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.
In order to carry on cellular respiration, plant cells need oxygen and a means of disposing of carbon dioxide (just as animal cells do). Unlike animals, plants have no specialized organs for gas exchange (with the few inevitable exceptions!). The are several reasons they can get along without them: 1  Each part of the plant takes care of its own gas exchange needs. Although plants have an elaborate liquid transport system, it does not participate in gas transport. 2  Roots, stems, and leaves respire at rates much lower than are characteristic of animals.
