The correct answer is: nitrogen, which is not present in glucose, but it is present in auxin.

Nitrogen is one of the essential elements of plant which is involved in plants’ metabolic processes. It is being absorbed from the soil in the form of nitrate ions. Since nitrogen is important and often a limiting factor for plants, it is present in different fertilizers.

One of the roles of nitrogen in plants is structural. It is component of amino acids and nucleic acids. Also, present in the chlorophyll.

Nitrogen enhance the rate of photosynthesis and improves growth and development of the plant..

Which descriptions apply to a chloroplast?
jenyasd209 [6]

Answer: (A) a membrane‑bound organelle with stacks of thylakoid discs called grana.

(E) the main site of photosynthesis in a plant cell.

Explanation:

The plant chloroplast is a large organelle, it is bounded by a double membrane like structure that is chloroplast envelop.

The chloroplast consists of chlorophyll pigment which traps the light energy from sun and converts it into chemical energy in the form of ATP. Thus the chloroplast is the main site for photosynthesis. Including the inner and outer membrane structure it also posses the third internal membrane structure which is called as the thylakoid membrane. The thylakoid membrane forms the network of flat discs which are called as thylakoids, the thylakoids are arranged in stacks which are called as grana.

The thylakoid membrane is the center point for the synthesis of ATP through a chemiosmotic process.

In what circumstances might it be important to use gel electrophoresis to separate and identify plasmids and short linear pieces
nadya68 [22]
I believe using gel electrophoresis to separate and identify plasmids and short linear pieces of DNA would be important if one is making a recombinant plasmid and has to verify that he/she has been successful. Gel electrophoresis is a technique that is used to separate mixtures of DNA, RNA, or proteins according to molecular size. The molecules being separated are pushed by an electrical field through a gel that contains small pores.
