    Why is the ability to respond quickly essential for the wild tobacco plant?

    <p>The wild tobacco plant's seeds need wildfire to kick-start their growth, and they can wait for hundreds of years for that to happen.</p> Signup and view all the answers

    How does the wild tobacco plant defend itself against herbivores?

    <p>The wild tobacco plant ramps up the production of nicotine, a toxin that poisons any organism with muscle. It also releases chemical messages that attract predators of the herbivores attacking it.</p> Signup and view all the answers

    What is the purpose of the wild tobacco plant emitting certain smells?

    <p>to inform predators, particularly ground foraging predators, that the plant is offering food for caterpillars but the caterpillar will be tagged for predation</p> Signup and view all the answers

    What is the feeding habit of the daughter vine and how does it obtain its food?

    <p>The daughter vine is a parasitic plant that lives off a host plant. It pierces the stem of the host plant and drains it of its life-giving sap.</p> Signup and view all the answers

    How does the daughter vine choose its host plant?

    <p>The daughter vine is able to detect its host plant by sniffing out the chemical odor released by the leaves of potential hosts.</p> Signup and view all the answers

    What is the purpose of the chemical SOS released by plants when they're under attack?

    <p>The chemical SOS acts as a cry for help, attracting insects that eat the insects that are attacking the plants.</p> Signup and view all the answers

    What is one of the advantages that plants have in defending themselves against predators?

    <p>Plants have evolved nifty methods of self-defense, such as releasing chemical signals and attracting predator insects, since they cannot escape or physically defend themselves.</p> Signup and view all the answers
