Leaves are colored by molecules called pigments. The pigment that causes leaves to be green is chlorophyll. Chlorophyll is important for plants to make food using sunlight. During spring and summer when there is plenty of sunlight, plants make a lot of chlorophyll.

Pasteurisation is one type of food preservation method. Pasteurisation is the process developed by Louis Pasteur, especially to store milk. In pasteurisation, milk is first heated to about 70 degrees Celsius for 15 to 30 seconds. Then it is suddenly chilled and stored. This prevents the growth of microbes. Pasteurisation deactivates the microbes and reduces the enzyme activity by reduction of temperature.

The pattern in arrangement of veins in the blade of a leaf is called as venation. Two types of venation are reticulate venation and parallel venation.
Reticulate venation involves net-like pattern of arrangement of veins. Most of the angiosperms with two cotyledons in the seed exhibit reticulate venation. e.g. Rose, Maple, Tulsi, Hibiscus, Red gram etc.
Parallel venation involves smaller veins running parallel to each other. Most of the monocot plants exhibit parallel venation in their leaves. e.g. Grains, banana, palm, onions, and grass etc.
Leaves in monocots show parallel venation whereas leaves in dicots show reticulated venation.

Sedimentation: Insoluble particles settle down at the bottom and the process is called sedimentation. For example; muddy water contains soil and sand in water. Soil and sand; being insoluble in water; settle down at bottom if water is allowed to stand for some time.
Decantation: This process is used after sedimentation. The upper layer; which contains water is slowly poured out from the container. It leaves the sediment behind.

- The main flat area is called the blade or lamina.
- Small processes located to either side of the base of the petiole are called the stipule.
- In some leaves there is no stipule for example. Nearly every leaf has a leaf stalk.
- The leaf stalk is called the petiole. The petiole attaches to the stem at a point called the leaf axil. Leaves can store food, water and minerals and these are transported through the veins and stem.
