Plant Science Flashcards
series of chemical reactions convert food molecules into ATP
Cellular respiration
usable power
energy
diffusion of water
osmosis
plants reaction to the number of hours in darkness
Photoperiodism
any change in the environment that causes organisms to respond
stimulus
layer of plant tissue that produces new vascular tissue and grows between xylem and phloem
cambium
opening in a leaf
stoma
group of cells in an organism
tissue
carries water and dissolved NUTRIENS from roots to stem and leaves
xylem
carries dissolved SUGARS
phloem
forms from flower and has one or more seeds
fruit
pollen grain lands on FEMALE reproductive structure (says pollen grain twice)
Pollination
structure that forms from tissue in the MALE reproductive structure
pollen grain
haploid generation of a plant
spore
leaf or fern
frond
series of chemical reaction that converts light energy into water and carbon dioxide into glucose and give off oxygen
photosynthesis
substance that acts as a chemical messenger in plants
Plant Hormone
response that results in plant growth toward or away from a stimulus
tropism
FEMALE part of a plant
pistil
MALE part of a plant
Stamen
Anchors seedless plant to surface
Rhizoid
structure made of an embryo
seed
Found at the base CONTAINS OVULES
Ovary
haploid egg develops
Ovule
composed of TUBELIKE cells
vascular tissue
organic compounds made up of CHAINS of glucose molecules
cellulose
to carry something or something
transport
makes it’s own food
producer
waxy protective layer
cuticle
life cycle of a plant
generation
