    Which of the following is a technique by which plants get rid of waste material?

    I. Storing as gum and resin

    II. Removed in the falling leaves

    A Both I and II Correct Answer Incorrect Answer
    B Only I Correct Answer Incorrect Answer
    C Neither I nor II Correct Answer Incorrect Answer
    D Only II Correct Answer Incorrect Answer

    Solution

    In a plant waste materials are often stored in old xylem in the form of gums and resins. Excessive leaf matter on your lawn going into winter is bad for several reasons. First, it will smother the grass and if not removed very soon in the spring it will inhibit growth. Second, it can promote the snow mold diseases. And finally, turf damage from critters (voles, mice) can be more extensive in the spring.
