Antibiotic used include kenamycin, ampicillin and tetracycline. This is useful to determine if and which bacteria took up the plasmid as they were supposed to during the process of recombination. Host bacteria are normally killed by these antibiotics. If the recombinant plasmids were taken up by the bacteria, plasmid may have contained a DNA gene for resisting the effects of one or more antibiotics. Host bacteria are placed in a growth medium containing an antibiotic to which they have a resistant gene in their recombinant plasmid DNA survivor. If they havent taken the plasmid they die.

Answer:
Guard cells
Explanation:
Guard cells are the cells that are found around the openings of the stomata, their functions is that they regulate the opening and closing of the stomata. These cells are always fill with latex which is of high percentage of water, therefore when the intake of water is low, the functionality of the cells will be affected.
And it must be noted that, the stomata is very important in the exchange of gases, that is a process where oxygen is released and carbon dioxide is absorbed. Therefore when the cells are affected, the gas exchange will also be effected.
