Explanation:
Transportation in plants is an interesting process. It includes the transport of all the nutrients and water to all parts of the plant for its survival. In case of plants, the biggest concern is the transport of water and it terminates at the limiting factor depending on its growth. To overcome this problem, a tree uses several processes like Translocation, Storing, Absorption and Utilization of water
Definition of Transportation in plants
Transportation is the process of transporting water, minerals and food to all parts of the plant body.
Transport in plants occurs at three levels:
The uptake and release of water and solute by individual cells.
Short distance transport of substances from one cell to another.
Long distance transport of sap within xylem and phloem.Direction of transport is an important aspect in plants. In case of rooted plants, transport in xylem of both minerals and water is unidirectional from roots to stems. In this, mineral and organic nutrients undergo multidirectional transport. It includes the organic compounds that are formed during photosynthesis are exported to all parts of the plants along with storage organs. Plant growth regulators, hormones and chemical stimuli are also transported in unidirectional or polarized manner, in very small amounts, from where they are formed to other parts

How cells extract energy from glucose in the absence of oxygen. In yeast, anaerobic reactions produce alcohol, while in your muscles, they form lactic acid.
Both processes can happen thanks to alternative glucose degradation pathways that occur when normal cellular respiration that uses oxygen (aerobic) is not possible, that is, when there is no oxygen available that acts as an acceptor at the end of the transport chain of electrons. These fermentation pathways include glycolysis with a few extra reactions at the end. In yeast, the extra reactions produce alcohol; in the muscles, lactic acid.
Fermentation is a widespread route, but it is not the only way to obtain energy from fuels anaerobically (in the absence of oxygen). Some living systems use a different inorganic molecule instead of
