| Question | Answer |
|---|---|
| Photosynthesis | The chemical process whereby plants produce food inside their leaves |
| Tropism | The growth of a plant in response to a condition in its environment |
| Fertilization | The process of transferring pollen from the stamen to the pistil |
| Chlorophyll | The pigment or coloring that gives plants their green color |
| Bract | Serve the same function as the petal, to attract insects to the flower, but have a much different structure |
| Stomata | Pores on the underside of the leaf |
| Glucose | The food plants need to live |
| Cuticle | The waxy covering that coats the skin of the leaf and prevents water from escaping |
| Guard Cells | Each Stoma is opened and closed by two guard cells that surround the tiny opening |
| Cellulose | A tough, fibrous material that forms a strong cell wall around each plant cell |
| Chloroplasts | As sunlight enters the leaf, some of its energy is absorbed by tiny packages of chlorophyll called chloroplasts |
| Embryo | Miniature, undeveloped plant made up of a tiny shoot |
| Botanist | A scientist who studies plants |
| Shoot System | The part of the plant visible, above ground |
| Root System | The part of the plant located under ground |
| Root Cap | A layer of tough protective cells covering the root |
| Taproot | A particularly deep root |
| Root hair | Tiny projections near the end of the root |
| Pistil | A long tube in the middle of a flower, surrouned by petals |
| Petal | Attract insects to the flower |
| Leaf | Carries out photosynthesis |
| Flower | Allows plants to reproduce |
| Root | Absorbs water and minerals for the plant |
| Stem | Allows liquid to move up and down the plant |
| Cell Wall | Protects the stem |
| Ovary | Hold the seeds, becomes fruit |
| Stamen | Makes and hold the pollen |
| Veins | Transport liquids and reinforces the leaf's structure |
| Pitcher Plant | Attracts insects with its bright colors and its aroma of honey like nectar |
| Day Lily | Long, narrow leaves and orange, trumpet like flower that lasts no longer than a day |
| Venue Flytrap | Has tiny trigger hairs that slam the two leaves together on insects that crawl into it |
| Sundew | Has dew drops that cause inssects to get stuck |
| Bladderwort | Uses water containing leaves to trap insects |
| Grasses | Small flowers, two-part leaf, reproduces without flowers (ex.sugar cane) |
| Pea Family | Has five petals (1 large and 4 small), and fruits grow in the shape of pods (ex.legumes) |
| Lily Family | Petals grow in multiples of 3, grow from bulbs (ex.day lily) |
| Rose Family | Petals grow in multiples of five, includes apples and cherries |
| Composite Family | Largest flowering family, two types of flowers make up the one flower (ex.Daisy) |
| Carolus Linnaeus | One of the first people to classify plants and animals |
| George Washington Carver |
