PLANTS AND PHOTOSYNTHESIS _ Merson
| Question | Answer |
|---|---|
| Energy that fuels life comes from here | The sun |
| Plants capturing light energy from the sun and using the energy to make food is called..... | Photosynthesis |
| This is the food produced by plants | Glucose (sugar) |
| Glucose is a type of _____ | Sugar |
| Organisms, such as plants, that make their own food are called______ | Producers |
| When glucose is broken down, with the use of oxygen, its energy can be changed into a form that we can use. This is called____ | Cellular Respiration |
| This is the food from photosynthesis that becomes a source of energy for consumers. | Glucose (sugar) |
| An organism that does not make its own food, and eats other organisms for energy. | Consumer |
| Plants grow towards the light. This is called: | Phototropism |
| Plant roots will grow in the direction of gravity. This is called: | Geotropism (or gravitropism) |
| Plants respond to touch, and will curl around supports. This is called: | Thigmotropism |
| Temperature is measured by what instrument? | Thermometer |
| Sunlight intensity is measured by what instrument? | Light meter |
| Humidity is measured by what instrument? | hygrometer |
| What are three major characteristics of PLANT cells which are different from animal cells. | Plant cells: large vacuole for water storage, chloroplasts, and hard outer cell wall for structure and strength |
| The ORGANS of a plant | Roots, Stems, Leaves |
| The underground organ in plants that absorb water and minerals and anchors the plant into the ground. | Roots |
| The supporting structure that carries water and nutrients between roots and leaves | Stems |
| Main site for photosynthesis in plants | Leaves |
| Vascular tissue that carries water UP from roots to plant parts | Xylem |
| Vascular tissue that transports nutrients and sugars DOWN produced by photosynthesis. | Phloem |
| The SEED BEARING female organ of the plant | Pistil |
| The male part of the flower | Stamen |
| The male gametophyte (sperm) | Pollen |
| What THREE things do plants need for photosynthesis? | Carbon Dioxide, Water, Light |
| What TWO things do plants make in photosynthesis? | Glucose (sugar) and oxygen |
| Openings on the bottom of leaves that take in CO2, and let out O2 | Stomata |
| Plant cells SWELL UP and become rigid to store water. This is called: | Turgor Pressure |
| Why do plants wilt? | Lack of water in cells. No turgor pressure. |
| The evaporation of water through the stoma (holes) in plants | Transpiration |
| When a seed begins to 'sprout', and grow roots and exert force into soil. | Germination |
| Period when a plant's life is temporarily stopped to conserve energy | Dormancy |
| Air pressure is measured with what instrument? | Barometer |
| What is the element of life? Once living and living things are chiefly made of this! | Carbon |
| The pushing of the root into the ground in germination is like a simple machine. Which one would it be? | Wedge |
| An example of plant tissue | Zylem |
| A plant that doesn't have enough turgor pressure will: | Wilt |
| The structure in the leaf where photosynthesis takes place | Chloroplast |
| The green pigment in chloroplasts that traps sunlight | Chlorophyll |
| Pigment is a: | Color |
