In this way, the distinction between a definition of morality and a moral theory parallels the distinction John Rawls (1971: 9) drew between the general concept of justice and various detailed conceptions of it.
Leaves are the site of the food making process called photosynthesis. In this process, carbon dioxide and water in the presence of chlorophyll (the green pigment) and light energy are changed into glucose (a sugar). This energy rich sugar is the source of food used by most plants.
Plants are capable of manufacturing food through a process known as photosynthesis. The process involves taking one form of energy -- sunlight -- and changing it to another form of energy -- sugar -- that the plant can use more readily.lants are capable of manufacturing food through a process known as photosynthesis.
