Document Summary

At the base of every leaf is an axillary bud helps determine what type of leaf it is (entire leaf or leaflets): leaflets do not have axillary buds. Nodes (portions of stem that leaves grow off) are also products of the terminal bud: leaves that are whole (not cut into pieces or leaflets) are referred to as entire. The blades are where photosynthesis occurs: not all leaves have petioles (thin strands connecting a blade to the stem). When the petiole is not present, the leaf is called sessile: they can give rise to another shoot vegetative or reproductive, leaves are initiated by the activity of the sam (terminal bud). There are two broad leaf types (based on the structural form of the blade): simple blade that is not divided into leaflets. No divisions of the leaf that penetrate to the petioles (lobes may be present not divided): compound where the blade is divided into leaflets.
