A dozen different species of plants growing in the shade

Shade is the blocking of sunlight (in particular direct sunshine) by any object, and also the shadow created by that object. Sunlight, in the broad sense is the total spectrum of the Electromagnetic radiation given off by the Sun. A shadow is an area where direct light from a light source cannot reach due to obstruction by an object It may refer to blocking of sunlight by a roof, a tree, an umbrella, a window shade or blind, curtains, or other objects. A tree is a perennial Woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or "Parasol" redirects here For other uses see Umbrella (disambiguation, Umbrella (song or Parasol (disambiguation For other uses see Blinds (disambiguation For the desktop theming software see WindowBlinds.

Shade is an important issue in temperate and tropical zones for providing cooling and shelter from the sun. The Tropics are centered on the Equator and limited in Latitude by the Tropic of Cancer in the northern hemisphere at approximately 23°26' (23 The Sun (Sol is the Star at the center of the Solar System. Providing certain configurations of shading is an important passive solar technique. For the application of passive solar technologies in buildings see Passive solar building design. This may be done with overhangs, with shade trees, or with vines. A shade tree is any Tree grown specifically for its shade This term usually applies to large trees with spreading canopies. A vine is any plant of Genus Vitis (the Grape plants or by extension any similar climbing or trailing plant Vines particularly suited for this purpose include Boston ivy, Virginia creeper, and morning glory.

Morning glory is a common name for over 1000 Species of Flowering plants in the family Convolvulaceae, belonging to the following genera

Shading using non-living materials blocks the sun, but also results in sunlight being absorbed and re-radiated as heat, or in sunlight being reflected as glare. Light pollution, also known as photopollution or luminous pollution, is excess or obtrusive Light created mainly by Humans Among other effects Green plants, on the other hand, not only absorb a significant portion of the sunlight to invest as energy in photosynthesis to produce sugar, but also actively transpire, producing an additional cooling effect. Photosynthesis is a Metabolic pathway that converts Light Energy into Chemical energy. Carbohydrates (from ' Hydrates of Carbon ' or saccharides ( Greek σάκχαρον meaning " Sugar " are the most

In gardening terms, there are various types of shade:

• Full sun - more than five hours of direct sun per day.
• Part shade - two to five hours of direct sun, or all-day dappled sun (sunlight shining through open trees).
• Full shade - less than two hours of direct sun per day.
