3. 03

   Filamentous fungi have thread-like structures called hyphae, which help them absorb nutrients from their environment.

4. 04

   3D printing filaments are materials used to create objects layer by layer. Common types include PLA, ABS, and PETG.

5. 05

   Muscle fibers contain filaments called actin and myosin, which slide past each other to enable muscle contraction.

6. 06

   Filamentous algae are simple plants that form long chains or threads, often found in freshwater environments.

7. 07

   Filamentous bacteria like Streptomyces produce antibiotics and have a thread-like appearance.

8. 08

   Filamentous clouds, also known as cirrus clouds, are thin and wispy, often indicating fair weather.

Filaments in Technology

Filaments have revolutionized various technological fields, from lighting to 3D printing. Let's dive into some intriguing facts about their applications.

9. 09

   Incandescent light bulbs use a filament that heats up and emits light when an electric current passes through it.

10. 10
