| Question | Answer |
|---|---|
| Epidermis | The thin outer layer of cells |
| Xylem | Moves water and minerals to other parts of a plant |
| Phloem | carries sugars made in leaves throughout the plant |
| small holes that water and gases pass in and out of the plant through | stoma |
| work together to open and close leaf's stoma | guard cells |
| loss of water from the leaf | transpiration |
| Some plants have one large root called with many roots growing out from it | tap root |
| are taproots that store extra food made by the plant | carrots |
| carrots are roots that store | water |
| Describe 2 functions of stems in flowering plants? | Stems provide support for the plant as it grows. The stems also have xylem and phloem, which move water,minerals, and glucose through out the plant |
| Plants with stems that are green and easy to be bend are called | Herbaceous |
| process in which plants make glucose | Photosynthesis |
| process by which cells break down glucose with the release of energy | cellular respiration |
| During plants use light energy from the sun,carbon dioxide from the air,and water from glucose | photosynthesis |
| waxy layer that may cover a leaf and slow water loss | cuticle |
| plant behavior caused by growth toward or away from something in the enviroment | Tropism |
| Some seed plants called produce flowers | angiosperms |
| most seeds develop into a | fruit |
| After fertilization the crosses up and seeds grow within it | female cone |
| Compare and contrast a sore and a seed | Spores contain a single cell that grows in to a new plant and a seed contains a multicellular embryo that develops into a new plant |
| How does the enviroment influence the time at which a seed germinates?How does this help the seed to survive? | Seeds need a certain temperature, water and oxygen. If the enviroment is not right seeds won't germinate and the embryo stays inside the seed. |
| Plant behaviors can result from the plant make | chemicals |
