Question | Answer |
---|---|
Epidermis | The thin outer layer of cells |
Moves water and minerals to other parts of the plant | Xylem |
Phloem | carries sugars made in leaves throughout the plant |
Stoma | small holes that water and gasses pass in and out of the plant through |
Guard Cells | work together to open and close a leaf's stoma |
Transpiration | loss of water from the leaf |
Some plants have one large root called a | taproot with many roots growing out from it |
__are taproots that store extra food made by the plant | Carrots |
__are roots that store water | Carrots |
Stems provide support for the plant as it grows. The stems also have __ and __ which move __ __ __ throughout the plant | xylem and pholeum water,minerals, and glucose |
Plants with stems that are green and easy to bend are called__ | herbaceous |
__ opens and closes a leaf's stoma | Guard Cells |
Photosynthesis | process thorough which plants make glucose |
Cellular Respiration | process by which cells break down glucose with the release of energy |
During photosynthesis plants use __ __ __ and __ to make glucose and oxygen. | light energy from the sun,carbon dioxide form the air,and water |
Cuticle | waxy layer that may cover a leaf and slow water loss |
A ___ releases energy and is called the ___ of a cell | mitochondria powerhouse |
Describe photosynthesis and cellular respiration? | Photosynthesis uses the sun, carbon dioxide,and water to make glucose and oxygen. Cellular respiration uses oxygen to break down glucose. This provides energy for the plant. |
Tropism | plant behavior caused by growth toward or away from something in the environment |
Some seeds plants, called ___ produce flowers | angiosperms |
Most seeds develop into a __ | fruit |
After fertilization, the female cone closes up and ___ grows within it. | seeds |
Describe spores? | Spores contain a single cell that grows into a new plant and a seed contains a multicellular embryo that develops into a new plant |
How do seeds survive? | Seeds need a certain temperature,water,and oxygen. If the environment is not right seeds wont germinate and the embryo stays inside the seed. |
plant behaviors can result from __ the plants make | chemicals |
Describe 3 examples of tropism? | Gravitropism is a plants response to gravity to which roots grow down and stems grow up. Photo tropism is a response to light and in which stems bend tword light and roots bend away from light. Thigmotropism is plants grow twrod the surface they touch. |
