GCSE AQA (9-1) Chemistry

Paper 1 - Content overview

All of these key ideas will be assessed as part of this qualification, through the subject
content.

life processes depend on molecules whose structure is related to their function
the fundamental units of living organisms are cells, which may be part of highly adapted structures, including tissues, organs and organ systems, enabling living processes to be performed effectively
living organisms may form populations of single species, communities of many species and ecosystems, interacting with each other, with the environment and with humans in many different ways
living organisms are interdependent and show adaptations to their environment
life on Earth is dependent on photosynthesis in which green plants and algae trap light from the Sun to fix carbon dioxide and combine it with hydrogen from water to make organic compounds and oxygen
organic compounds are used as fuels in cellular respiration to allow the other chemical reactions necessary for life
the chemicals in ecosystems are continually cycling through the natural world
the characteristics of a living organism are influenced by its genome and its interaction with the environment
evolution occurs by a process of natural selection and accounts both for biodiversity and how organisms are all related to varying degrees.

All of these key ideas will be assessed as part of this qualification, through the subject
