Stem submerged dicot: Nymphaea

cross section: Nymphaea stem magnification: 100x The bulk of the stem consists of open airy aerenchyma with numerous large air chambers that aide in respiration and buoyancy The vascular bundles are surrounded by a starch containing endodermis in which the red staining casparian strip may occasionally be seen. A pericycle can be seen beneath the endodermis. Like my hydrophytes, xylem tissues are reduced while phloem tissue are well developed and, in lager bundles may form in two distinct patches. cross section: Nymphaea stem magnification: 100x The bulk of the stem consists of open airy aerenchyma with numerous large air chambers that aide in respiration and buoyancy The vascular bundles are surrounded by a starch containing endodermis in which the red staining casparian strip may occasionally be seen.

Angiosperm Leaf: Stomatal Pits in Nymphaea

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.
