| Question | Answer |
|---|---|
| the thin outer layer of cells | Epidermis |
| moves water and minerals to other parts of a plant | Xylem |
| carries sugars made in the leaves throughout the plant | Phloem |
| small holes that water and gases pass in and out of the plant through | Stoma |
| Some plants have one large root called a ______ with many roots growing out of it. | taproot |
| __________ are taproots that store extra _______ made by the plant. | Carrots food |
| During photosythesis plants use _____________ to make ____and ____ | light energy from the sun, carbon dioxide form air, and water glucose and oxygen |
| waxy layer that may cover a leaf and slow water loss | cuticle |
| A motchondria releases_______ and is called the _____of a cell. | energy powerhouse |
| Carrots are roots that ________ | store water |
| Describe two 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 throughout the plant. |
| Plants with stems that are ______and easy to___ are called _____ | green bend Herbaceous |
| process through which plants make glucose | Photosynthesis |
| process by which cells break down glucose with the release of energy | cellular respiration |
| Describe the carbon dioxide-oxygen and explain how it benefits both plants and animals. | Photosynthesis uses the sun, carbon dioxide, and water to make glucose and oxygen.Cellular respiration sues oxygen to break down glucose which provides energy for the plant. Animals exhale carbon dioxide whcih providesthe plant with what it needs to make |
| plant behavior caused by growth toward or way form something in the environment. | Tropism |
| Some seed plants called _____ produce flowers. | angiosperms |
| Most seeds develop into ______. | fruit |
| After fertilization, the female cone ______________. | closes up and seeds grow within it. |
| Compare and contrast a spore and a seed. | Spores contain a single cell that grows into a new plant and a seed contains a multicellular embryo t hat develops into a new plant. |
| How does the environment 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 environment isn't right seeds won't germinate and the embryo stays inside the seed. |
| Plant behaviors can result from______. | chemicals plants make. |
| Name three examples of tropism | Gravitropism is a plants response to gravity to which roots grow down and stems grow out. Phototropism is a response to light in which stems bend toward light and bend away form light. Thigmotromism is a response to touch. Some plants grow toward the su |
