| 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; it does not involve the fusion of gametes, and almost never changes the number of chromosomes. |
| Binary fission | Fission, in biology, 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 | (of a plant) having or developing buds |
| fragmentation regeneration | the process of breaking up of parent animal into small parts, each of which can grow into a new complete individual. This process of asexual reproduction is found in planaria and hydra. |
| 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 | When an egg is fertilized inside the female |
| External fertilization | When an egg is fertilized outside the body. |
| Angiosperms | a plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees. |
| Petals | Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. Together, all of the petals of a flower are called a corolla. |
| Sepal | each of the parts of the calyx of a flower, enclosing the petals and typically green and leaf like. |
| Stem | A stem can be the central root of a word, the supporting structure of a plant, or the thin, cylindrical part of a glass goblet. |
| 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 part of the pistil where pollen germinates. |
| Style | The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. |
| Ovary | In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynecologic. |
| Pistil | The pistil, centrally located, typically consists of a swollen base, the ovary, which contains the potential seeds, or ovules. |
| Pollination | Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. |
