Sexual Reproduction :
-seeds produced
-daughter plants show variations
-variation result of meiosis |
|
|
Term
|
Definition
-No Seeds
-Daughter Plants Identical
-Mitosis: Identical Daughter Cells
Available from : Bulblets from bulbs - runners - suckers - cuttings |
|
|
Term
| Asexual Reproduction also called Vegetative or clonal propogation |
|
Definition
-plants have only one parent
-new plants are clones of parents
-seeds can have two parents but not always |
|

Definition
| each plant cell has all the genetic info needed to produce a complete plant |
|
|
Term
|
Definition
| The ability of a cell to change i's fate - root cell to produce shoot cells- stem cells to produce root cells |

Term
| advantage to asexual reproduction 1 |
|
Definition
-only way to maintain a unique characteristic of a particular plant
-cultivars can only be propagated asexually
(October glory red maple) |

|
Term
| advantage to asexual reproduction 2 |
|
Definition
| some plant species have so much genetic variability that seed reproduction results to inferior plants ( apples, pears, plum, peach, and rassberry) |
|
|
Term
| advantage to asexual reproduction 3 |
|
Definition
| some plant species produce few seeds or seed hard to germinate (n some Verbanums, and American holly |

Definition
| produce many plants more quickly than by seed |

|
Term
| Disadvantages to sexual Propagation |
|
Definition
1. Difficult to prevent transmission of pathogens - so if the parent has a virus/ bacteria - it's likely that the cutting will be infected also
2 more costly than seed propogation |

-Definition : detached vegetative parts of the plant
-can regenerate an entire plant if given the right conditions
-there are four basic types of cutting |
|
|
Term
| Basic types of Roots 1)Stem cuttings |
|
Definition
-always include either terminal or lateral buds
-encourage the formation of roots by using
a)Intermittent mist
b)rooting hormones
c)bottom heat
d)rooting media |

| Basic types of cuttings 2) Leaf Cutting |
|
Definition
| a new plant is propagated from a single leaf (jade and African violet) |

Term
| Basic Types of Cuttings 3)Leaf -bud cuttings |
|
Definition
- used with species that make roots but not shoots from a leaf cutting.
- the shoots arise from the bud
-also called a heel cutting |
