What is the main advantage of the C4 and CAM photosynthesis strategies?
What is the main advantage of the C4 and CAM photosynthesis strategies?
What is the main adaptive advantage of the C4 and CAM photosynthesis strategy over the C3 strategy? They help the plant conserve water and synthesize glucose efficiently under hot, dry conditions.
What is an advantage of the C4 photosynthetic strategy?
Plants that perform C4 photosynthesis can keep their stomata closed more than their C3 equivalents because they are more efficient in incorporation CO2. This minimizes their water loss.
What advantage do C4 and CAM plants have over C3 plants Why is this important?
C3 plants do not have special features to combat photorespiration, while C4 plants minimize photorespiration by performing carbon dioxide fixation and Calvin cycle in separate cells. CAM plants, on the other hand, minimize photorespiration by performing carbon dioxide fixation and Calvin cycle at separate times.
Why do C4 and CAM plants have an advantage when temperatures are higher?
The PEP also functions better at temperatures above 1⁵⁰ C. Both of these factors give C4 plants an advantage in hot, dry conditions. CAM, Crassulacean acid metabolism, photosynthesis produces 4 carbon atom sugars as in the C4 pathway but the CO2 is able to be fixed and stored at night.
What advantages do the two strategies adapted by CAM plants have?
1 Answer. Paul G. Crassulacean Acid Metabolism (CAM) has the advantage of essentially eliminating evapotranspiration through a plants stomata (water loss through gas exchange) during the day, allowing CAM plants to survive in inhospitable climates where water loss is a major limiting factor to plant growth.
Which plant is advanced among C3 C4 and CAM?
Difference Between C3, C4 and CAM pathway
| C3 | C4 | CAM |
|---|---|---|
| Beans, Spinach, Sunflower, Rice, Cotton | Maize, Sorghum, Sugarcane | Orchids, Cacti, euphorbias |
| Carboxylating enzyme | ||
| In C3, RuBP carboxylase | PEP carboxylase – mesophyll RuBP carboxylase – bundle sheath | RuBP carboxylase – day time PEP carboxylase – night time |
| Ratio – Co2:ATP: NADPH2 |
How is CAM photosynthesis advantageous in desert climates?
The process of photosynthesis in desert plants has evolved mechanisms to conserve water. Plants that use crassulacean acid metabolism (CAM) photosynthesis fix CO2 at night, when their stomata are open.
In what respect are the photosynthetic adaptations of C4 plants and CAM plants similar?
In both cases, only photosystem I is used. Both types of plants make sugar without the Calvin cycle. In both cases, rubisco is not used to fix carbon initially.
What makes C4 photosynthesis more efficient than C3 photosynthesis in tropical climates?
C4 plants are more efficient than C3 due to their high rate of photosynthesis and reduced rate of photorespiration. The main enzyme of carbon fixation (Calvin cycle) is RuBisCO, i.e. ribulose bisphosphate carboxylase oxygenase. It has an affinity for both CO2 and O2.
What advantage do C4 and CAM plants have in arid environments?
C4 and CAM plants are no like most plants, which are categorized as C3 plants, because they are more adapted to live in hotter environments where water is not readily available. The main difference between C4 and CAM plants is the way they minimize water loss.
What adaptations do CAM plants have?
Crassulacean acid metabolism (CAM) is a photosynthetic adaptation to periodic water supply, occurring in plants in arid regions (e.g., cacti) or in tropical epiphytes (e.g., orchids and bromeliads). CAM plants close their stomata during the day and take up CO2 at night, when the air temperature is lower.
What are CAM plants and what is their advantage?
Crassulacean acid metabolism (CAM) plants minimize photorespiration and save water by separating these steps in time, between night and day.
