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 |
