Science Unit 8 Flash Cards - Plants
| Term | Definition |
|---|---|
| Geotropism | plants response to Earth's gravity, roots grow towards the source of gravity (positive) shoots grow away (negative) |
| Tugor Pressure | Plants have water in their cell vacoules, the water pushes (force) on the cell membrane and wall creating a type of pressure which makes the cell stiff or rigid |
| Phototropism | Plant growth in response to a light source, plant bends to grow towards the sun |
| Equation for Photosynthesis | 6 water + 6 CO2 + sunlight + sugar/glucose (C6+H12+O6 + 6 O2 |
| Pholem | Vessels in the stem to transport food |
| Thygmotropism | Plant growth in response to touch. Plant wraps around an object it comes in contact with. |
| Autotrophs | Plants which is an organism that can produce their own energy through chemical reaction. |
| Xylem | Vessels in the stem to transport water. |
| Photosynthesis | The process plants use to produce sugar from sunlight. |
| Radiant Energy | Chemical energy transformed from the sun. |
| Chloroplast | Organelle found in the plant cells in the leaves of green plants which help to produce food for the plant (in form of sugar) during photosynthesis. |
| Tropism | Plant's growth response to a stimulus |
| Hydrotropism | Plant growth in response to water. Plants' roots grows toward a water source. |
| Chlorophyll | Green pigment in leaves that captures sunlight. |
| Carbon Dioxide | Waste product of animals, needed by plants for photosynthesis. |
| Glucose | Plant food made during photosynthesis |
| Stimulus | Something that causes a reaction/response; internal or external. |
| Chemical Energy | Energy made by plants during photosynthesis |
