The leaf is a green flattened structure that arises from the node of a stem or a branch. It has three main parts - leaf base, stalk or petiole, and leaf blade or lamina. Its main function is to carry out photosynthesis.

A flower is the reproductive part of a plant body. It develops into a fruit that bears seeds. It is the most important part meant for the multiplication of the species. A flower is made up of different parts- sepals, petals, stamens, and pistil.

The veins present on a leaf are responsible for the transfer of water and minerals in the leaves. The leaf venation refers to the pattern or arrangement of veins on a leaf. Reticulate and parallel venation are the two types of venation.

The plants with weak stems need support for climbing the surrounding structures like walls, trees, etc. These plants are called climbers. Example: pea, money plant, etc.
