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 else can I help you with?
Where are the palisade mesophyll cells located?
Palisade mesophyll cells are located in the upper layer of the leaf tissue called the mesophyll. They are typically found just beneath the upper epidermis of the leaf in plants. Their role is in photosynthesis, where they absorb light energy and carry out the process of photosynthesis.
What does c4 plants make when malate in the mesophyll cells that enters bundle sheath cells?
When malate in the mesophyll cells enters bundle sheath cells in C4 plants, it undergoes decarboxylation to produce pyruvate and CO2. This CO2 is then used in the Calvin cycle within the bundle sheath cells to produce sugars, while the pyruvate is recycled back to the mesophyll cells to continue the C4 cycle.
In C4 and CAM plants carbon dioxide is fixed in the of mesophyll cells?
In C4 plants, carbon dioxide is initially fixed in the mesophyll cells by the enzyme PEP carboxylase, forming a 4-carbon compound before being transferred to bundle sheath cells. In CAM plants, carbon dioxide is fixed in the mesophyll cells at night and stored as organic acids until daylight when it is released and used in the Calvin cycle.
Where are most photosynthetic cells in plants found?
Most photosynthetic cells in plants are found in the mesophyll layer of the leaves. This layer contains the palisade and spongy mesophyll cells, which are responsible for carrying out photosynthesis. These cells contain chloroplasts that capture sunlight and convert it into energy for the plant.
What is defined as the functional tissue within a leaf that contains chlorophyll?
The functional tissue within a leaf that contains chlorophyll is called the mesophyll. Mesophyll cells are responsible for photosynthesis, the process by which plants convert light, carbon dioxide, and water into glucose and oxygen. The two types of mesophyll cells are palisade mesophyll and spongy mesophyll.
True or false spongy mesophyll are cells in a leaf?
True. Spongy mesophyll cells are found in the leaf tissue of plants and are involved in the exchange of gases necessary for photosynthesis.

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.
In C4 and CAM plants carbon dioxide is fixed in the of mesophyll cells?
In C4 plants, carbon dioxide is initially fixed in the mesophyll cells by the enzyme PEP carboxylase, forming a 4-carbon compound before being transferred to bundle sheath cells. In CAM plants, carbon dioxide is fixed in the mesophyll cells at night and stored as organic acids until daylight when it is released and used in the Calvin cycle.
What is mesophill cell?
Mesophyll cells are specialized plant cells found in the interior tissue of leaves. They are responsible for photosynthesis, as they contain chloroplasts where this process occurs. Mesophyll cells can be categorized into palisade mesophyll cells and spongy mesophyll cells, depending on their location and function within the leaf.
CAM plants are similar to c3 plants because what?
photosynthesis occurs in chloroplasts of mesophyll cells

Where tissue layer is responsible for most of the food production in plants?
The tissue layer responsible for most of the food production in plants is the mesophyll tissue, specifically the palisade mesophyll cells. These cells contain numerous chloroplasts where photosynthesis occurs, converting sunlight into energy for the plant.
Do tissues make sugar in plants?
Glucose and sucrose are produced through photosysnthesis in the chloroplasts in the mesophyll cells of the plants
