Question | Answer |
autotrophic nutrition | self feeders; make their own food |
photosynthesis | – process of turning inorganic substances into organic substances;
CO2 + H2O + light --> glucose + O2 |
chloroplasts | organelles in plants that perform photosynthesis |
chlorophyll | pigment in the choloplast that give the green color |
light reaction | break down of water portion of photosynthesis with light |
dark reaction | formation of glucose part of photosynthesis without light |
stomates | openings in undersides of leaves to allow gas exchange |
guard cells | cells that control the opening & closing of the stomates |
epidermis | upper layer of the leaf |
xylem | vascular structure that carries materials from root hairs to leaves |
phloem | vascular structure that carries nutrients from leaves down through plant |
root hairs | fine vascular structures that increase surface area for absorption of nutrients |
cuticle | outermost layer of epidermis; prevents water loss |
blade | flat part of leaf that captures sunlight |
petiole | stemlike part of leaf that attaches it to the stem of the plant |
axil | junction of the petiole to the stem of the plant |
stipules | small leafs at the axil |
transpirational pull | column of water held together by cohesive forces and pulled out by evaporation |
capillary action | water tends to rise in tubes of narrow diameter, allowing for a small amount of upward transport of water |
auxins | plant hormones |
tropisms | unequal distribution of auxins caused by specific factors resulting in growth responses |
phototropism | response of plant to light |
geotropism | response of plant to gravity |
stamen | male reproductive part of flower |
anther | top part of stamen where pollen forms by meiosis |
filament | stalk of stamen that holds up anther |
pistil | female reproductive part of flower |
stigma | top part of pistil where pollen is deposited |
style | stalk within which the pollen tube forms in the pistil |
ovary | base of the pistil, contains the ovule where female gametes produced |
petals | colored leaves that attract insects |
