Plant Sexual Reproduction Flashcards
1
Q
What is pollination?
A
The transfer of pollen grains from the anther to the mature stigma of a plant of the same species
2
Q
What is self pollination?
A
The pollen from the anthers of a flower is transferred to the mature stigma of the same flower or another flower on the same plant.
3
Q
What is cross pollination?
A
Pollen is transferred from the anthers of one flower to the mature stigma of another flower in another plant of the same species
4
Q
Genetic implications of self pollination
A
- less genetic variation
- greater chance of harmful alleles brought together
- preserve successful genomes
5
Q
Genetic implications of cross pollination
A
- more genetic variation
- reduces chance of producing harmful allele combinations
- species can survive changing environment
6
Q
Ensuring cross pollination
A
- dichogamy
- anther below stigma
- genetic incompatibility
- separate male and female flowers on same plant
- separate male and female plants
7

8
Q
What is the plumule?
