The correct option is THE ELECTRON IN THE OUTERMOST ELECTRON SHELL.
Different levels of energy exist in the atom of an element and these levels are filled with electrons. The electrons in the innermost shell has the lowest energy level while the electrons in the outermost shell has the highest energy level. For an electron to increase its energy level, it has to move to an higher shell; and to decrease its energy level it has to move to a lower shell.
Answer:
the first question answer is C and for the second one is D
Answer:
Explanation:
Phloem cells are conducting vessels that are found in vascular plant. They are used in the transport of photosynthate produce during photosynthesis from the source of production to other parts of the body.
It consist of sieve elements, which are the conducting vessel that aids transport of sugar round the body. They are very active before maturity at mature they are no longer in use.
Companion cells are used in replacement of sieve element at maturity, they function in metabolism together with the sieve tube Translocation is the transport or movement of sugar round the body.
Girdlings is the removal of the bark of a plant this can inhibit active transport of food.
Non-reducing sugar are monosacharrides such as glucose that are produce and transported round the body of the plant.
P-protein are found in the plants sap usually in large amount in the sieve elements.
