Water potential is the measure of water to move from one area to another. Pure water has a water potential of 0. Water potential can never be positive, so a negative water potential has solutes in it. The more negative it is the more solutes present.
Answer:
C3 plants would have faster growth rates; C4 plants would be minimally affected.
Explanation:
C3 and C4 pathways are the variations of dark reactions of photosynthesis present in green plants. The photosynthetic efficiency of C3 plants is reduced due to the affinity of RuBisCo enzyme for oxygen which in turn leads to the futile pathway of photorespiration. RuBisCo enzyme catalyzes the rate-limiting reaction of the C3 pathway. On the other hand, the C4 plants concentrate CO2 around RuBisCo in their bundle sheath cells of leaves to minimize photorespiration and exhibit higher rates of photosynthesis.
Increased levels of atmospheric CO2 would reduce the photorespiration in C3 plants and would allow them to fix CO2 efficiently due to the increased concentration of CO2 around the enzyme RuBisCo. The increased photosynthetic efficiency would help these plants to exhibit faster growth rates.
However, the photosynthetic rate of C4 plants is not limited by CO2 concentration as they themselves reduce photorespiration by spatial separation of primary carboxylation in mesophyll cell and CO2 fixation in bundle sheath cells. Hence, increased CO2 levels in the atmosphere would not have any impact on their photosynthetic rate and growth.
Answer:Cellular respiration is the process of transforming chemical energy into forms usable by the cell or organism. Organisms ingest organic molecules like the carbohydrate glucose to obtain the energy needed for cellular functions. The energy in glucose can be extracted in a series of chemical reactions known as cellular respiration. Most energy is produced during cellular respiration in the mitochondria, a process that involves breakdown of simple sugars to produce energy in the form of ATP, which is the usable form by the cell.

Answer:
Saturated fats have no double bonds in their chemical structure. They are “saturated” with hydrogen atoms. Because of their chemical structure, they have a solid consistency at room temperature. Unsaturated fats are typically liquid at room temperature. They differ from saturated fats in that their chemical structure contains one or more double bonds. They can be further categorized as: 3
Monounsaturated fats: This type of unsaturated fat contains only one double bond in its structure. Monounsaturated fats are typically liquid at room temperature and include canola oil and olive oil.
Polyunsaturated fats: This type of unsaturated fat contains two or more double bonds in their structure. They are liquid at room temperature. Polyunsaturated fats include safflower oil, sunflower oil, and corn oil.
