What is a simple leaf?

A simple leaf blade is undivided as shown on the left (though the margins may be toothed or even lobed). The blade of a compound leaf is divided into several leaflets as shown on the right. There are no buds at the base of each leaflet.

Furthermore, what is the lamina of a leaf?

leaf structure. In leaf. …a broad expanded blade (the lamina), attached to the plant stem by a stalklike petiole. Leaves are, however, quite diverse in size, shape, and various other characteristics, including the nature of the blade margin and the type of venation (arrangement of veins).

Do all leaves have petioles?

Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves. The arrangement of veins in a leaf is called the venation pattern; monocots have parallel venation, while dicots have reticulate venation.

What is a petiole and what function does it serve?

If you've eaten a celery stalk, you've eaten a petiole, the part of some plants that connects the blade of a leaf to its stem. In terms of their function, petioles play an important part in photosynthesis. They are also responsible for the dramatic way deciduous trees lose their leaves in the fall.
