leaf to stem cuttings
examples of underground stems
Rhizomes(ginger), corms(onion), tubers(potato)
They arise from an organ other than the root-usually a stem sometimes a leaf
Adventitious root
Adventitious roots are numerous on
underground stems
Cells differentiate into different type of cells
Zone of maturation
Meristematic region, rapid mitosis of undifferentiated meristematic cells
Zone of cell division
allows the root to get deeper within the soil
Zone of elongation
Produce short cells(ray cells), mostly just storage parenchyma
Ray initials
example of Food-storage roots
sweet potatoes, beets, carrots
Modified for storage of starch
