Can you please help me with a simple and short answers please. Also no meed for explanation i just need answers.Thank you 6.3 Carbon Dioxide Uptake During the Calvin cycle reactions of photosynthesis, the plant takes up carbon dioxide (CO,) and reduces a carbohydrate, such as glucose (C.HO. Therefore, the carbon dioxide in the solution surrounding should disappear as photosynthesis takes place. it to Elodea Experimental Procedure: Carbon Dioxide Uptake 1. Temporarily remove the Elodea from the test tube. Empty the sodium Phenol red Avoid ingestion, inhalation, and bicarbonate (NaHCO) solution from the test tube, rinse the test tube thoroughly, and fill with a phenol red solution diluted to a faint pink. (Add more water if the solution is too dark.) Phenol red is a phH indicator that turns contact with skin, eyes, and mucous membranes. Follow ions tor your instructor's directions disposal of this chemicel. Use yellow in an acid and red in a base. Blow lightly on the surface of the solution. Stop blowing as soon as the surface color changes to yellow. Then shake the test tube until the rest of the solution turns yellow Blowing onto the solution adds what gas to the test tube? water, it forms carbonic acid; therefore, the solution appears yellow. protective eyewear when performing this experiment When carbon dioxide combines with 3. Thoroughly rinse the Elodea with distilled water, return it to the test tube which now contains a yellow 4. The water in the beaker used to absorb heat should be clear. 5. Turn on the lamp, and wait until the edge of the solution just begins to move upward. Note the time. 6, why did the solution eventually turn red? 7. The carbon cycle includes all the many ways solution, and assemble your volumeter as before. Observe until you note a change in color. How long did the color change take? that organisms exchange carbon dioxide with the atmosphere. Figure 6.6 notes the relationship between cellular respiration and photosynthesis. Animals produce carbon dioxide used by plants to carry out photosynthesis. Plants produce the food (and oxygen) that they and animals require to carry out cellular respiration. Therefore, the same carbon atoms pass between animals and plants and between plants and animals (Fig. 6.6). Solar energy Autotroph co Ho Glucose 0 Figure 6.6 Photosynthesis and cellular respiration. Animals are dependent on plants for a supply of axygen, and plants are dependent on animals for a supply of carbon dioxide. Cellular respiration Heterotroph 72 Laboratory 6 Photosynthesis 6-8
Explanation / Answer
2) Blowing onto the solution add up CO2 to the solution.
5) If concentration of carbon dioxide is more than 0.04%, the starting red color converts into yellow as the pH becomes more acidic. When the concentration carbon dioxide is less than 0.04%, it alters from red to magenta and, in comparatively very low carbon dioxide contents, to purple.
6) Carbon dioxide concentrations found in exhaled air, will solvate in the indicator to produce carbonic acid( weak acid), that will decreases the pH and show the characteristic colour change.
