Answer:
It is true to say that by using cuttings, exact genetic characteristics can be maintained, because the cuttings retain the same genetic information about the plant from which they were extracted.
Explanation:
Cuttings are buds or branches extracted from a plant to obtain a plant of the same species, through a type of asexual reproduction.
Once separated from the "progenitor" plant, the cutting is provided with a suitable medium for growth, and will have the possibility of growing roots, developing and growing as an independent plant, with the same genetic characteristics of the original plant, as if it were a clone.
In this reproductive process, man intervenes.
Price of photosynthesis will increase as the quantity of collisions between enzymes and substrate will increase. this is the top-quality temperature. The enzymes begin to denature, so the fee of photosynthesis decreases.
Increase in enzyme attention will growth the charge of photosynthetic and respiratory reactions, furnished that there are substrates available to bind to. once all substrate is bound by enzymes, the reactions, the response will no longer increase, since there may be not anything for extra enzymes to bind to.
Enzymes are proteins that catalyze, or affect the fee, of chemical reactions without themselves being altered inside the process. precise enzymes catalyze every mobile reaction. the main position of enzymes at some point of the respiratory reaction is to help in transferring electrons from one molecule to some other.

Physical ......................................................
"chloroplast and animals" are not a match, since chloroplast only exists in plants and smalls cells for the purpose of utilizing photosynthesis. Animals do not require this process.
Transpiration is the rate of the water vapour exhalation by the plant cells through its opening pores. The correct blanks are guard cells and closing.
<h3>What is the structure of plant cells regulating transpiration?</h3>
Plant cells have certain specialized cell organelles that help in maintaining the rate of the carbon dioxide and the water content in their cells.
Stomata of the plant cells are specialized organelles that maintain the water and rate of transpiration by the plants. They have guard cells surrounding them that regulates their opening and closing.
The guard cells of the stomata form pores of the stomatal opening. The opening and the closing of the pores are regulated by the bulge and the carbon and the water intake and outtake of the cell is maintained.
Therefore, option A. <u>guard cells</u> and <u>closing </u>are the correct blanks.
