Answer:
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings.
Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consistency throughout their crops.

Prokaryotic organisms are separated into two domains or groups: Bacteria and Archaea.
<h3>What are prokaryotic organisms?</h3>
Prokaryotic organisms are those whose cells do not have a membrane that delimits the cell nucleus and, instead, present their genetic material dispersed in an area called the nucleoid.
<h3>Characteristics of p
rokaryotic organisms</h3>
- Prokaryotic cells form unicellular living organisms, belonging to the Archaea and Bacteria domains, depending on the preferred biological classification.
- The Bacteria domain groups the most primitive prokaryotic organisms of all, they are dedicated to various types of metabolic activity: photosynthesis, such as cyanobacteria (blue-green algae), the decomposition of organic matter, etc.
- The Archaea domain groups the archaebacteria or archaea, prokaryotic organisms that exhibit certain similarities with eukaryotic life, exist in very specific and generally hostile habitats (leading an extremophile life).
Therefore, we can conclude that the two domains, bacteria and archaea, encompass the world of prokaryotic organisms, that is, those that lack a cell nucleus.

1. Diffusion: Diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room
2.Osmosis: a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
3. Facilitated diffusion: Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins.
4. Protein pumps: a kind of protein that is capable of pumping out compounds that could pose a threat to the cell. An example is AcrB, a bacterial protein complex that repels a wide range of antibiotics through its ability to capture and pump out a spectrum of structurally diverse compounds
5.exocytosis: a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.
6.endocytosis: Endocytosis definition and purposes. Endocytosis is the process by which cells take in substances from outside of the cell by engulfing them in a vesicle. These can include things like nutrients to support the cell or pathogens that immune cells engulf and destroy.
