Photosynthese
🌿 What exactly is die Photosynthese?
Die Photosynthese (photosynthesis) is a fundamental biochemical process carried out by plants, algae, and some bacteria. It uses light energy (usually sunlight) to convert low-energy inorganic substances – mainly carbon dioxide (CO₂) and water (H₂O) – into high-energy organic compounds (primarily glucose) and oxygen (O₂). This process is the foundation for almost all life on Earth, providing food and oxygen.
The German word is always feminine, so it's always die Photosynthese.
Article rules for der, die, and das
-e/-ee → almost always feminine.
There are many -e nouns, many of which are feminine, but there are also some important exceptions.
🧐 Grammar Focus: Declining die Photosynthese
The noun Photosynthese is feminine. It is mostly used only in the singular. The plural (die Photosynthesen) is very uncommon and used at most in specific scientific contexts to describe different types or mechanisms of photosynthesis.
| Case | Article | Noun |
|---|---|---|
| Nominative (Subject) | die | Photosynthese |
| Genitive (Possessive) | der | Photosynthese |
| Dative (Indirect Object) | der | Photosynthese |
| Accusative (Direct Object) | die | Photosynthese |
📝 Example Sentences
- Die Photosynthese ist für das Überleben der meisten Pflanzen unerlässlich. (Photosynthesis is essential for the survival of most plants.)
- Ohne Photosynthese gäbe es keinen Sauerstoff in unserer Atmosphäre. (Without photosynthesis, there would be no oxygen in our atmosphere.)
- Im Biologieunterricht lernen wir die Details der Photosynthese. (In biology class, we learn the details of photosynthesis.)
- Pflanzen nutzen die Sonnenenergie mittels der Photosynthese. (Plants use solar energy through photosynthesis.)
💡 How to Use die Photosynthese
The term Photosynthese is used almost exclusively in biological and scientific contexts. It describes the specific process of energy conversion by plants and other organisms.
- Biologie & Botanik (Biology & Botany): Main field of application for describing plant metabolism.
- Ökologie (Ecology): Important for understanding ecosystems, carbon cycles, and oxygen production.
- Bildung (Education): A central topic in biology lessons.
One often speaks of the Produkte der Photosynthese (products of photosynthesis - glucose and oxygen) or the Voraussetzungen für die Photosynthese (requirements for photosynthesis - Licht (light), Wasser (water), CO₂).
🧠 Mnemonics for die Photosynthese
For the article 'die': Think of 'the' Energy (die Energie) or 'the' Synthesis itself. Both 'energy' and 'synthesis' feel inherently linked to the process, and many German nouns ending in '-e' or '-is' are feminine ('die'). So, it's die Photosynthese.
For the meaning: Break it down: 'Photo' relates to light (like 'photography'). 'Synthesis' means putting things together. So, Photosynthese is 'putting things together using light' – which is exactly what plants do with CO₂, water, and sunlight to create energy (glucose).

Synonyms & Related Terms
- Assimilation (bei Pflanzen): Often used synonymously, generally describes the building up of the body's own substances. Photosynthesis is a specific type of assimilation.
- Kohlenstoffdioxid-Assimilation: More precise term for part of the process (carbon dioxide assimilation).
- (No direct, common single-word synonyms)
⚠️ Similar Words
- Chemosynthese (Chemosynthesis): A similar process, but energy is obtained from chemical reactions instead of light (e.g., in certain bacteria).
- Photolyse (Photolysis): The splitting of chemical compounds by light (e.g., the splitting of water as part of photosynthesis).
😂 A Little Plant Joke
Warum können Pflanzen keine Geheimnisse für sich behalten?
Weil sie ständig Photosynthese betreiben – sie „lichten“ alles ab! 😉
(Why can't plants keep secrets?
Because they are constantly performing photosynthesis - they 'bring everything to light' / 'photograph' everything! - A pun on 'ablichten' meaning to photograph or expose.)
📜 A Poem of Light
Im grünen Blatt, ein Wunder wirkt,
Die Photosynthese, unbezirkt.
Aus Licht und Luft, aus Wasser klar,
Wird Zucker süß und Sauerstoff, fürwahr.
Die Sonne schenkt die Energie,
So lebt die Pflanze, dank Magie.
(In the green leaf, a miracle works,
Photosynthesis, undisturbed.
From light and air, from water clear,
Sweet sugar and oxygen appear.
The sun provides the energy,
Thus lives the plant, thanks to magic.)
❓ What Am I?
Ich nutze Licht, doch hab kein Aug'.
Ich schaff' aus Luft 'nen süßen Hauch.
Ich geb' euch Luft zum Atmen frei,
bin in den Pflanzen mit dabei.
Was bin ich?(Auflösung: die Photosynthese)
(I use light, but have no eye.
I create a sweet breath from air.
I give you air to breathe freely,
I am present within the plants.
What am I?
Answer: Photosynthesis / die Photosynthese)
🧩 Other Interesting Facts
- Wortherkunft (Etymology): The word comes from Greek: φῶς (phos) = 'light' and σύνθεσις (synthesis) = 'composition'.
- Bedeutung für das Klima (Importance for Climate): Photosynthesis plays a crucial role in the global carbon cycle and influences the climate by absorbing CO₂.
- Chlorophyll: The green pigment in plants (chlorophyll) is essential for absorbing light energy during photosynthesis.
📝 Summary: is it der, die or das Photosynthese?
The German word Photosynthese is always feminine. The correct article is die. Remember: die Photosynthese.
