A simple leaf has an undivided blade. However, the leaf may be dissected to form lobes, but the gaps between lobes do not reach to the main vein. A compound leaf has a fully subdivided blade, each leaflet of the blade being separated along a main or secondary vein. The leaflets may have petiolules and stipels, the equivalents of the petioles ...
English: The fine scale structure of a leaf featuring the major tissues; the upper and lower epithelia (and associated cuticles), the palisade and spongy mesophyll and the guard cells of the stoma. Vascular tissue (veins) is not shown. Key plant cell organelles (the cell wall, nucleus, chloroplasts, vacuole and cytoplasm) are also shown.
English: The medium scale structure of a leaf featuring the major tissues; the upper and lower epithelia (and associated cuticles), the palisade and spongy mesophyll and the guard cells of the stoma. Vascular tissue (veins), made up of xylem, phloem and sheath cells, and example trichromes are also shown.
English: A simple diagram of a plant leaf cell, labelled with numbers. It shows the cytoplasm, nucleus, cell membrane, cell wall, mitochondria, permanent vacuole, and chloroplasts. Note going down the left the numbers are not sequential, this is to match the numbering on others in the series. Cytoplasm; Nucleus; Cell membrane; Mitochondrion ...

Diagram of fine scale leaf internal anatomy. The epidermal tissue includes several differentiated cell types: epidermal cells, guard cells, subsidiary cells, and epidermal hairs . The epidermal cells are the most numerous, largest, and least specialized. These are typically more elongated in the leaves of monocots than in those of dicots.
A wonderful diagram, assuming the content is accurate. Rwxrwxrwx 22:42, 28 April 2011 (UTC) Support but you really should drop the number of required votes to 4. Adam Cuerden 08:23, 3 May 2011 (UTC) Promoted File:Leaf Tissue Structure.svg--Makeemlighter 01:45, 4 May 2011 (UTC)
Diagram of the internal structure of a leaf. Palisade cell, or palisade mesophyll cell are plant cells located inside the mesophyll of most green leaves.They are vertically elongated and are stacked side by side, in contrast to the irregular and loosely arranged spongy mesophyll cells beneath them.
