Heredity Unit 1
Term | Definition |
---|---|
Asexual Reproduction | Asexual reproduction is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only |
Binary Fission | is the division of a single entity into two or more parts and the regeneration of those parts to separate entities resembling the original |
Budding | Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site |
Fragmentation/Regeneration | Fragmentation in multi cellular organisms is a form of asexual reproduction in which an organism is split into fragments |
Sexual Reproduction | Sexual reproduction is a type of life cycle where generations alternate between cells with a single set of chromosomes and cells with a double set of chromosomes |
Internal Fertilization | Internal fertilization is the union of an egg cell with a sperm during sexual reproduction inside the body of a parent. For this to happen there needs to be a method for the male to introduce the sperm into the female's reproductive tract |
External Fertilization | External fertilization is a mode of reproduction in which a male organism's sperm fertilizes a female organism's egg outside of the female's body |
Angiosperms | A plant that has flowers and produces seeds enclosed within a carpel |
Petals | Petals are modified leaves that surround the reproductive parts of flowers |
Sepal | Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom |
Stem | The main body or stalk of a plant or shrub |
Anther | The part of a stamen that contains the pollen |
Filament | A slender threadlike object or fiber, especially one found in animal or plant structures |
Stamen | The male fertilizing organ of a flower, typically consisting of a pollen-containing anther and a filament |
Stigma | The stigma is the sticky stem of the pistil of the female reproductive system in a plant |
Style | It is a long, slender stalk that connects the stigma and the ovary |
Ovary | Enlarged basal portion of the pistil, the female organ of a flower |
Pistil | The female organs of a flower, comprising the stigma, style, and ovary |
Pollination | The transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization |
