Plant tissues imaged using the Wi-Fi DMD. (A) Cross-section of a corn stem in a prepared slide. (B) Longitudinal section of an onion root tip, stained to highlight cell nuclei (dark staining objects) in a prepared slide. (B.i) Root tip. (B.ii) A view of the root at some distance from the tip. Some cells contain two closely positioned dark-staining structures, consistent with mitotic activity in this rapidly growing tissue. (C) Red onion tunic. (C.i) Unpolarized light. (C.ii) Polarized light, revealing birefringent calcium oxalate crystals as bright objects in or on tunic cells.
