Plant organs

Plant organs

Plant parts having rather distinct form, structure, and function. Organs, however, are interrelated through both evolution and development and are similar in many ways.

Roots, stems, and leaves are vegetative, or asexual, plant organs. They do not produce sex cells or play a direct role in sexual reproduction. In many species, nevertheless, these organs or parts of them (cuttings), may produce new plants asexually (vegetative reproduction). Sex organs are formed during the reproductive stage of plant development. In flowering plants, sex cells are produced in certain floral organs. The flower as a whole is sometimes called an organ, although it is more appropriate to consider it an assemblage of organs. See Flower, Fruit, Leaf, Reproduction (plant), Root (botany), Stem

Therefore, evaluations of chemical composition and accumulation of nutrients in the various plant organs provide important information for the understanding on the nutritional demands of the crops, since such information can be later used as a reference to calculate the dose of nutrients to be supplied to plants through fertilization (Laviola & Dias, 2008).
The new inks are based on biomimetic hydrogel composites containing cellulose fibrils that are derived from wood and similar to the microstructures in plant cell walls that enable plant organs, such as tendrils, leaves, and flowers, to exhibit dynamic morphologies that change in response to environmental variations (humidity and/or temperature).
B levels in leaves and roots in treatments where the micronutrient was omitted were the same for both banana genotypes; however, in the rhizome, although not differing between genotypes, B levels were lower when compared to other plant organs (Table 2).
