I hypothesized that as the number of layers of wash-in-walk fabric increased in between the spinach and light source‚ which is giving the spinach less access to light‚ would result in a smaller depletion of carbon dioxide compared to the runs with less wash-in-walk fabric in between the light source and the

xylem - running through the petiole - transport water and mineral ions from the roots phloem - transporting sugars and other small organic molecules to different parts of the plant. epidermis - function is to protect the inner layers of cells - is a close fitting layer on both the top and bottom of the leaf. epidermal cells sometimes secrete a waxy cuticle - reduces evaporation from cells. lower epidermis there are stomata each stoma is surrounded by guard cells - can open/close the space between

semiconductor materials natural choices for electronic device investigations. Semiconductor materials are found in column IV and neighboring columns of the periodic table (Table 1-1).The column IV semiconductors‚ sil- icon and germanium‚ are called elemental semiconductors because they are composed of single species of atoms. In addition to the elemental materials‚ compounds of column III and column V atoms‚ as well as certain combina- tions from II and VI‚ and from IV‚ make up the compound semiconductors
