Stems

D
Leaves
Explanation: 

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: -As well as these characteristics, the margins (edges) of the leaf are also used to identify plants – for example, whether the margin is smooth, toothed or serrated. Some leaves such as kōwhai and Pseudopanax spp. have compound leaves and are composed of several leaflets.

Detailed explanation-3: -Plant ID Tips Take a look at the shape of the leaf when identifying flowers by their leaves. The leaf shape can be round, oval or oblong, lance shaped, or elliptic. The pattern of veins in the leaf can also help you figure out the type of plant you are dealing with. Are the veins parallel?

Detailed explanation-4: -In biology, an identification key, taxonomic key, or biological key is a printed or computer-aided device that aids the identification of biological entities, such as plants, animals, fossils, microorganisms, and pollen grains.
