Biology Unit 2 - Photosynthesis

Students have already met in year 7 and 8 the ideas that plant cellls are adapted to their functions and that they make thier own food with the help of sunlight.

This unit will help them to develop their ideas further - they will look at plant cells and tissues in more detail finding out how the various structures allow the maximum exhange of substances in and out.  They will look at how we use our understanding of photosynthesis to manipulate the environment in which plants are grown and discussing the environmental impact of farming practices.

We will also learn how the plant’s transport system is dependent on environmental conditions to ensure that leaf cells are provided with the water and carbon dioxide that they need for photosynthesis.
