Plants IB Topic 9
| Question | Answer |
|---|---|
| abiotic factors | non-living chemical and physical parts of the environment that affect living organisms and the function of ecoyststems |
| apoplastic movement | it is the movement in the free diffusional space outside the plasma membrane |
| germination | the process by which a plant grows from a seed |
| gravitropism | turning or growth movement by a plant or fungus in response to gravity |
| halophyte | a plant adapted to growing in saline conditions |
| micropropagation | the propagation of plants by growing plantlets in tissue culture and then planting them out |
| mutualism | mutualism |
| phototropism | the orientation of a plant or other organisms in response to light, either towards the source of light (positive) or away from it (negative) |
| Pollination | the carrying of pollen grains (the male sex cells in plants) to the female sex cells for fertilization |
| potometer | a device used for measuring the rate of water uptake of a leafy plant shoot |
| seed dispersal | movement or transport of seeds away from the parent plant sink |
| sink | recieves or stores energy for the plant (roots) |
| source | sends energy for the plant (leaves) |
| symplastic movement | the diffusion of water on the inner side of the plasma membrane |
| translocation | when the sap is pumped into the companion cell and water moves by osmosis |
| amylase | an enzyme, found chiefly in saliva and pancreatic fluid, that converts starch and glycogen into simple sugars. |
| auxin | a plant hormone that causes the elongation of cells in shoots and is involved in regulating plant growth. |
| cytokinins | Another term for Kinin. A compound that promotes cell division and inhibits aging in plants |
| gibberellin | any of a group of plant hormones that stimulate stem elongation, germination, and flowering. |
| IAA | Indole-3-acetic acid is the most common, naturally-occurring, plant hormone of the auxin class. |
| lignin/ lignified | a complex organic polymer deposited in the cell walls of many plants, making them rigid and woody. |
| maltose/ sucrose/glucose | Starch creates maltos/sucrose and glucose to give energy to germinating plants |
| PFR | When Pr absorbs red light, it is converted to the Pfr form. Absorbs at a peak of 666 nm |
| PR | When Pfr absorbs far red light, it is converted to the Pr form Absorbs at a peak of 730 nm |
| anther | where pollen is produced |
| apical meristem | primary meristem tissue with undifferentiated cell s |
| cambium | responsible for secondary growth of stems and roots |
| casparian strip | regulates water and mineral uptake by the roots |
| companion cells | regulates the flow of nutrients through the tubes |
| cortex | storage of photosynthetic products; active in the uptake of water and minerals |
| cotyledon | usually becomes the embryonic first leaves of a seedling |
| dicotyledon | plants with two initial cotyledons (seed leaf) |
| epidermis | protect underlying cells, also allows sunlight to pass through the chloroplast |
| fungus hyphae | Aids plants in nutrient and water absorption |
| guard cells | regulate rate of transportation by opening and closing stomata |
| micropyle | refers to any opening in an ovule's outer layer. This opening allows pollen to fertilize the plant |
| monocotyledon | one seed leaves which develop from the plumule |
| ovary | contains the ovules which has the egg cell inside. After fertilization the ovary becomes a fruit |
| phloem | vascular tissue that distributes organic molecules mainly manufactured in leaves |
| pollen tube | tube that grows towards ovules after pollen is spread on the stigma |
| procambium | cambium in young stage, will form vacular tissue |
| protoderm | early stage, will develop into epidermis |
| reproductive structures | flowers (pistil is the female organ, the stamen is the male organ) |
| root hair | Tube-like extension of plant roots that absorbs water and minerals, increase surface area |
| sepal | Parts that surround and protect the bud |
| sieve tube | transport carbohydrates e.g. sucrose in plant |
| stem | support the leaves, conduct water and mineral to leaves |
| roots | part of plant for support the plant, and absorb water and nutrients |
| stigma | female part that receives pollen |
| stomata | control tradeoff for plant, alloe CO2 in but let water escape |
| style | assist with fertilization by being location where pollen tube travel sperm cell to egg |
| testa | block entrance of water, hinder gas exchange so embryo lack oxygen aka the seed coat |
| tracheids | found in xylem with vessel elements for transport of water and mineral salts |
| tubers | modified stems for nutrient storage, nutrient sinks |
| vascular bundle | transport system, including supporting and protective tissues |
| vegetative structures | structural modification of stem |
| xylem vessels | vascular system element that transport water and dissolved ions up to stems and leaves. |
| meristem tissue | the tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place. |
