Asexual and Sexual reproduction Flashcards
Petals
Colorful leaves that surround the reproductive parts of a flower.
Sepals
Outermost leaves surrounding the reproductive flowers.
Stamen
Male reproductive parts of a flower
Anther
Top part of stamen; produces pollen
Filament
Stem part of the stamen holds up-right/ supports anther.
Pollen
Male flower sperm
Pistil
Female reproductive organ of a flower. Contains stigma, style, and ovary.
Stigma
Female flower structure; top sticky part of pistil to collect pollen.
Style
Female flower structure; the stalk of the pistil that connects stigma to ovary.
Ovary
Female flower structure; lower part of pistil; Contains ovules.
Ovules
Located in the ovary of flower; when fertilized by pollen develop into seeds.
Pollinator
Anything that is capable of transporting pollen from the anther to the stigma. Includes insects, birds, animals, wind, weather, and people.
Sexual reproduction
The process of producing offspring that results from the union of female and male sex cells (egg and sperm).
Asexual reproduction
The process of producing identical offspring from one parent.
Binary Fission
A type of asexual reproduction where one single organism divides equally to produce two new, identical organisms. EX. (Ameobas paramecium, hydra)
Budding
Type of asexual reproduction where a bud-like formation grows on a parent organism matures and falls off to produce a new organism. (EX yeast, hydra.)
Sporulation
When spores (asexual reproductive cells) develop into a new organism when conditions are favorable.
Regeneration
Regrowing body parts from limbs lost to predators.
Fragmentation
The process of producing new organisms from fragments of another organism.
Parthenogenesis
The process of producing female offspring asexually from one parent offspring.
Vegetative Propagation
A type of asexual plant reproduction that occurs in where a part of a plant (root, stem, or leaf) grows into a new identical plant. Examples include tuber grafts rhizomes runners bulbs and sporulation.
Natural vegetative propagation
Vegetative propagation that occurs without human interference. For example, includes tubers, runners, rhizomes, and bulbs.
