Plant Needs 5th grade
| Term | Definition |
|---|---|
| plant | an organism that is made up of many cells, makes its own food through photosynthesis, and cannot move; a member of kingdom Plantae |
| producer | an organism that makes its own food through photosynthesis |
| photosynthesis | plants use energy from sunlight to make their own food from water and carbon dioxide. |
| sun | original source of energy for most ecosystems |
| plant needs for photosynthesis | water, carbon dioxide (from air), and sunlight |
| things plants produce during photosynthesis | glucose (food for the plant) and oxygen |
| glucose | food that plants produce during photosynthesis |
| carbon dioxide | Humans and other animals rid themselves of this by exhaling, or breathing out; plants take it in through their leaves for photosynthesis |
| oxygen | humans and other animals breathe this in; plant release this as a waste product through photosynthesis |
| Chloroplast | part of a plant cell where photosynthesis occurs |
| vessels | narrow bundle of tubes within a leaf used to move water and nutrients from the roots to the leaf cells, and nutrients from leaves to the rest of the plant |
| roots | soak up water, vitamins and minerals from the soil so that a plant has plenty of food and nutrients |
| stems | supports the plant so that it stands upright. It has many thin tubes that carry water, minerals and food up from the roots. |
| leaves | make food, or sugar. They also take in carbon dioxide and turn it into oxygen, which is then released into the atmosphere |
| plant cells | are like animal cells but they have a cell wall and contain chlorophyll, which gives the different parts of a plant their green color. |
| respiration | the taking in of oxygen and release of carbon dioxide by humans or other animals |
| carbon cycle | the natural cycling of carbon dioxide and oxygen through the atmosphere |
| chlorophyll | substance that plants need to absorb sunlight |
