Pine leafs under the microscope reveal a complex structure that is essential to the pine tree. Here is a breakdown:
- Fibrovascular bundles, act like blood vessels in the human body. Part of this bundle is called the xylem which moves water and minerals to the plant, and the other is called phloem which moves the nutrients.
- Resin ducts, hold the resin of the pine tree which is used as a defense against animals and insects.
- Chlorophyll cells are called chlorenchyma, they protect the pine tree from stresses like rain and strong wind.
- Stoma are special pores that allow gases to exchange within the cell to allow the pine tree to "breathe".
