This layer is formed by the bundle sheath cells, which contain the chloroplasts in which the Calvin cycle occurs. Note, too, that the mesophyll cells are not separated into well-defined palisade and spongy mesophyll layers, such as you observed in the Ligustrum leaf.. Fully label the drawing of the stereoscopic view of a portion of a leaf provided.

As a pup, the Rhodesian Ridgeback is active and exuberant, but he matures into a dog with moderate exercise needs. Give him a vigorous walk or game of fetch a couple of times a day, plus a chance to run in a safely fenced area a couple of times a week, and he'll be satisfied â at least in terms of physical exercise. The Rhodesian Ridgeback needs a high fence to keep him from escaping and roaming. 2  An underground electronic fence won't contain him. 3  Rhodesian Ridgebacks shed little, and you can keep them clean with a weekly brushing and a wipedown with a damp cloth.
