Science Reproduction
Plants and Animals Reproduction Terms
Term | Definition |
---|---|
Asexual reproduction | Offspring is created from a single organism (parent) and are exact copies of that parent |
Binary Fission | Divide into two identical cells |
Budding | Offspring grows out of the parent’s body. Not an equal dividing like binary fission |
Fragmentation/Regeneration | Offspring from out of broken off pieces of the parent |
Sexual reproduction | The genetic information from two parents is combined to create offspring with unique genetic traits |
Internal Fertilization | Fertilization (egg + sperm) occurs within the female usually |
External Fertilization | Fertilization occurs outside the female in a watery medium |
Angiosperms | Flowering Plant |
Petals | Attract Pollinators, protect the inner structure |
Sepal | To protect and support the flower, keep from drying out |
Stem | Provide support, transport, water, and nutrients, store water and food |
Anther | Produces Pollen (Sperm) |
Figment | Stalk that holds anther up |
Stamen | Male Parts |
Sigma | Sticky part where pollen sticks |
Style | Stalk that supports the stigma |
Ovary | Where fertilization occurs (pollen + egg = seed), seeds are turned into fruit |
Pistil | Female Parts |
Pollination | Hummingbirds, Birds, Bats, Butterflies, and Bees. Pollinators are attracted by nectar. Pollen attaches to the pollinator and brushes the sticky stigma. |
