Miniunit Beta introduces students to cellular structure and function. Differences between eukaryote / prokaryote cells and plant / animal cells are emphasized. The chemical make-up, structure and function of cell organelles are presented in relation to their role in a whole organism. The concepts concerning cell function are: cell connections, movement of molecules across cell membranes, structure and function of enzymes. Human digestive and respiratory systems will be described to reinforce concepts learned in this miniunit.

Miniunit Gamma introduces the students to the cell cycle stressing cellular reproduction. Differences between eukaryote and prokaryote cells and viruses are emphasized. The various stages of fission, mitosis and meiosis are described. Emphasis on the end result of chromosomes number during mitosis and meiosis is emphasized to help the student in the next miniunit. Differences in plant and animal cycles are described. Human reproductive system will be described to reinforce concepts learned in this miniunit.

Miniunit Delta introduces students to basic genetic concepts. Building on cellular reproduction gene transfer in relation to monohybrid and dihybrid problems are presented to the students. Topics in gene expression include: complete and incomplete dominance, lethal genes, sex linked genes, multiple alleles, multiple genes, linked genes, crossing over. Gene function is presented through the following topics: replication, transcription and translation. Problems in human genetics will be described to reinforce concepts learned in this miniunit.

Miniunit Epsilon introduces the students to cellular energetics. Students are introduced to cellular metabolism - catabolism and anabolism. Emphasis is placed on cellular respiration (aerobic and anaerobic) and photosynthesis. The importance of these processes in relation to biological energy formation and production of carbon skeletons is stressed.

Miniunit Zeta introduces the students to basic ecological concepts. Building on energetics the importance of producers and consumers in an ecosystem are emphasized. Three areas stressed are: population and communities, ecosystems and biosphere.
