Plant structure
Term | Definition |
---|---|
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 and reproduce |
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 first whorl surrounding the reproductive structures |
sepals | Petallike 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 up the anther |
pollen | 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, ovule) |
stigma | Sticky substance on top of the Style, it traps and holds pollen |
style | Tubelike 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 |
