GCSE Combined Science · key term
A sub-cellular structure where photosynthesis takes place, containing chlorophyll to absorb light energy.
Used by AQA and Edexcel
Specification 4.1.1.2, 4.4.1.1 · Paper 1
Revise: Sub-cellular structures and their functionsPlant cells also contain these structures, but often have chloroplasts and a permanent vacuole as well. Plant and algal cells have a cellulose cell wall.
A structure within a plant cell where photosynthesis takes place.
Paper 1, Paper 2
An organelle containing chlorophyll that absorbs light for photosynthesis.
Revise: Cell Structures and Specialised CellsChloroplasts are the sites of photosynthesis. They contain the green pigment chlorophyll, which absorbs the light needed for photosynthesis. This process makes food for the plant.
Link each named structure to its function: for example, chloroplasts carry out photosynthesis, rather than simply making a cell green.
Remember the qualifiers: most animal cells have the listed structures, and not all plant cells contain chloroplasts.
When explaining why photosynthesis is endothermic, state that energy is transferred from the environment to the chloroplasts by light.
