plants produce toxic

Post by cathy00012345 » Thu Feb 23, 2006 7:53 am

Plant cells produce many substances that could be toxic to the cell. Describe how a cell could protect itself from its own toxic products. Why would a plant produce a toxic product such as ricin?

Plz help!!! :lol:

many dangerous substances like enzymes are stored in the lysosomes, very useful organnelles that consume trash and foreign objects with the enzmes they carry

Depending on how they pollinate they might produce toxic substances to prevent from being eaten.

thats very true a defensive mechanism!
i neva wud've thought of it that way, there are also animals that produce dangerous substances for self defence like certain frogs produe LSD that makes thier predators see things that rent really there so the frog can simply walk away whilst the predator hallucinates (mmm prob spelt that wrong but hey)

True. The most commonly known substance produced by plants to prevent herbivores from eating them is latex. Latex, secreted by special glands that resemble xylem tubes, is toxic to any animal that might eat it, thus acting as a great defense mechanism.

Some animals, like some monkeys, have evolved ways to go round this mechanism. Their body can tolerate a higher amount of the stuff, but also they only eat the leaf stalk from leaves, which contains very few latex...
In the evolutionary arms race, it's the survival of the most creative organism.
