The diference between C3 and C4 plants?

plant A is begonia which is a C3, plant b is a pineapple which is a C4, and plant C is a





cactus which is a CAM in a few weeks only plant alive is cactus. Careful records indicate





that the begonia died first


then pineapple


based on this info...explain wat happened


How was the cactus able to "kill" the other two, and why did thebegonia die first

The diference between C3 and C4 plants?
I won't do your homework for you, but I will give you a few hints.





The first hint is that ddnight is talkin' smack. This has nothing to do with atmosoheric composition.





The second hint is that you should be looking very varefully at the relative effect of C4 and CAM utilisation on water LOSS. Underline the word 'loss".

Generally yes. But the question is why the plants died in that order. Begonia are tropical plants, so a temperature would not have killed it, and the pineapple is both tropical nad C4, sdo temperature effects can't be at play directly.





Only one plausible explanation remains.
Reply:C3 species continue to increase photosynthesis with rising CO2 , while C4 species do not. So, C3 plants that can respond readily to higher CO2 levels, and C4 plants can make only limited responses.





Thus increased CO2 likely will mean that some plant species will be stronger, more prolific, and may overwhelm those less able to benefit.
Reply:I don't know what your teacher's looking for on this but I would be looking at temperature differences as well. CAM plants and C4's do better in higher temps than C3's.
