Ever wondered how an entire plant is produced under laboratory conditions in a test tube from any of its parts ? Don't think too much . Here is the answer. Because each and every cell in plant are totipotent. That means any single cell is capable of giving rise to any cell type. More precisely totipotency is the ability of a plant to grow an entire plant from an individual cell. It makes the plants different from animals. This is the main principle behind tissue culture.

All the plants can undergo cellular differentiation if we provide appropriate conditions for them in a laboratory. In animals zygote is the only cell that can undergo differentiation and capable of developing into all the specialized cells that make up the adult animal.

Upon illumination, enzymes are formed inside the proplastid or imported from the cytosol; light-absorbing pigments are produced; and membranes proliferate rapidly, giving rise to stroma lamellae and grana stacks (Figure 1.23B). (...) If, instead, germinated seedlings are kept in the dark, the proplastids differentiate into etioplasts, which contain semicrystalline tubular arrays of membrane known as prolamellar bodies (Figure 1.23C).

Schon im März 2022 hat die Band Meristem aus Ungarn ihre erste EP namens “Necrosis” veröffentlicht. Das “erste” bezieht sich hier auf: zum ersten Mal mit Vocals.
