GCSE Biology · key term
A green pigment in chloroplasts that absorbs light energy for photosynthesis.
Used by AQA, Edexcel and OCR
Specification 4.4.1.1, 4.4.1.2 · Paper 1
The green pigment in chloroplasts that absorbs light.
Revise: Photosynthesis ReactionThe process takes place in chloroplasts, which contain chlorophyll that absorbs light.
The green pigment in chloroplasts that absorbs light energy for photosynthesis.
Specification 6.2 · Paper 2
A green pigment that absorbs light energy for photosynthesis.
Revise: Photosynthesis ReactionIn photosynthetic cells, chlorophyll absorbs the light, allowing carbon dioxide and water to react. In plants, this takes place in chloroplasts; photosynthetic algae also contain chlorophyll.
Specification B1.4b, B1.4c · Paper 1 (Foundation), Paper 3 (Higher)
Revise: Process of photosynthesisLight and chlorophyll are therefore commonly written over the reaction arrow rather than on either side of the equation: they enable the process but are not listed as its reactants or products.
The green pigment in chloroplasts that absorbs light, transferring energy for photosynthesis.
Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Higher), Paper 4 (Higher)
A green pigment that absorbs light energy for photosynthesis.
Revise: Process of PhotosynthesisIn plants, chlorophyll absorbs the light energy needed for this process.
The green pigment in chloroplasts that absorbs light, transferring the energy needed for photosynthesis.
Link structure to function explicitly: chloroplasts contain chlorophyll, chlorophyll absorbs light, and the transferred energy enables photosynthesis.
Keep chloroplast and chlorophyll distinct: a chloroplast is a subcellular structure; chlorophyll is the green pigment within it.
Avoid describing light as a chemical reactant or as a substance that becomes glucose. Light transfers energy to chlorophyll.
