Sun leaves become thicker than shade leaves because they develop longer palisade cells or an additional layer of palisade cells.
On a weight basis, shade leaves generally have more chlorophyll. This is because the chloroplasts have more grana - you can look this up in a more advanced text book if you would like to know the details of chloroplast structure. In shade leaves, the chloroplasts move within the cells to take up a position where they will absorb the maximum light without shading other chloroplasts below them. This is hard to determine but these conditions can exist under or near trees that have less than 50 percent canopy.
It can also be found in the reflections of light off of buildings. Another way to look at partial shade would be more cooler morning sun and little or no hot afternoon sun.
Full shade is the third type of shade. These areas take in less than an hour of direct sunlight each day. It could also be dappled light through a tree canopy for most of the day. Full shade is not just a result of trees but also buildings, fences and other structures that cast shadows or block the sun rays.
When planting in full shade soil moisture can be an issue. Dry shade presents additional challenges for plant selections as the competition with tree roots can be high. Plants in this area should not only be shade tolerant but also drought tolerant unless supplemental water will be applied. Dense shade is the last in this category. It which means no direct sunlight and little indirect light seldom reaches the ground.
This would be the light under evergreen trees or overhangs of buildings. It can be found under shrubs, decks and dark corners and passages between houses. The ground is usually dry and dark from lack of light. Dense shade is the most difficult and limiting growing condition. Plant selections are few due to the combination of shade, root competition, and dry soil conditions. Decorative mulches or ground covers are good alternatives for areas with dense shade.
What does the plant need? Read the tag. Understanding the sun and shade patterns of the garden is only part of the equation. The second part is understanding the plant needs. Here again this can be confusing as plants can adapt to several light levels. The adaptation is related in many ways to the intensity of the sunlight. Remember morning sun is cooler and less intense. It does not lead to leaf scorch and stress.
Some plants can tolerate a lot more sun if it was morning sun as opposed to the hot, scorching afternoon sun. Plant growers try to help us figure out the needs.
