cross section: Sambucus stem magnification: 400x Berkshire Community College Bioscience Image Library A one-year stem of Sambucus demonstrates the differentiation of the upper cortex in tissues of the periderm. During the first year of growth the epidermis is stretched laterally by the expansion of secondary xylem, phloem and cambium. The epidermis is replaced by a protective secondary zone of cork rich periderm. Continual growth of the periderm keeps up with that of underling tissues allowing it to replace the functions of the degrading epidermis. The outermost layer of periderm consists of layers of cork cells, the phellem, which produce the waterproofing substance suberin. Cork cells are dead at maturity. Deep to the phellem is a layer of living green stained cork cambium or phellogen and just beneath that layers of cork parenchyma or phelloderm. Many cells in the periderm contain dark staining tannins. In certain areas the cork cambium over produces cork cells, resulting in the formation of ridges and deep cracks in the periderm. These deep fissures, or lenticels, permit gas exchange with tissues under the periderm. Technical Questions:[email protected]

cross section: One year Quercus stem magnification: 400x Berkshire Community College Bioscience Image Library Due to meristematic activity the vascular bundles have expanded to form a cylinder consisting of a narrow outer ring of primary phloem, a middle single layered ring of vascular cambium and a deeper large ring of primary xylem. The phloem is overlaid by heavy continuous ring of sclerenchyma. Bulging into the pith are small masses of the first xylem consisting of small protoxylem cells overlaid by a few larger, heavier walled cells of metaxylem. Above this and extending to the cambium are columns of primary xylem divided by narrow rays, extending from the large parenchymatous pith to the phloem. Technical Questions:[email protected]

I covered botany during 2 blocks last year.. and I am finally getting around to posting our work! First, here is a list of the resources that I used:  Botany by Charles Kovacs The Plant, Vol. 1 by Gerbert Grohmann Botany - A Golden science guide (used in reference for drawings) Drawing from the Book…

My kids are budding scientists.  Nearly every afternoon you will find us carefully mixing household items, creating charts, or dissecting small bits of God’s creation.  From my four year old carefully putting paper clips onto a foil boat and watching them float to my 11 year old learning Greek and Latin roots describing plants, Apologia is hands down my favorite science curriculum. This post contains affiliate links. Presently, we are working through Apologia Botany and I am enjoying it just as much as the kids.   Why I Love Apologia   First, let me explain why I love Apologia Botany in general. The text is God centered.  God is given the glory for His amazing creation and verses are often included. Experiments are plentiful.  Not only do they keep inquisitive minds satisfied, they are simple and usually require everyday household items. Accompanying notebooks are full of engaging reinforcement activities which would take me forever to put together on my own.  The notebooks come in two different levels, giving you options to choose what works best for your family. If you choose not to buy the accompanying notebooks, activities are still included with each lesson for different levels. The textbooks are engaging with […]
