To Review:
The difference between hormones, enzymes, and vitamins.
Introduction:
The plant needs a variety of factor to carry out its physiological and general cellular activities. The hormones and enzymes help in providing the signals in the plants and the vitamins are one of the important nutrients.

Explanation of Solution
The hormones are the chemicals, which are secreted in a small quantity by the cells and help in the development of the plants. They act as a messenger for the cells and induce the activities essential for growth.
The enzymes are the chemical compounds, which bind to the substrate and help in the conversion of the substrate into the product. The enzyme is used to carry out a reaction, which cannot take place in the biological system.
The vitamins are the micronutrients and required in a small amount. The main function of the vitamin is to act as a coenzyme and activate several enzymes required for the reaction.
The hormones signal for growth and development. The enzyme help in carrying out the chemical conversions and the vitamins act as a coenzyme.

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.
