the organism.

Answer to Problem 1A
The plasma membrane is a structure that surrounds a cell and helps control what enters and exits the cell.
Explanation of Solution
All cells have a special membrane called plasma membrane that acts as a thin flexible boundary between a cell and its watery environment. It controls what enters and leave the cell. The cells of our skin and that of a plant stem, all have a plasma membrane. It also helps in maintaining homeostasis in an organism. Plasma membranes are selectively permeable as they allow only certain substances to pass through while keeping others out. All prokaryotes and eukaryotes have plasma membrane.
The nucleus is like a manger of the cell. It controls the activities of the cell. It stores the genetic material of the cell which contains information for protein synthesis. Nucleus does not surround the cell but is present inside a cell. Hence this is not the correct word.

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. Plasmodium falciparumarrow_forward
