Botany Unit 6
| Question | Answer |
|---|---|
| Enhanced | Improve the quality of production |
| Come true to seed | Offspring looks just like parent |
| Egg | Female sex cell |
| Flat | Wooden box with slotted bottom used to start seedlings |
| Seed Coat | Outer covering of the seed |
| Tissue Culture | New method for rapidly reproducing plants using terminal bud tissue |
| Hybrid | Offspring of 2 different varieties of 1 plant that possess certain characteristics of each plant |
| Seedling | Young plant that has been germinated for several days |
| Pollen | Male sex cell in plants |
| Hardening off | Gradually making growing conditions tougher |
| Cotyledons | First leaves to appear on a plant; seed leaf |
| Embryo | New plant that develops after germination |
| Propagation | To increase in number |
| Endosperm | The food supply for the young developing seedling |
| Peat moss | Partially decomposed vegetation that as been under water |
| Sphagnum | Material formed from decaying plants |
| Jiffy mix | Composed of equal parts of shredded sphagnum moss, peat, fine grade vermiculite and enough nutrients to sustain initial plant growth |
| Vermiculite | Light mineral with a neutral pH used to increase the moisture holding capacity of media |
| Sand | More porous than soil |
| Soil | Should be loam composed |
| Perlite | Grey white material of volcanic origin used to improve aeration of the media |
| Direct seeding | Planting seeds in a permanent growing site |
| Why do we harden off plants? | To prepare plants for transplanting |
| How do you harden off plants? | Gradually subject plants to more difficult growing conditions by withholding water and decreasing temperature |
| Indirect seeding | Seeds are sown in a place separate from where the plants will eventually grow to maturity |
| Conditions necessary for germination | Temperature of no less than 65 degrees, humidity, light |
| Two enhancement (primed) treatments | Soak |
| Most common way plants propagate | by seeds |
| What conditions are needed for proper propagation? | Right temp., light, medium, and moisture |
| Scarification | In intentional damage or removal of the seed coat |
| Stratification | Process of pretreating seeds to simulate natural conditions that a seed must endure before germination |
| Heat treatment | Seeds exposed to high heat for a very brief moment |
| Chemical treatment | Seed is immersed in sulphuric acid for a few minutes to break dormancy |
| Special Treatment | Alternate wetting and drying of seed |
| Flash burn | |
| Parts of a seed | Embryo, food supply - Endospern, Oc |
| Purpose of seed coat | Protects embryonic plant |
| Purpose of endosperm | Food storage tissue that nourishes the embryonic plant during germination |
| Process of germination | Seed absorbs water, seeds protein activated, radical (root) emerges, plumule or embryonic shoot emerges, leaf forms and food production begins |
