Where are the palisade mesophyll cells located?
The palisade mesophyll organ belongs to the leaf organ.
In C4 and CAM plants carbon dioxide is fixed in the of mesophyll cells?
Cytoplasm of the mesophyll cells
Are the light reactions necessary in the mesophyll cells of C4 plants?
Yes, the light reactions are necessary in the Mesophyll cells of C4 plants. The reason light reactions should be done in the Mesophyll cells because it is essential in the making of CO2 for the Calvin Cycle in the bundle sheath cells. The Mesophyll cells do not contain Rubisco. Instead they fix carbon dioxide by combining it with a 3-carbon acid. Unlike Rubisco, the enzyme that catalyzes this reaction distinguishes well between carbon dioxide and oxygen. The resulting 4-carbon acid is rearranged and sends to the bundle sheath cells, as shown in Figure 4.22. There, carbon dioxide is released from the 4-carbon acid is rearranged and then transported to the bundle sheath cells, as shown in figure 4.22. There, carbon dioxide is released from the 4-carbon acid and fixed again by Rubisco, forming PGA by way of Calvin cycle.
What is the purpose of the hatch-slack pathway?
C4 fixation is an elaboration of the more common C3 carbon fixation and is believed to have evolved more recently. and CAM overcome the tendency of the enzyme RuBisCoto wastefully fix oxygen rather than carbon dioxide in what is called photorespiration. This is achieved by using a more efficient enzyme to fix in mesophyll cells and shuttling this fixed carbon via malate or asparate to bundle-sheath cells. In these bundle-sheath cells, RuBisCO is isolated from atmospheric oxygen and saturated with the released by decarboxilation of the malate or oxaloacetate. These additional steps, however, require more energy in the form of ATP. Because of this extra energy requirement, plants are able to more efficiently fix carbon in only certain conditions, with the more common pathway being more efficient in other conditions.
What is the importance of mesophyll tissue?
Mesophyll tissue is made up of parenchyma cells that lie between the upper and lower epidermis layers of a leaf. The parenchyma cells that make up this tissue are essential for photosynthesis in plants.
Similarities between c3 and c4 plants?
By looking at their anatomy, in C3 plants, bundle sheath cells do not contain chloroplasts; carbon fixation and Calvin Cycle reactions occur in mesophyll cells (and in the presence of oxygen). In C4 plants, the bundle sheath cells contain chloroplasts; carbon is fixed in mesophyll cells, then transported to bundle sheath cells where Calvin Cycle reactions occur in the absence of oxygen. In both, photosynthesized sugars then enter the plant's vascular system. C4 have a concentric arrangement of the bundle sheath and mesophyll layer, the bundle sheath is also thicker. Another difference is their intervenial distances, from one bundle sheath to another you have in C4 only around 4 mesophyll cells but on 3 they are separated by 12. Overall, C4 plants are more adapted to environments with more oxygen, and C3 plants are more adapted to environments with more carbon dioxide.
What specialized structure is found in C4 plants?
C4 plants have concentric rings of mesophyll cells around vascular bundle sheath in the leaves.
Where is mesophyll located?
Mesophyll is located within the leaves of most plants.
Where are chloroplasts located in green plants?
Chloroplasts are concentrated in the cell of the mesophyll. So mesophyll is your answer.
Where are the palisade mesophyll cells located?
The palisade mesophyll organ belongs to the leaf organ.

What is the kranz anatomy?
Kranz means wreath in German. Kranz anatomy refers to an arrangement of bundle sheath cells surrounded by mesophyll cells in C4 plants. This arrangement ensures that mesophyll cells are no more than 2-4 cell layers away from the bundle sheath cells. Hence, the transport of C4 cycle metabolites is facilitated via plasmodesmata through these two cell types. Note that Kranz anatomy is not mandatory for C4 cycle.

Glucose and sucrose are produced through photosysnthesis in the chloroplasts in the mesophyll cells of the plants
