Answer:
All the above
Explanation:
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports fluids between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue.
Stems have four main functions which are:[1]
Support for and the elevation of leaves, flowers and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits.
Transport of fluids between the roots and the shoots in the xylem and phloem(see below)
Storage of nutrients
Production of new living tissue. The normal lifespan of plant cells is one to three years. Stems have cells called meristems that annually generate new living tissue.
Global warming increases the amount of carbon in the atmosphere.
It is depicted as Complementary DNA of cDNA. It is frequently utilized as a part of quality cloning or as quality tests or in the production of a cDNA library. At the point when researchers exchange a quality from one cell into another cell with a specific end goal to express the new hereditary material as a protein in the beneficiary cell, the cDNA will be added to the beneficiary , on the grounds that the DNA for a whole quality may incorporate DNA that does not code for the protein or that intrudes on the coding arrangement of the protein.
