How it works

A chloroplast is a chlorophyll-containing plastid. It contains thylakoids and stroma, with some thylakoids organised into stacks called grana.

The electron micrograph shows a chloroplast from a control Arabidopsis seedling in a particular study. The original figure retains a 1 μm scale; it does not show a spruce chloroplast.

Evidence for this statement

Source-based explanation

From organelle structure you can explore photosystem II and a PsbA protein record. This connects concepts; it does not establish that the molecular record came from the pictured specimen.

Photosynthesis

Photosynthesis synthesises organic compounds, including carbohydrates, from carbon dioxide using light energy. Gene Ontology identifies it as the biological process GO:0015979.

Source-based explanation

Photosystem II

Photosystem II is a molecular complex associated with pigments and electron carriers. In chloroplasts and cyanobacteria it uses light to transfer electrons from water to plastoquinone.
