Leaves are the powerhouse of plants. In most plants, leaves are the major site of food production for the plant. Structures within a leaf convert the energy in sunlight into chemical energy that the plant can use as food. Chlorophyll is the molecule in leaves that uses the energy in sunlight to turn water (H2O) and carbon dioxide gas (CO2) into sugar and oxygen gas (O2). This process is called photosynthesis.
I am about to go out to my fave grassland, but rainshower suddenly came and forced me to back out. What I got here is the leaves of the chestnut tree. I just use my zoom lens for this shots.
