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 |
