Leaf and fruit are easy, yes - but there are many more parts of plants that are used for human nutrition and supplementation. We have compiled a small overview for you - and no, it is not a complete list:
Leaves
Along with the shoot axis and root, the leaves are one of the basic organs of higher plants. Their functions are photosynthesis and the evaporation of water.
Many of the plant extracts for dietary supplementation are made from the leaves.
Flower, petals
Flowers are used for reproduction, because after pollination the fruit with seeds is formed from you.
Fruit
A fruit is a seed-ripe flower. Fruits are only found in angiosperms, i.e. angiosperms that develop from one or more carpels. Often, the skin of a fruit is also processed.
Tubers
A tuber is a thickened part of a plant that serves as a storage organ and, in many cases, for vegetative propagation. There are shoot tubers, root tubers and hypocotyl tubers. In the latter, the lower part of the shoot axis, i.e. the hypocotyl, is thickened.
Bark
Rhizome
A rhizome is a shoot axis system that usually grows underground. It is not a root, but a horizontally growing shoot axis with thickened internodes, leaf naevi, and a vascular bundle arrangement. Scaly stipules may serve as storage organs.
Beet
Beets are thickened storage organs of a plant. It arises i.a. from the thickening of the main root including the lowest shoot section. The beet is either underground, protruding from the soil or located above it.
Seeds
Seeds are used by seed plants for propagation and consist of seedling, nutritive tissue and seed coat.
Shoot axis - step, stem, shaft, stalk
The shoot axis connects the roots and leaves. It carries the foliage and directed it to photosynthesis. Functions are stabilization, storage and especially transport of water, nutrients and photosynthesis products.
Roots
Roots generally grow underground and secure the plant in the soil. They serve to absorb water and nutrients and as a storage organ for the plant.
