Science
Cells, Particles & Energy Basics
Cell structures, particle model and energy stores/transfers intro.
These ideas underpin biology, chemistry and physics through GCSE.
Cells
Animal vs plant organelles; specialised cells linked to function.
Particles
Solid/liquid/gas arrangement and movement; changes of state.
Energy
Stores (kinetic, thermal, chemical…) and transfers; conservation idea.
Why do plant cells have chloroplasts?
For photosynthesis – capturing light energy.
Practice
1. Name two organelles only in plant cells.
2. In which state are particles furthest apart?
