Illustrations show how genetic instructions carried on DNA are transcribed into RNA, leading to the production of specific enzymes that control the thousands of biochemical processes going on in living cells.
Illustrates the mechanisms of photosynthesis and cellular respiration. It introduces ATP, the universal energy carrier molecules that supplies energy hungry reactions, and shows the structure and function of Chloroplasts and Mitochondria, energy transforming organelles.

A good way to observe reproducing cells is to start with a sparse population of protozoa. A sample of water from a shallow pond, gutter, flowerpot, or ditch is a good source. Examine the sample through a microscope and look for microbes, specifically for dividing microbes.

Here students become acquainted with the properties of the plasma membrane, how it governs the kinds of molecules that go in and out of cells, and how cells feed by engulfing (phagocytosis) and drink in fluids by pinocytosis.
