2 Shade Leaves Specialized Leaves Leaves in the shade receive less total light, thus tend to be thinner and have fewer hairs than leaves on the same tree exposed to direct light. Leaves of Arid Regions Many have thick, leathery leaves and few stomata. Some have succulent, water-retaining leaves, or dense, hairy coverings.
3 Specialized Leaves Tendrils Modified leaves that curl around more rigid objects helping the plant to climb or support weak stems. - Become coiled like a spring as they develop. When contact is made, the tip curls around the object, and the direction of the coil reverses.
4 Specialized Leaves Spines, Thorns, and Prickles Spines - Modified leaves designed to reduce water loss and protect from herbivory. Thorns - Modified stems arising in the axils of leaves of woody plants. Prickles - Outgrowths from the epidermis or cortex.

10 Autumnal Changes in Leaf Color Cholorplasts of mature leaves contain several groups of pigments. Chlorophylls - Green Carotenoids Yellows, oranges, browns Xanthophylls Pale Yellow - In fall, chlorophylls break down and other colors are revealed. Water soluble anthocyanins (red or blue) and betacyanins (red) may also be present in the vacuole.
11 Autumnal Changes in Leaf Color
12 Autumnal Changes in Leaf Color Three factors influence autumn leaf colorleaf pigments, length of night, and weather. The timing of color change and leaf fall are primarily regulated by the calendar, that is, the increasing length of night. None of the other environmental influencestemperature, rainfall, food supply, and so on-are as unvarying as the steadily increasing length of night during autumn. As days grow shorter, and nights grow longer and cooler, biochemical processes in the leaf begin to paint the landscape with Nature's autumn palette.

As days grow shorter, and nights grow longer and cooler, biochemical processes in the leaf begin to paint the landscape with Nature's autumn palette.
14 Abscission Deciduous plants drop their leaves seasonally. Occurs as a result of changes in an abscission zone near the base of the petiole of each leaf. - Cells of the protective layer become coated and impregnated with suberin.
15 Abscission In early autumn, in response to the shortening days and declining intensity of sunlight, leaves begin the processes leading up to their fall. The veins that carry fluids into and out of the leaf gradually close off as a layer of cells forms at the base of each leaf. These clogged veins trap sugars in the leaf and promote production of anthocyanins. Once this separation layer is complete and the connecting tissues are sealed off, the leaf is ready to fall.
