McMaster University. McMaster University (commonly referred to as McMaster or Mac) is a public research university located in Hamilton, Ontario, Canada. The main campus is located on 121 hectares (300 acres) of land near the residential neighbourhoods of Ainslie Wood and Westdale, adjacent to Hamilton's Royal Botanical Gardens.
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.
In supplying the plant with assimilates, the leaf, with the aid of other organs, supplies itself with water, mineral elements, and certain stimulating substances (such as kinins). Accordingly, the leaf has a number of features that are characteristically important for the performance of its functions.
