DENDROLOGY

Detailed explanation-1: -Leaves are often the basis for identifying plants since they are so easily observed. They usually consist of two parts, the blade, the wide or more obvious part of a leaf, and the “stalk” or petiole by which the blade is attached to the stem.

Detailed explanation-2: -The most common leaves are the kind you find on angiosperms, or flowering plants. That includes most shrubs and deciduous trees. This is the classic leaf, a skeleton of veins with a membrane between them. These leaves are delicate, but very efficient.

Detailed explanation-3: -Plants take in carbon dioxide, water, and sunlight and make glucose (sugar) and oxygen. Plant leaves contain chlorophyll pigment which is responsible for capturing the sun’s energy to carry out photosynthesis. Pigments are chemicals that absorb visible light.
