Why do C4 plants occur in deserts?
Why do C4 plants occur in deserts?
C4 plants occur more commonly in desert conditions because they do not have to keep their stomata open as long.
Why are C4 plants more suited to hot climates?
Why are C4 plants more suited to hot climates than C3 plants? They continue to fix carbon dioxide under low concentrations of gas. The use of non-C3 and non-CAM plants as crops may be limited in some regions because on hot, dry days, they close their stomata.
How is photosynthesis similar in C4 C 4 plants and CAM plants?
ATP and NADPH. How is photosynthesis similar in C4 plants and CAM plants? In both cases, rubisco is not used to fix carbon initially. ATP and NADPH are both products of the light reactions and are used to power the Calvin cycle.
What are some examples of C4 plants?
Examples of C4 plants include corn, sorghum, sugarcane, millet, and switchgrass. However, the C4 anatomical and biochemical adaptations require additional plant energy and resources than C3 photosynthesis, and so in cooler environments, C3 plants are typically more photosynthetically efficient and productive.
Which of the following do C4 plants and CAM plants have in common?
Which of the following do C4 plants and CAM plants have in common? Both fix CO2 into an initial 4-carbon compound. What is the driving force for the production of ATP in the light reactions?
Which character make C4 plants special?
C4 plants have the special type of leaf anatomy called Kranz anatomy. They can tolerate higher temperatures and show a response to high intensities of light. They have two types of cells i.e., mesophyll cells and bundle sheath cells, which are required for C4 pathway.
What is the significance of the C4 pathway?
1: The C4 Pathway The C4 pathway is designed to efficiently fix CO2 at low concentrations and plants that use this pathway are known as C4 plants. These plants fix CO2 into a four carbon compound (C4) called oxaloacetate. This occurs in cells called mesophyll cells.
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.
Which one of the following is an example of a Photoautotroph?
Green plants and photosynthetic bacteria are examples of photoautotrophs. They are not to be confused with photoheterotrophs, which also make energy from light but cannot use carbon dioxide as their sole source of carbon, and instead use organic materials.
What kind of habitat does a C4 pathway plant favor?
C4 plants are adapted to hot, dry environments, and include the important human food crops of maize, millet, sorghum, and sugar cane, as well as tropical savannah grasses and sedges.
What do you mean by C4 plants?
C4 plants are plants which cycle carbon dioxide to 4-carbon sugar compounds in order to enter the C3 or the Calvin cycle. The C4 plants are very productive in climatic conditions that are hot and dry and produce a lot of energy.
How is 30 ATP used in C4 cycle?
In the C4 cycle of photosynthesis, a total of 30 ATPs are required for fixing 6CO2 molecules.
Where does primary carboxylation occurs in C4 plants?
mesophyll cells
