The key word here is “synthesized”. Polymers are long chains of monomers,
All living cells and many of the tiny organelles internal to cells are bounded by thin membranes. These membranes are composed primarily of phospholipids and proteins and are typically described as phospholipid bi-layers.
When plants, bugs ect decay they give nutrients to the soil to help it stay healthy and fertile.
Glucose is the monomer of starch (a polymer).
Hope this helps! :)
