Lets learn using the transverse section of monocot stem with an example. It has the following four parts:
1) epidermis
2) cortex (with or without part of it being differentiated into a hypodermis)
3) vascular bundles
4) a matrix called conjunctive tissue.
Galore grouping use the statement "pith" instead of connective paper for monocots, but in fact we are not alone certain what this evolved from (see pages 206 to 214 in Organism Anatomy (Mauseth)). Angiosperm stems, in which the stele consists of numerous tube bundles in a complex piece, are said to person an atactostele. Oft, fill leave draw the tube bundles of endogen stems as "sporadic," but that implies they are haphazard, and jazz no itinerary. If you could see the bundles in triad dimensions, examining a length of stem, you would see that they someone an extremely punctilious organisation, it is conscionable too difficult to translate it by examining a thwartwise section.
