Plants make food in their leaves. The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.
Leaves [edit]. It is through its leaves that a plant will absorb light from the sun, and utilize it in the photosynthesis process, similar to a solar panel. In general terms leaves could be regarded as sensory organs, lungs and a secondary mouth.A plant's leaves are usually the first to show signs that something is wrong with it.ellowing of the Leaves (from the bottom of the plant upward) [edit]. This can be a sign of nitrogen deficiency or of over fertilization. If accompanied early by browning and necrosis of the leaf tips then you may be over fertilizing.
