does caffeine exist in most plants? I know that caffeine is found in tea and coffee, how about other herbs or flowers that are used in the same way.

Genius Cook replied: "No."

soupkitty replied: "Besides tea and coffee, caffeine also occurs in cacao pods and hence in cocoa and chocolate products; in kola nuts, used in the preparation of cola drinks; and in the ilex plant, from whose leaves the popular South American beverage yerba mate is prepared"

dr.peperman2 m replied: "i think so. and great question. i never thought about that."

mahirah s replied: "no it does does not exist on anything."

govtagent_2001 replied: "It does not absorb in the muscle tissue it is an important part of metabolism It can activate dopomine in the brain."

Lita replied: "no , only in a few like yerba mate, all colors of teas and coffee beans! most of herbal teas are caffeine free"

My experiment is what is the effect caffeine has on plants thing is I dont know what plant to use for this ex. If you guys have any clue what to use or if you have done this experiment before then please anwer! Thanks!

aestatisa replied: "The type of plant depends on the amount of time and the location that you have for growing them, as well as how you plan to give them caffeine and what you want to use to measure their effect. Are you looking for stunted/increased growth? This site gives experiments for use in elementary school classrooms, so the plants are all easy to grow, grow relatively quickly, and don't need much in the way of special conditions. uses radishes, which can be grown in small styrofoam cups. Expect about 40days for full growth, and because it's a food plant, you can compare the taste on and off caffine. You might try just growing sprouts if you need to get the project done any faster. I've also heard of lettuce being used, as some varieties are also fast growing. Do a web search for "caffeine and plants". Many other people have tried this sort of experiment out. Here is one forum where different people who tried doing this experiment discuss their methods and results: "

Ralph replied: "Use any fast growing plant. Arabidopsis (sp?) is a good choice."

What would your null hypothesis b if you were doing a project that asked, Will caffeine affect a plants growth Please help, its for my science project 2morrow

Dylan H replied: "i have done this before and it does help hem grow."

dg398590 replied: "The null hypothesis for that question or research project would be "That caffeine has no affect on a plants growth)."

Why do plants produce caffeine? Plants that are not even closely related produce the same chemical- why is that? And what is its adaptive significance? It's not a toxin, and it doesn't seem like other animals besides humans are drawn to it. So why do alkaloids kill bugs? And how did caffeine production evolve independently in so many plants (assuming of course that not all of it was independent)?

kumorifox replied: "It is an alkaloid, which either paralyses or kills insects feeding off the plant. It is a natural pesticide, like tannins in trees. Alkaloids are usually nitrogen-based chemicals. Because of their structure, they frequently interact with enzymes, giving them toxic properties. Another example is solanine found in nightshades. I'm not certain why so many plants can form it. It's probably to do with an evolutionary cycle. A common ancestor produced it, and it was found to be efficient in protecting the plant, therefore natural selection made it prevalent. Afterwards, the plants mutated, giving rise to different genera, and creating the plants we know today. Or it could be due to the metabolism of the species. Maybe caffeine production is quite efficient. It would explain why there are so many plant toxins; each plant would have its own type of metabolism and its own type of protection. Caffeine, solanine, atropine, tannins, they are all toxins used to protect the plant. And they would all be produced through different means."

ScRuB replied: "For the plants, caffeine acts as a natural pesticide. It paralyzes and kills insects that attempt to feed on the plants."

Sargonius replied: "It is an alkaloid that acts as a natural pesticide."

What does caffeine contain, to make plants stop growing? why it reduces growth of plants what chemical does it CONTAIN to make plants stop growing

porsche replied: "Caffeine is an alkaloid, it may or may not affect plant growth. Most people that use coffee in their flower pots say they see better growth in their plants. This may be caused by other proprieties in the coffee, which cancel out the caffeine's negative effects. So the only way to know for sure if "caffeine" could cause plants to stop growing would be to use a pure form of caffeine. ~A~"

xtpy792000 replied: "Caffeine is a chemical itself. Its chemical name is trimethylxanthine. I really have never heard that it is bad for plants, but I have heard of coffee grounds used as fertilizer."

How does Caffeine affect plant growth? I was wondering how caffeine affects the growth of plants. Does it cause them to slow down or speed up. I have found some things that said it slows the growth down and some that say speed it up. Which is correct? Thanks for your help.

gardengallivant replied: "If you add used coffee grounds to a plants area for mulch it will compost and fertilize the plant since there is little caffeine to bother the plant. If you apply the caffeine as a concentrated solute it may suppress plant growth. Plants like Camellia sinensis (we make tea from its leaves) produce the caffeine alkaloid as a secondary metabolite in defense against insect herbivory and against other plants encroaching on the camellia's space. So it depends on the plant's sensitivity to caffeine. Some plants make caffeine as a defense while some are injured by it."

Comrado replied: "yes. not sure how."
