This sequence begins with the chlorophyll parenchyma, phloem, epidermis,
bundle sheath parenchyma, and, as the least digestible tissues, the xylem and sclerenchyma (HANNA et al.
In most Lychnophorinae species, the vascular bundles are attached to the epidermis on both faces through
bundle sheath extensions (Figs.
A set of microdissectors is used to dissect the
bundle sheath and isolate the nerve branches from the adjacent vessels (Figure 1).
Vascular bundles are lined in rows and parenchymatic
bundle sheath is around of vascular bundles.
Small and medium-sized veins are immersed in the mesophyll and present endodermis (
bundle sheath).
In both grass species the injury mainly occurred to the chlorenchyma, which radiates around the
bundle sheath. It was also possible to observe that the parenchymatic sheath was affected in the signal grass.
[11] by the distance in transverse section between the outer edges of the
bundle sheath cells, adjacent to the two metaxylem vessels.
Prof Karpinski and his team found that when light triggered a chemical reaction in one leaf cell, it kicked off a "cascade" of events and that this was immediately signalled to the rest of the plant via a specific type of cell called "
bundle sheath cell".
2) with 2 or 6 subsidiary cells around guard cells in Astrocaryum, 4 in Hexopetion (11-13); (ii) chlorenchyma with palisade cells composed of short cells in Hexopetion and of long cells in Astrocaryum (61-62); (iii) fibers of
bundle sheath extension (Fig.
The vascular bundles of C4 plants are surrounded by a group of cells called
bundle sheath cells.
[C.sub.4] plants have succeeded in eliminating photorespiration by splitting the reactions of photosynthesis between two types of cells, mesophyll cells (MC) and
bundle sheath cells (BSC) (Kranz anatomy).
