What specialized structure is found in C4 plants?
C4 plants have concentric rings of mesophyll cells around vascular bundle sheath in the leaves.
How do C4 and C3 plants differ?
C4 plants have an extra step in their photosynthetic pathway to minimize photorespiration, allowing them to be more efficient in hot and dry conditions compared to C3 plants. C4 plants, like corn and sugarcane, have specialized leaf anatomy with separate cells for carbon fixation, while C3 plants, like wheat and rice, lack this specialization.
C4 plants conserve water by?
C4 plants conserve water by reducing photorespiration, which leads to reduced water loss through transpiration. This is achieved through spatial separation of carbon fixation and the Calvin cycle in different cells within the leaf. This allows C4 plants to better handle dry and hot conditions compared to C3 plants.
What do c3 and c4 plants have in common?
C3 and C4 plants are both categories of plants based on the type of photosynthetic pathway they use. Both types of plants undergo the Calvin cycle to fix carbon dioxide and produce sugar during photosynthesis. However, C4 plants have an additional carbon-concentrating mechanism that allows for more efficient photosynthesis in hot and dry conditions compared to C3 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.

Is wheat a C4 plant?
Technically, the answer is no because it does not have the anatomical structure of C4 plants. However, it has adaptation similar to C4 plants with regard to carbon dioxide use efficiency. (Ref. Mineral nutrition of higher plants : 2nd edt : pg 140)

What is the value of Carbon dioxide compensation point in C3 and C4 plants respectively?
Around 50ppm for C3 plants and around 5ppm for C4 plants.

Are tomatoes C3 or C4 plants?
C3
Is crabgrass a c4 plant?
Yes, crabgrass is a C4 plant. C4 plants have a specialized mechanism for carbon fixation that allows them to adapt to hot and dry conditions, making them well-suited for growth in environments where C3 plants may struggle.
Is pine a C4 plant?
No, pine trees are not C4 plants. They are considered C3 plants, which means they use the C3 photosynthetic pathway to fix carbon dioxide. C4 plants have a different mechanism to concentrate carbon dioxide during photosynthesis.
What structure is dorsal to the thyroid?
C4 or C5 vertebra.
Is sunflower c3 or c4 plant?
Sunflowers are C3 plants. They use the C3 carbon fixation pathway during photosynthesis, which is less efficient in hot and dry conditions compared to C4 plants.
