Snap the bulb scale so that most of the epidermis of the convex side breaks in two (Figure 15.5). The epidermal layer will not break clean. Pull this layer back with forceps and place it on a drop of water inside down or inside up on a microscope slide. Lately it seems to me that...

Mechanical properties of onion epidermal tissue were measured using a miniature tensile stage mounted under a microscope. Epidermis peels were subjected to tensile tests while the deformation of the individual cells in the tissue was followed and recorded. Onion epidermal peels were found to produce a...
9.1F). The phytoplasmas like pleomorphic bodies of 110–970 nm were observed in the phloem tissues of infected plant under the transmission electron microscope (Samad et al., 2002). Based on 16S rDNA sequence identity and phylogenetic relationship, phytoplasma was identified to belong to ‘Ca. ...
(1)Under Low power of te microscope1.The rectangular cells of onion epidermis are seen.The regularly arranged components like cells have clear outline.In this case,the outlines are formed by rigid walls known as Cell Wall.2.A deeply coloured,round body is seen in side every cell.This is ...
squamosa was observed to enter the onion leaf by growing into anticlinal cell walls of the onion epidermis (Figure 2h,i). In several cases, germ tubes were observed to grow over stomata, presumably when they were closed, instead of growing through them. Likewise, germ tubes very often grew ...

Observations with the transmission electron microscope show that a complex suberin lamella encases each hypodermal cell but is absent from the epidermis. However, the outer tangential wall and radial walls of the epidermal cells are complex in that layers of different densities are present. Some of...
The endoplasmic reticulum (ER) of onion bulb scale epidermis cells consists of long, tubular strands lying deep in the cytoplasm which move quickly and a less mobile peripheral network of tubules and cisternae that change in position, shape and size but that also have immobile, fixed, sites (...
