What is the horsetail made of?

Horsetails are made of silica, a compound that gives them their rough, abrasive texture. This is the same material found in glass and sand!

Here's a breakdown:

* Cell Walls: Horsetail cells have thick cell walls reinforced with silica. This makes them strong and resistant to bending.

* Silica Deposits: The silica is deposited in the form of tiny, sharp particles. This gives horsetails their distinctive rough feel.

Why is silica important?

* Structural Support: The silica provides rigidity, helping the plant stand upright and withstand strong winds.

* Protection: The abrasive texture deters herbivores from eating them.

So, while horsetails might look like a simple plant, they're actually quite sophisticated, utilizing silica to ensure their survival!
