S2 Biology
Module 2.1 – Digestion
Pupils will study the basic structure of
the human digestive system. They will learn about both the mechanical and
chemical breakdown of the nutrients in their food. They will be introduced to
the role of enzymes and carry out practical investigations.
Module 2.2– Heart and Circulation
Pupils will study the basic structure of
the human
Module 2.3– Cell Division
Pupils will learn about the complex
process of cell division. Chromosomes will be
described in detail, explaining the way genetic information is stored on them
in units called genes that are made of DNA. The need for nuclear division to
take place before cell division in the cell cycle is then explained and the
steps in this nuclear division, mitosis, are then covered.
Module 2.4– Photosynthesis
and Respiration
Pupils will learn about the basic
biochemical reactions of photosynthesis and respiration. They will be
introduced to the word equations for each process and begin to learn the
significance of each of these reactions to all living organisms.
