Plants-Part 2 of 2

    1. There are two kinds of plants that form seeds: _______________________plants and
        _______________________plants.
    2. _______________________ are found in the cones of cone-bearing plants and the fruit of
        flowering plants.
    3. _______________________are reproductive structures.
    4. A _______________________is the part of a flowering plant that contains and protects the
        seeds.
    5. Flowers have parts that work together to make seeds: _______________________,
        _______________________, and _______________________
    6. The stamen makes _______________________.
    7. The _______________________collects the pollen. The bottom of the pistil is the ovary where
        _______________________ form. It is the central structure of the flower surrounds by the
        stamens, the petals, and the sepals.
    8. _______________________are leaf like petals at the base of a flower.
    9. Seeds form after a flower is _______________________.
    10. _______________________ happens when pollen is carried from a stamen to a pistil by wind or
        animals.
    11. A seed is made up of a young plant, called an _______________________.
    12. When the seed has met its needs it germinates, or _______________________.
    13. The seeds of a pine tree (a cone-bearing plant) form between the _______________________of
        its cones.
    14. Not all plants grow from _______________________.
    15. Some plants grow from a piece of stem put into water. New roots grow from the bottom of the
        stem. The new stem with roots is planted in soil.
    16. Potatoes are _______________________, or swollen underground stems. Tubers are often dug
        up to eat.
    17. Plants have many adaptations that help them survive in different environments.
             a. The _______________________is an unusual plant because it gets nutrients from
                 insects that lands on its leaves. The leaves shut and traps the insect inside.
             b. During the winter months, there is less daylight for photosynthesis. Therefore, some
                 trees enter a state of _______________________, or lower activity, until spring.
             c. Cacti have roots that grow near the surface because it is easier to collect
                 _______________________in their very dry climate.

Plants-Part 2 of 2

    1.    There are two kinds of plants that form seeds: cone-bearing plants and flowering plants.
    2.    Seeds are found in the cones of cone-bearing plants and the fruit of flowering plants.
    3.    Flowers are reproductive structures.
    4.    A fruit is the part of a flowering plant that contains and protects the seeds.
    5.    Flowers have parts that work together to make seeds: stamen, pistil, and sepal
    6.    The stamen makes pollen.
    7.    The pistil collects the pollen. The bottom of the pistil is the ovary where seeds form. It is the
          central structure of the flower surrounds by the stamens, the petals, and the sepals.
    8.    Sepals are leaf like petals at the base of a flower.
    9.    Seeds form after a flower is pollinated.
    10.   Pollination happens when pollen is carried from a stamen to a pistil by wind or animals.
    11.   A seed is made up of a young plant, called an embryo.
    12.   When the seed has met its needs it germinates, or sprouts.
    13.   The seeds of a pine tree (a cone-bearing plant) form between the scales of its cones.
    14.   Not all plants grow from seeds.
    15.   Some plants grow from a piece of stem put into water. New roots grow from the bottom of the
          stem. The new stem with roots is planted in soil.
    16.   Potatoes are tubers, or swollen underground stems. Tubers are often dug up to eat.
    17.   Plants have many adaptations that help them survive in different environments.
               a. The Venus Fly Trap is an unusual plant because it gets nutrients from insects that lands
                    on its leaves. The leaves shut and traps the insect inside.
               b. During the winter months, there is less daylight for photosynthesis. Therefore, some
                    trees enter a state of dormancy, or lower activity, until spring.
               c. Cacti have roots that grow near the surface because it is easier to collect rain water in
                    their very dry climate.
