A leaf insect - walking leaves - popular names of the Phylliidae family.

Leaf insects use camouflage to take on the appearance of a leaf. They do this so accurately that predators often aren't able to distinguish them from real leaves. In some species the edge of the leaf insect's body even has the appearance of bite marks. To further confuse predators, when the leaf insect walks.

Angiosperm Leaf: Palisade Mesophyll in Nymphea

cross section: Nymphea leaf common name: Waterlily magnification: 400x Both the upper (adaxial) and lower (abaxial) epidermis are uniseriate and contain chloroplasts. The air exposed adaxial epidermis is well cutinized and contain numerous stomata that open into large substomatal air chambers. The submerged abaxial epidermis has a very thin cuticle and lacks stomata. Dark staining slime glands are present on the abaxial surface. Deep to the upper epidermis are several layers of tightly packed palisade mesophyll, the chief photosynthetic tissue of the leaf. Most of the leaf interior is occupied by a deeper zone of spongy mesophyll with large air spaces. Large red staining branched astroscleroids are abundant throughout the mesophyll. cross section: Nymphea leaf common name: Waterlily magnification: 400x Both the upper (adaxial) and lower (abaxial) epidermis are uniseriate and contain chloroplasts.

Angiosperm Morphology: Bulliform Cells in Zea Leaf

cross section:Zea leaf common name: corn magnification: 400x The iso-bilateral leaf of Zea is typical of most monocots. Both upper and lower epidermis are uniseriate and well cutinized. Within the upper, or adaxial, epidermis, large white bulliform cells shrink, allowing the leaf to roll during drought. Stomata are present on both surfaces with guard cells perched above small round substomatal chambers. As with most monocots the mesophyll is unspecialized, being composed of compactly arranged somewhat round chlorenchyma cells. Numerous small and occasionally large vascular bundles are arranged in parallel series along the length of the leaf. The vascular bundles are collateral and closed with xylem of vessels and tracheids towards the adaxial surface and phloem of sieve tubes and companion cells towards the abaxial surface. Cambium is not present. Within each bundle a xylem of two oval metaxylem and a single large protoxylem cavity can be seen. Each vascular bundle is wraped by a bundle sheath of thin walled parenchyma cells. Larger bundles are supported towards both surfaces by masses of sclerenchyma that interrupt the mesophyll to form a patchy hypodermis. cross section:Zea leaf common name: corn magnification: 400x The iso-bilateral leaf of Zea is typical of most monocots.
