| 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 |
