photosynthetic
C2Pronunciation
UK

US

Description
- Using sunlight to make food
- Connected with photosynthesis
- Sun-powered
Imagine plants as tiny chefs! They do not go grocery shopping. Instead, they use a process called photosynthesis to make their own food. Anything photosynthetic is connected with this ability, a bit like calling something "solar-powered" because it uses the sun for energy. Plants are photosynthetic, and some algae and bacteria are too. That is how they turn light into food. You would not describe a lion as photosynthetic, but you would talk about the photosynthetic rate of a rainforest.
The word photosynthetic describes organisms or processes that involve *photosynthesis*, the remarkable process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of sugars (food). It's essentially how these organisms "eat"—they don't ingest food like animals do.
The word itself breaks down into parts: "photo" means light, and the rest comes from a word meaning to put together. So, photosynthetic literally carries the idea of "putting together with light."
You'll most often encounter this term in biology or environmental science contexts. For example, scientists might study the photosynthetic efficiency of different plant species, or discuss how photosynthetic organisms contribute to Earth's oxygen supply. It can also be used more broadly to describe anything related to this process—a photosynthetic pigment like chlorophyll, or a photosynthetic reaction.
While you wouldn't say your breakfast is photosynthetic (unless it contains photosynthetic organisms like spinach!), understanding the term unlocks a key piece of how life on Earth thrives. It's the foundation of most food chains and a vital part of our planet's ecosystem. So, next time you see a lush green plant, remember it's a tiny, sun-powered food factory—beautifully photosynthetic at work!
Examples
- 1
Plant cells
Most plants need sunlight because their photosynthetic cells use it to make food.
- 2
Algae
Algae are photosynthetic organisms, so they can grow quickly in bright water.
- 3
Bacteria
Scientists found photosynthetic bacteria living near the surface of the lake.
- 4
Crop stress
Drought can lower a crop's photosynthetic activity, even when the leaves still look green.
