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.

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
What does c4 plants make when malate in the mesophyll cells that enters bundle sheath cells?
C4 plants make a 4 Carbon sugar in the mesophyll cells that enter the bundle sheath cells
What cell contains chlorophyll?
Guard cells and mesophyll thats all i remember
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.
CAM plants are similar to c3 plants because what?
photosynthesis occurs in chloroplasts of mesophyll cells
What cell contains chlorophyll?
Guard cells and mesophyll thats all i remember
Do tissues make sugar in plants?
Glucose and sucrose are produced through photosysnthesis in the chloroplasts in the mesophyll cells of the plants
Where is gluconse made in plants?
glucose is made in the "palisade mesophyll cells". glucose is made by photosynthesis which takes place in chloroplasts. chloroplasts are only found in palisade mesophyll cells. hope this helps
Does a leaf mesophyll have a nucleus?
i dont know! my biology teacher asked me the same thing
Where is palisade cell found?
Palisade cells are plant cells found within the mesophyll in leaves of many plants, right below the upper epidermis and cuticle. They are vertically elongated, a different shape from spongy mesophyll cells beneath them in the leaf.
In which type of tissue does photosynthesis take place in a leaf?
Photosynthesis takes place in the chloroplasts. Chloroplasts are organelles found in the cells of plants that conduct photosynthesis.
