photosynthesis
The biochemical process by which green plants and some other organisms use light energy to produce nutrients (glucose) and oxygen from carbon dioxide and water.
Ohne die Photosynthese der Pflanzen gäbe es keinen Sauerstoff in unserer Atmosphäre.
Without the photosynthesis of plants, there would be no oxygen in our atmosphere.
The word comes from Greek. 'Photo-' means 'light' and 'Synthese' means 'synthesis' or 'combination'. Literally, it is therefore a 'combination with light', which describes the process well.
Im Biologieunterricht lernen wir die Details der Photosynthese.
In biology class, we learn the details of photosynthesis.
'Photosynthese' (photosynthesis) is a technical term from biology and chemistry. In normal everyday life, the word is rarely used unless you are talking about scientific topics.
Für ihre Präsentation über Pflanzen musste sie die Photosynthese erklären.
For her presentation about plants, she had to explain photosynthesis.
The verb most commonly used with 'Photosynthese' (photosynthesis) is 'betreiben' (to carry out). You say: 'Pflanzen betreiben Photosynthese' (plants carry out photosynthesis).
Grüne Algen betreiben ebenfalls Photosynthese und produzieren dabei Sauerstoff.
Green algae also carry out photosynthesis and produce oxygen in the process.
