(e) The apparatusto record the rate of transpiration in a cut shoot. In xerophytes, the stomata are recessed because they are situated within a depression in the form of a cup (e.g., Nerium). Night-time transpirational water loss is most likely the consequence of having respiratory CO2 escape at sufficiently high rates through stomata. The water, warmed by the sun, turns into vapor (evaporates), and passes out through thousands of tiny pores (stomata) mostly on the underside of the leaf surface. This helps in protecting against the escaping water vapor from air currents thereby decreasing water loss from the leaf and hence decreasing transpiration. Mixed Berry. This is the palisade mesophyll, which has specialized for capturing incoming sunlight, rotating chloroplasts to the top of the leaf and then allowing them to regenerate by cycling them toward the leaf's center.
