Glucose (C₆H₁₂O₆), also called dextrose, is one of a group of carbohydrates known as simple sugars (monosaccharides). It is found in fruits and honey and is the major free sugar circulating in the blood of higher animals. It is the most important source of energy for cellular respiration. Glucose is stored as a polymer, in plants as starch and in animals as glycogen.

The cell theory states that all living things are made of cells, cells are the basic units of structure and function of living things, and that all cells come from other cells. Since viruses are not made of cells, and do not use cells in any of their processes, they are not related to the cell theory.

Chlorophyll was first isolated and named by Joseph Bienaimé Caventou and Pierre Joseph Pelletier in 1817. It is a chemical found in the chloroplasts of plants that allows the plant to absorb light. Energy from the light is used in photosynthesis to make glucose.

Beriberi is a disease caused by a vitamin B1 (thiamine) deficiency. There are two types of the disease: wet beriberi and dry beriberi. Wet beriberi affects the heart and circulatory system. In extreme cases, wet beriberi can cause heart failure. Dry beriberi damages the nerves and can lead to a loss of muscle strength and eventually, muscle paralysis.
