Leaf Drop #2
A leaf is a plant organ and is made up of a collection of tissues in a regular organisation. The major tissue systems present are:
1.The epidermis that covers the upper and lower surfaces
2.The mesophyll inside the leaf that is rich in chloroplasts (also called chlorenchyma)
3.The arrangement of veins (the vascular tissue)
These three tissue systems typically form a regular organisation at the cellular scale.
