100021805 | Angiosperms | A plant that produces seeds that are enclosed in a fruit. | 0 | |
100021806 | Ovary | Seeds develop in the ovary. The ovary is located in the flower. | 1 | |
100021807 | Fruit | the reproductive structure of an angiosperm. | 2 | |
100021808 | Flowers come in all | sort of sizes, shapes, and colors. | 3 | |
100021809 | All flowers have the same purpose | reproductions | 4 | |
100021810 | Petals | Colorful structures that produce an odor to attract insects or other animals. These organisms ensure that pollination occurs. | 5 | |
100021811 | Sepals | Sepals protect the developing flower. Sepals surround the flower when it is still a bud (undeveloped flower). | 6 | |
100021812 | Stamen | The male reproductive part. Consists of two parts: Filament - A thin stalk that holds up the anther. Anther - Pollen is produced in the anther. Pollen - Inside a pollen grain is a sperm cell. | 7 | |
100021813 | Pistil | Female part of the flower usually found in the middle. Consists of three parts: Stigma - The top of the pistil that is sticky so it can catch pollen. Style - tube that connects the stigma to the ovary. Ovary - A hollow structure which contains ovules that have eggs. | 8 | |
100021814 | Reproduction Stages | 1.Pollen grains fall on a stigma. 2.The Pollen grain produces a pollen tube that grows into the ovule. 3. A sperm cell travels down the style inside the pollen tube. It joins the egg cell and fertilization occurs. 4. The fertilized egg becomes a zygote which will develop into the seed's embryo. | 9 | |
100021815 | Pollination | The transfer of pollen from male reproduction structures to female reproduction structures in plants. | 10 | |
100021816 | Fertilization | The joining of a sperm cell and an egg cell. | 11 | |
100021817 | Pollinators | Birds, Bats, Insects (Bees), Wind. Nectar: a sugar-rich food is located deep inside the flower. When an animal/insect enters a flower to eat the nectar, it brushes up against the anther and becomes coated with pollen. | 12 | |
100021818 | Self Pollinating | Some of the pollen can drop onto the flower's stigma as the animal leaves the plant. | 13 | |
100021819 | Cross Pollinating | The pollen can also be brushed onto the next flower the animal visits. | 14 | |
100021820 | Fruit Ovary | As the seeds develops, the ovary changes into a fruit. Fruit: A ripened ovary and other structures that enclose one or more seeds. Animals that eat fruits help to disperse the seeds. | 15 | |
100021821 | Monocots | Monocots: Grasses (corn, wheat, and rice) Plants (lilies and tulips) | 16 | |
100021822 | Dicots | Dicots: Plants (roses, violets, dandelions) Oak and Maple trees | 17 | |
100021823 | Medicines | Some angiosperms are used to make medicines. - Aspirin was first made from a substance found in the leaves of willow trees. - Cortisone is a medicine made from the roots of the Mexican Yam. (treats arthritis/ joint problems). | 18 | |
100021824 | Angiosperms and the living world | Angiosperms are an important source of: Food - Animals eat flowering plants such as grasses and leaves of trees. - People eat vegetables, fruits, a n d cereals (all are angiosperms). | 19 | |
100021825 | Clothing/furniture | People produce clothing and other products from angiosperms. - Seeds of cotton plants are covered with cotton fibers. - Stems of flax plants provide linen fibers. - Sap of tropical rubber trees are used to make rubber for tires. - Furniture is made from wood of maple, cherry, and oak trees. | 20 |
