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.

∙ 14y agoThe C4 plants have thicker bundle sheath cell layers in comparison to C3 plants. Additionally, in the C4 plants, chloroplasts is presence in both bundle sheath cells and mesophyll cells, where in C3 plants it only presence in the mesophyll cells.

∙ 9y agoC4 plants have bundle-sheath and mesophyll cells that are concentrically arranged into tightly packed sheaths around the veins of the leaf known as Kranz anatomy. However in C3 plant, these distinct vein anatomy arrangement is absent. Mesophyll cells between the veins are usually 4 or more which isn't the case in C4 with an approximately 1:1 ratio of bundle sheath and mesophyll cells making an efficient CO2 transport and carbon fixation.

∙ 9y agoC3 plants fix carbon dioxide into glyceraldehyde-3-phosphate. C4 plants fix carbon dioxide into oxaloacetate. C4 plants also live in the desert.

∙ 10y agoThe C3 plants are the regular everyday plants. The C4 plants have two separate cells the mesophyll cells and the bundle sheath cells.

What do c3 and c4 plants have in common?
C3 and C4 plants are named after the number of carbon molecules in the first products of their carbon fixation cycles. C3 plants produce 3-phosphoglycerate and C4 plants produce Oxaloacetate.
How do C4 and C3 plants differ?
c4 plants have first product of calvin cycle is oxaloacetic acid but in c3 plants is phospfoglyceric acid
Are C3 or C4 plants aquatic?
The plants which live in water are aquatic plants.
In what climates do C4 and C3 fixation happen more efficiently?
In hot, arid conditions, C3 and C4 plants have to partially close their stomata to reduce water loss. However, this inhibits photosynthesis. Therefore, C3 and C4 plants are photosynthetically more efficient in more temperate environments.
In C3 plants the conservation of water promotes?
Cam stands for Crassulacean acid metabolism. C3 and C4 conserve less water than Cam plants. Actually, C4 plant capture more carbon than C3 plant. In the struggle to reduce carbon dioxide concentration in the atmosphere, genetic scientists have modified some large scale crops into C4 bases. Cam plant is wholly different from C3 and C4 and examples of are the cactus and other succulent plants in order to survive in dry dusty regions. In Cam plants, [http://en.wikipedia.org/wiki/Carbon_fixation carbon fixation] occurs at night while C3 and C4 plants carry out photosynthesis during daylights.
Are tomatoes C3 or C4 plants?
C3
Are C4 plants larger than C3 plants?
c3
What do c3 and c4 plants have in common?
C3 and C4 plants are named after the number of carbon molecules in the first products of their carbon fixation cycles. C3 plants produce 3-phosphoglycerate and C4 plants produce Oxaloacetate.
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.
How do C4 and C3 plants differ?
c4 plants have first product of calvin cycle is oxaloacetic acid but in c3 plants is phospfoglyceric acid
What would be the expected effect on plants if the atmospheric co2 concentration was doubled?
Since C4 plants need for CO2 is more than C3 plants, doubling the concentration of CO2 will have more positive effect on C4 plants. If CO2 is a limiting factor for photosynthesis, both C3 & C4 plants will have positive effect.
Are C3 or C4 plants aquatic?
The plants which live in water are aquatic plants.
Are zonal geraniums C3 plants?
yes more like c4 plants
In what climates do C4 and C3 fixation happen more efficiently?
In hot, arid conditions, C3 and C4 plants have to partially close their stomata to reduce water loss. However, this inhibits photosynthesis. Therefore, C3 and C4 plants are photosynthetically more efficient in more temperate environments.
Is sunflower c3 or c4 plant?
c4
Why C4 plants efficient in law water than C3 plants?
the question doesn't make sense
C3 and c4 plants in terms of the number of?
They are named after the number of carbons of the first product of their carbon fixation cycle (the cycle used to make plant sugars). C4 plants have a more elaborate carbon fixation cycle of C3 and reduces photorespiration. They are thought to have evolved more recently than C3 plants.
