Fruits and seeds
| Question | Answer |
|---|---|
| Pistil | The female reproductive part of a flower |
| Stigma | The tip of the female reproductive structure of a flower where the pollen lands |
| style | Connects the stigma to the ovary of a flower |
| ovary | A flower structure that encloses and protects ovules and seeds as they develop. |
| ovule | A structure that contains an egg cell |
| sepals | Leaflike parts that cover and protect the flower bud |
| petals | modified leaves which are usually bright in color to attract pollinators. |
| pollination | The transfer of pollen from male reproductive structures to female reproductive structures in plants |
| cross pollination | a reproductive process in which pollen from one plant is transferred to the stigma of another plant |
| fruit | A mature ovary of a flower that protects dormant seeds and often aids in their dispersal. |
| inferior ovary | ovary under petals |
| superior ovary | ovary over petals |
| Dry fruits | fruits whose seeds dispersed by wind, water, gravity, or animals to which the become attached/ Ex: grains and legumes |
| Fleshy fruits | fruits that evolved to attracted animals that will eat thme, but then spit out, drop, or pass the seeds unharmed away from the mother plant. |
| pericarp | ovary wall |
| endocarp | the inner most part of the fruit wall, covering the seed |
| mesocarp | the middle layer of the pericarp, often the part that is eaten. |
| exocarp | outermost layer of the pericarp of fruits as the skin of a peach or grape |
| drupe | Fleshy, simple fruit with a hard and stony endocarp, ovary superior, and single seeded (pitted). ex: cherry, olive, coconut |
| berry | Fleshy, simple fruit with fleshy/slimy endocarp with many seeds ex: tomatoe, grape, green pepper |
| Pome | Fleshy, Simple fruit made mostly of receptacle tissue. ex: apple, pear, quince. |
| Nut | Dry fruit that do not split open at maturity with a hard/thick pericarp and a cup at it's base. ex: acorn, chestnut, hickory. |
| Samara | Dry fruit that do not split open at maturity whose ovaries occur seperately. ex: maple, ash, elm.Dry at maturity; winged; single-seeded |
| Achene | Dry fruit that do not split open at maturity with a thin/not winged pericarp. Single seed attached to pericarp only at it's base. ex: sunflower, buttercup. |
| function of flower | reproduction and attracts pollinaters and Turns into Fruit, Plants |
| pedicel | Supports flower, connects it to stem |
| Sepals | Leaf like parts that cover and protect the flower bud |
| stamens | MALE REPRODUCTIVE ORGANS OF A FLOWER |
| pollen | A fine dust that contains the sperm of seed-producing plants |
| filament | Supports the anther |
| Incomplete flowers lack | one or more floral |
| organs, for example | |
| stamens or carpels | |
| Complete flowers have | sepals, petals, stamens, carpels |
| fruits | the sweet and fleshy product of a tree or other plant that contains seed and can be eaten as food. |
