14. Reproduction In Plants Flashcards
asexual reproduction
a process resulting in the production of genetically identical offspring from one parent
Sexual reproduction
A process involving the fusion of he nuclei of two gamete’s to form a zygote and the production of offspring that are genetically different from each other
Gamete
A sex cell with half the normal no of chromosomes
Fertilisation
The fusion of the nuclei of two gametes
Zygote
A cell that is formed by the fusion of two gametes
Diploid
Having two complete sets of chromosomes
Haploid
Having only a single set of chromosomes
Mitosis
Division of a cell nucleus resulting in two genetically identical nuclei
Meiosis
Division of diploid nucleus’s -resulting in four genetically different haploid nuclei
Sepals
Leaf like structures that form a ring outsource the petals of a flower
Petals
Coloured structures that attract insects or birds to a flower
Stamen
The male parts of a flower
Filament
The stalk part of a stamen
Anther
The structure at the top of a stamen inside which pollen grains r made
Pollen grains
Small structures which contain the male gametes of a flower
Carpel
The female part of a flower
Ovary
The part of the flower that holds the ovules
Ovules
Small structures that contain the female gametes
Style
The part of a carpel, that connects the stigma to the ovary
Stigma
The part of the flower that receive pollen
Pollination
The transfer of pollen. Grains from the male part of the plant to the female part of the plant
Self pollination
The transfer of pollen grains from the anther for a flower or the stigma of the same flower or a different flower on the same plant
Cross pollination
The transfer of pollen grains from the anther of a flower to the stigma of a flower on a different plant of the same species
Seed
The structure that develops from an ovule after fertilisation
