Which of the following statements about c3 carbon fixation is true?

a. c3 carbon fixation is an adaptations for plants exposed to high light intensity.
b. c3 carbon fixation occurs in more plants and then c4 carbon fixation.
c. c3 carbon fixation is more common in the areas of high temperature is then c4 carbon fixation.
d. c3 carbon fixation occurs in the inner cells of a leaf rather than the entire leaf.

C3 fixation is one of the three processes that plants use to fix carbon during the process of photosynthesis. The otehr two are C4 and CAM fixation. The following statement about C3 carbon fixation is true: C3 carbon fixation occurs in more plants than C4 carbon fixation. Correct B

During the C3 fixation the enzyme RuBisCO (ribulose bisphosphate carboxylase/oxygenase) causes an oxidation reaction in which some of the energy used in photosynthesis is lost in a process known as photorespiration.

the correct option is option d

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
