Artificial selection or selective breeding is a process of selecting the “advantageous” characteristics from the plants or animals by humans and using them for breeding. There are many advantages of artificial selection:
• More agricultural products, gaining higher profit (for example more milk from cow, or more fruit)
• Elimination of diseases by identifying the plants/animals with disease
• Production of superior breed.
On the other hand, negative effects might also occur, so the disadvantages of artificial selection are:
• Genetic mutations
• Loss of genes
• Diseases
All of these negative impacts are connected and often arise from the breeding of desirable organisms.

The high turgor pressure drives movement of phloem sap by “bulk flow” from source to sink, where the sugars are rapidly removed from the phloem at the sink. Removal of the sugar increases the Ψs, which causes water to leave the phloem and return to the xylem, decreasing up
