xylem moves water and minerals to other parts of the plant
epidermis the thin outer layer of the cell
phloem carries sugars made in leaves throughout the plant
stoma small holes that water and gases pass in and out of the plant through
gaurd 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 ________ with many roots growing out from it taproot
carrots are taproots that store extra _________ made by the plant food
carrots are _________ that store water roots
describe two functions of stems in flowering plants stems provide suport for the plant as it grows. The stems also have zylem and phloem, which move water, minerals, and glucose throughout the plant.
plants with stemsthat are green and easy to bend are called_________________ Herbaceous
______________opens and closes a leafs stoma Xylem
photosynthesis process through which plants make glucose
cellular respiration process by which cells breakdown glucose with the release of energy
during _________________, plants use light energy from the sun, carbon dioxide from the air, and water to make glucose and oxygen photosynthesis
culticle waxy layer that makcover a leaf and slow water loss
mitochondrion releases energyand is called the powerhouse of a cell
carbon dioxide- oxygen cycle and how benefit plants and animals Photosynthesis uses sun, carbn dioxd, & water to make glucose & oxygn. Cellular respiratn uses oxygn to break down glucose. = provides energy for plant. Animals exhale carbn dioxd which provides the plant with what needed to produce glucose & oxygn. Anim
how does carbon dioxide-oxygen cycle benefit both plants and animals? Photosynthesis and cellular respiration provides energy for the plant. Animals exhale carbon dioxide, which provides the plant with what it needs to produce glucose and oxygen. Animals breathe oxygen from the air and use it to burn food for energy. So
tropism plant behavior caused by growth toward or away from something in the environment
some seed plants, called __________________, produse flowers angiosperms
most seeds develop into a _______________ fruit
after _____________, the female cone closes up and seeds grow within it fertilization
Compare & Contrast a spore and a seed Spores contain a single cell that grows in to a new plant and a seedcontains a multicellular embryo that developsinto a new plant.
How does the environment influence the time at which a seed germinates? Seeds need a certian temperature, water, and oxygen. If the environment is not right seeds won't germinate and the embryo stays inside the seed.
plant behavior can result from_____________ the plant makes chemicals
3 examples of tropism 1.gravitropism 2.phototropism 3.thigmotropism
