Stuffed Animals. Thereâs TONS of stuffed Disney animals and friends on eBay. One of the most expensive is this Genie doll, which is listed for $1,000. I know I have some of these somewhere, but mine are definitely more, ah, âwell-lovedâ than this one.
1 spongy mesophyll The plant tissue in a leaf which has loosely packed cells and air spaces between them to allow gas exchange. 2  stomata Tiny holes in the epidermis (skin) of a leaf-usually on the undersides of leaves. 3  They control water loss and gas exchange by opening and closing.
Detailed Description of the Experiment. Leaf stomata are the principal means of gas exchange in vascular plants. Stomata are small pores, typically on the undersides of leaves, that are opened or closed under the control of a pair of banana-shaped cells called guard cells (see figure above). When open, stomata allow CO2 to enter the leaf for synthesis of glucose, and also allow for water, H2O, and free oxygen, O2, to escape.
