For science class
Question | Answer |
---|---|
Survival | The struggle to remain living by adapting (changing) to one's surroundings |
Reproduction | The production of new plants asexual or sexual |
Defense | A set of plant traits (characteristics) that help them to survive |
Perfect Flower | Flowers that have both male AND female parts |
Imperfect Flower | Flowers with either male OR female parts |
Pollination | When pollen moves from male parts to female parts by a pollinator such as bees, birds, wind, humans, or other organisms. Fertilization then occurs where a seed and embryo develop. |
Petals | The colorful parts of a flower, the whorl surrounding the reproductive structures |
Sepals | Petal-like structures, often green, at the base of a flower, Protect the bud while developing |
Stamen | The male reproductive structures (includes anther, filament, and pollen) |
Anther | The structure located at the top of the filament, carries the pollen |
Filament | A threadlike structure that holds the anther |
Pollen | The male sex cell that donates half of its DNA ( traits) to make a seed. Usually a yellowish powdery substance that is carried by a pollinator. |
Pistil | The female reproductive structures (includes stigma, style, ovary, and ovule) |
Stigma | Sticky substance on top of the Style, it traps and holds pollen. |
Style | Tube-like structure that holds up the Stigma |
Ovary | At the bottom of a flower that holds the ovules. The ovary turns into the fleshy fruit we eat |
Ovule | Female sex cells that donate half of its DNA (traits). Ovules develop into seeds when fertilized by pollen. |
