seed germination
process where a seed grows into a plant
phototropism
a plant response to light
geotropism
a plant response to gravity
thigmotropism
a plant response touch
xylem
transportation of water from the roots upward to all parts of the plant
phloem
transportation of glucose from the leaves down to the rots of the plant
cuticle
waxy, protective layer that covers plants and helps prevent water loss
guard cells
pair of cells that surround stomata and control their opening and closing
nonvascular plants
plant that doesn't have specialized tube-like tissue for moving food and water throughout the plant
rhizoid
threadlike structures that anchor nonvascular plants where they grow
stomata
tiny openings in leaves through which gases enter and exit (CO2, O2, water vapor)
vascular plant
plant that has specialized, tube like tissue for moving food and water
photosynthesis
process in which plants make food/sugar
positive geotropism
growth of a plant down towards the center of the earth-down with gravity
negative geotropism
growth of a plant upwards from the center of the earth-opposite from the pull of gravity-stems grow up.
positive phototropism
growing toward the source of light
negative phototropism
growing away from the light
turgor pressure
pressure of water against the inside wall of a plant cell.
vacuole
location of water storage in the cell
radiant energy
sun
chemical energy
food
Hydrotropism
a plants growth response to water; plant grows towards the water
Photosynthesis Reactants
carbon dioxide, water, and sunlight
Photosynthesis Products
glucose and oxygen
Photosynthesis Chemical Equation
CO2+H2O+ sunlinght --> C6H12O6 + O2
chloroplast
An organelle found in plant cells where photosynthesis occurs
