  1. Ferns, Club mosses and horsetails are vascular plants.

    TRUE
    FALSE
    TRUE
  2. Which tend to grow taller, a vascular or non-vascular plant?
    A vascular plant tends to grow taller.
  3. What does a vascular plant do that a non-vascular plant cannot do?
    A vascular plant can use vessels to transport water and nutrients to the cells of the plants. A non-vascular plant does not have vessels and cannot easily transport water and nutrients.
  4. How do ferns, club mosses, and horsetails reproduce?

    A. conjugation
    B. seeds
    C. sprouts
    D. spores
    D. spores
    (this multiple choice question has been scrambled)
  5. What type of environment do the spores of ferns, club mosses, and horsetails need for fertilization occur?

    a. a moist environment
    b. a dry environment
    c. a windy environment
    d. a shady environment
    e. a sunny environment
    a
  6. What type of plants have true stems, roots, and leaves?

    a. Vascular plants
    b. Non-vascular plants
    a.
  7. Which of the following is NOT one of the major food sources for the people on Earth today?

    A. rice
    B. potatoes
    C. wheat
    D. apples
    E. corn
    D. apples
    (this multiple choice question has been scrambled)
  8. A true moss is a vascular plant.

    TRUE
    FALSE
    FALSE

    True mosses are NON-VASCULAR plants. A club moss is a vascular plant and not truly a moss.
  9. By the year 2050, it is predicted that the population of the world will be __________ people.

    A. 2 billion
    B. 6 billion

    (You will need to know the answers.)
    • a.) These crops grow only in certain climates
    • b.) The size and structure of these plants limit how much food they can produce.
  11. What are scientists doing to produce plants that can grow in a wider range of climates?

    A. They are making plants larger
    B. They are making climate changes to allow the plants to grow in new places
    C. They are making plants smaller
    D. They are genetically engineering the plants
    D. They are genetically engineering the plants
    (this multiple choice question has been scrambled)
  12. In addition to making plants that can grow in a wider variety of climates through genetic engineering, scientists are also making plants that are _______________.

    C. Ferti-Farming
    D. Seed bed farming
    B. Precision farming
    (this multiple choice question has been scrambled)
  14. What two technological devices can farmers use to help them with precision farming?

    (You need to know the answers.)
    • satellite images
    • computer analysis
  15. Precision farming does three main things for the farners.
    What are they?
    • It increases crop yields
    • It saves time
    • It saves money
  16. Reducing the use of fertilizer can help to prevent ___________ from damaging bodies of water.

    B. runoff
    C. carp
    D. cattle
    E. catfish
    A. algal blooms
    (this multiple choice question has been scrambled)

    E. hydro-fertilization
    C. hydroponics
    (this multiple choice question has been scrambled)
  18. Is the use of hydroponics expensive or non-expensive?
    expensive
