|
Carotenoids
|
accessory pigments a plant uses in the process of photosynthesis that can absorb wave lengths that chlorophyll cannot
|
|
|
Chlorophyll
|
green pigment found in the membrane of the thylakoid of a chloroplast that absorbs light for the process of photosynthesis
|
|
|
Thylakoid
|
the membranous sac in a chloroplast; the membrane contains pigments/photosystems
|
|
|
Granum
|
a stack of thylakoids
|
|
|
Radical
|
the part of the embryonic plant (seed) that will become the root
|
|
|
Plumule
|
the part of the embryonic plant (seed) that will become the leaves
|
|
|
Water Potential
|
the potential energy of water
|
|
|
Turgor Pressure
|
water pressure exerted by a plant due to the cell membrane pressing against the cell wall
|
|
|
Cohesion
|
the tendancy of water molecules to stick together due to hydrogen bonding
|
|
|
Transpiration
|
the evaporation of water through the stomata of the leaves
|
|
|
Photosystem
|
a group of chlorophyll molecules in the membrane of a thylakoid that absorbs solar/light energy for photosynthesis
|
|
|
Chemiosmosis
|
the flow of hydrogen atoms down their electrochemical gradient that provides the energy for ATP synthase to produce ATP molecules
|
|
|
Tropism
|
plant responses in which they grow toward or away from a directional stimulus
|
|
|
Hypocotyls
|
the part of the embryonic plant (seed) that will become the stem
|
|
|
Phototrophism
|
plant growth responds to light; toward or away
|
|
|
Thigmotrophism
|
plant growth responds to touch; toward or away
|
|
|
Nastic Movements
|
plant responses that are independent of a stimulus
|
|
|
Photoperiodism
|
the physiological responce of a plant due to the length of day or night
|
