Leaf

lēf | Noun

The most recognizable part of the cannabis plant and the primary location of photosynthesis and transpiration. There are two major types of leaves; fan leaves and sugar leaves. The fan leaves are the large leaves that contain very little trichomes. Differences in fan leaf size and width can indicate whether a plant is of the sativa, indica, or ruderalis variety. The sugar leaves are the small, trichome-covered leaves that surround the flower clusters and are typically trimmed off the plant after it has been harvested and dried.
