Plant Unit Part 1
First 12
| Question | Answer |
|---|---|
| Botany | the study of plants |
| Botanist | a scientist who studies and classifies plants |
| trait | a physical characteristic or behavior that distinguishes one type of organism from another |
| plants | organisms that do not move from location to location and have the ability to make their own food through the process of photosynthesis |
| producers | organisms that make their own food (plants) |
| consumer | organisms that must eat other organisms for their nourishment |
| mosses (bryophytes) | non-vascular plants that grow low to the ground and reproduce with spores |
| fern(pteridophytes) | a seedless vascular plant with roots, stems, and leaves (reproduce w/ spores) |
| gymnosperm (conifer) | a vascular plant whose seeds are not enclosed (they're "naked".) (Seeds form on -female- cones.) (Most are "evergreens") |
| angiosperm | flower bearing plants which produce seeds totally enclosed within a fruit |
| Mosses, Ferns, Conifers, Flowering plants | four groups for classifying plants |
| spore | an asexual reproductie cell with a hard covering (NOTE: spores are produced on mature stalks formed by the fertilization of female egg cells by male sperm cells on the same plant) |
| seed | a mature, fertilized plant ovary made up of a seed coat, one of two cotyledon, and an embryo |
| leaves | the part of the plant in which food is made (may be simple of compound) |
| chlorophyll | a green pigment inside some plant cells which traps the energy of the sun and uses it to produce food for the plant |
| photosynthesis | the process by which plants use water, carbon dioxide, chlorophyll in their leaves, and light energy from the sun to produce their own food (in the form of glucose) and give it off oxygen as waste |
| root | an organ that anchors a plant in the ground and absorbs water and minerals from the soil |
| stem | the part of the plant that supports the leaves and contains the "pipes" or vascular bundles that transport water, food, etc. throughout the plant |
| non-vascular plants (bryophytes) | plants which lack the "pipes" which carry water and nutrients to all parts of the plant (these plants are low to the ground- mosses and liverworts) |
| vascular tissue | plant tissue made up of tubelike cells that carry food, water, and minerals from one part of the plant to another. |
| xylem | vascular tissue that conducts water from the root to the stem and leaves |
| phloem | vascular tissue that conducts food from the leaves to the rest of the plant |
| cotyledon | a food-storing part of a seed that is used by a developing plant until it can produce its own food |
| monocot | an angiosperm with one cotyledon (tulips, most grasses) |
| dicot | an angiosperm with two cotyledon (beans, peanuts) |
| pollination | the transfer of pollen from the male part of a flower to the ovary of a female pistil |
| pollen | the male sex cell of a plant |
| ovary | the female sex cell of a plant |
| germination | the development of a plant embryo into a young plant |
| embryo | a developing, many celled organism |
| vegetative propagation | the starting of new plants by rooting mature plant parts (leaves, roots, cuttings, etc.) in water or soil (spider plant!!!) |
