Conversation

Did you know that the outer layer of a cork tree is called phellem?

Really? I always thought cork was just cork.

It's interesting how phellem protects the tree and helps it retain moisture.

That makes sense! Nature has some amazing ways of adapting.

Root Explanation

Phellem is derived from the Greek word "phellos" (meaning cork). It refers to the outer layer of bark in plants, particularly in cork oaks, which is known for its insulating and protective properties.

Memory Tip

Think of 'cork' ('phellos') to remember that 'phellem' refers to the protective outer layer of bark, much like how cork protects bottles.
