Is caffeine a defense mechanism for plants?

Though it may seem strange, the purpose of caffeine is not to stimulate the human nervous system (though it is a wonderful side effect) but rather it is produced as a defense mechanism for the plant. Making this compound is a complex process that involves many metabolic steps within the tissues of the plant.

Why do some plants produce caffeine?

Another use of caffeine in coffee plants is to protect itself from competing plants. When the leaves and cherries fall the ground, they release small amounts of caffeine into the soil that can inhibit the growth of other seeds, thus giving their seedlings a competitive advantage.

Does caffeine occur naturally in plants?

Caffeine is an alkaloid occurring naturally in some 60 plant species, of which cocoa beans, kola nuts, tea leaves and coffee beans are the most well-known. Other natural sources of caffeine include yerba maté, guarana berries, guayusa, and the yaupon holly1.

Do all plants have caffeine?

Why do some plants make caffeine? Obviously, not all plants make caffeine, otherwise people would brew their lawn clippings. Only about 60 species of plants in the world are known to make caffeine.

How does caffeine affect the growth of a plant?

Caffeine, a chemical stimulant, increases the biological processes in not only humans but plants as well. Studies involving the use of caffeine on plants have shown that, initially, cell growth rates are stable but soon the caffeine begins to kill or distort these cells, resulting in a dead or stunted plant.

What plants naturally produce caffeine?

Found in more than 60 species of plants across the globe, caffeine comes from the seeds of coffee beans, cacao beans and Kola nuts; the leaves and buds of tea; the leaves of Yerba mate; and in the bark of Yoco. Other natural sources of caffeine include guarana berries, guayusa and the yaupon holly.

Does the source of caffeine matter?

4. Caffeine is not addictive. There is no physical dependency of caffeine – and it doesn’t matter what source of caffeine is consumed (coffee, tea, cola). You might feel dependent on a certain food-source of caffeine, but it is not the caffeine alone.

Does caffeine inhibit plant growth?

How does caffeine work and why do plants produce it?

Caffeine starts out in coffee plants as a precursor compound called xanthosine. The coffee plant makes an enzyme that chops off a dangling arm of atoms from the xanthosine; a second enzyme adds a cluster of atoms at another spot. The plant then uses two additional enzymes to add two additional clusters.
