Biology Module 15
Kingdom Plantae: Physiology and Reproduction
| Question | Answer |
|---|---|
| Physiology | The Study of life processes in an organism |
| Four processes of water | Photosynthesis, turgor pressure, hydrolysis, and transport |
| Nastic movement | A plant's response to a stimulus such that the direction of the response is preprogrammed and not dependent of the direction of the stimulus |
| Inorganic components of soil | Gravel, sand, silt, and clay |
| Pore space | Spaces in the soil that determine how much water and air the soil can hold |
| Loam | A mixture of gravel, sand, silt, clay, and organic matter |
| Cohesion | The phenomenon that occurs when individual molecules are so strongly attracted to each other that they tend to stay together, even when exposed to tension |
| Translocation | The process by which organic substances move through the phloem of a plant. |
| Hormones | Chemicals that circulate throughout multicellular organisms, regulating cellular processes by interacting with specifically targeted cells. |
| Auxins | First group of plant hormones discovered. Considered the driving force in phototropism, gravitropism, and thigmotropism |
| Phototropism | A growth response to light |
| Gravitropism | A growth response to gravity |
| Thigmotropism | A growth response to touch |
| Perfect Flowers | Flowers with both stamens and carpels |
| Imperfect flowers | Flowers with either stamens or carpels, but not both |
| Pollination | The transfer of pollen grains from the anther to the carpel in flowering plants |
| Double fertilizatino | A fertilization process that requires two sperm to fuse with two other cells |
| Seed | An ovule with a protective coating, encasing a mature plant embryo and a nutrient source |
| Fruit | A mature ovary that contains a seed or seeds |
| Aggregate fruit | Several separate ovaries of a single flower which ripen individually |
| Multiple fruit | Several ovaries from separate flowers which ripen fused together |
| Pod | Single-chambered ovary with more than one see, opens along its side when ripe |
| Capsule | Multiple-chambered ovary, each with many seeds |
| Samara | Fruit with thin wings |
| Nut | Thinck, hard, woody ovary wall enclosing a single seed |
| Grain | Ovary wall fastened to a single seed |
| Pome | Fleshy portion develops from receptacle, ovary forms leather core with seeds inside |
| Drupe | Ovary forms hard covering around seed and encloses that covering in fleshy tissue |
| Berry | Thin-skinned fruit with ovary divided in sections that contain the seeds |
| Modified berry | Like, a berry, but with a thick tough skin |
| Radicle | Sprouts out of the seed |
| Hypocotyl | Begins to develop into the stem of the plant |
| Epicotyl | Form from the top portion of the embryo |
