Critical point dried block of mature spruce wood block, demonstrating transverse, tangential and radial views of tracheids and vessels.
Critical point dried fractured cell from the tuber of potato (Solanum tuberosum), demonstrating thin cell walls starch grains (amyloplasts).
An insectivorous plant, the butterwort (Pinguicula vulgaris) has modified leaves which bear tiny granular trichomes which trap insects. The capitate head of the trichome then secretes protease enzymes to digest the insect parts.

Critical point dried epidermis of a xerophyte (cactus), demonstrating raised stomatal pores.
Trichomes and stomatal pores on the epidermal surface of a barley (Hordeum vulgare) leaf. Some very fine wax crystallites are also just visible on the surface of the leaf.
Critical point dried tip of barley (Hordeum vulgare) root, demonstrating root cap cells (calyptra) and slightly deformed (compressed) root hairs (Pili).
Critical point dried transverse fracture of a mature barley (Hordeum vulgare) root, demonstrating central stele and surrounding cortical cells. Root hairs (Pili) are also obvious.
Critical point dried transverse fracture of the stelar region of mature barley (Hordeum vulgare) root, demonstrating protoxylem pole cells, metaxylem vessels and endodermal sheath.
