HomeThe reproductive part of the plants. In angiosperms, this is the main parts used to reproduce. Also known as a *bloom* or *blossom*, is the reproductive structure found in flowering plants (plants of the division Magnollophyta, also called angiosperms). [underground orchid] [raflesia] has distinct odour, this is to attract pollinators > the main goal of every organism is to reproduce > How do you define species? > Group of organisms sharing the same characteristics and are capable of reproduction. If you are not capable of interbreeding with another species, you are not the same species. There are exceptions to the rule. Flowers come in different structures, different colors. [kalabasa flowers] male and female [gumamela] is both a complete and perfect flower 1. Complete Flower - has both the reproductive and the vegetative parts. Reproductive Part Stamen > Anther, Filament Pistil > Stigma, Style, Ovary Vegetative Part Sepal, Petal > Perianth 2. Incomplete Flower - has missing parts from either reproductive or vegetative 3. Perfect Flower - Pistil + Stamen 4. Imperfect Flower - Pistillate (only has pistil), Stamenate (only has stamen) Parts of the Flower - Peduncle - Pedicels - Receptacle - Sepals (Calyx: group of sepals) - also assists in photosynthesis - Petal (Corolla: group of petals) - it is usually colorful and its main function is to attract pollinators - Perianth (Collective terms for all the sepals and petals) Inflorescence - Are divided into several florets or compound flowers Solitary - also known as simple flowers Reproductive Parts of the Flower Stamens 1. Anther - also known as the pollen sac and contains the pollen grains. When pollen grains germinate. 2. Filament - supports the anther Pistil 1. Stigma - this is where the pollen grains land to germinate and produce the sperm cells 2. Style - tube that connects the stigma to the ovary. 3. Ovule - Immature seed. can be found in the inside of the ovary. 4. Ovary - the mature ovary will develop to become fruit. - Superior - ovary is attached above the petals and sepals - Inferior - ovary is attached below the petals may be inferior or superior relative to the attachment of the sepals and/or petals in relation to the ovary. Androecium - collective term for all the stamens in a flower. one or two whorls of stamens, each a filament topped Gynoecium - collective term for all the pistils in a flower. the female reproductive organ in the flower is the carpel. This contains an ovary with ovules (which contain female gametes) {it is synonymous to female reproductive organ for purposes of examination} Apocarpous - A pistil may consist of a number of carpels merged together, in which case there is only one pistil to each flower, or of a single Plants based on when they flower **Annuals** - completes the cycle in a single season and ends with the death of the parent plant {ex. humay} **Biennials** - take two growing seasons to complete the cycle **Perennials** - may take several to many growing seasons to go from a germinated seed to a plant producing new seeds {ex. fruit trees such as lanzones, mangoes, atis} Flowers based on how they're pollinated **Cleistogamous flowers** - are self pollinated, after which, they may or may not open. Many Viola and some Salvia species are known to have these types of flowers. **Entomophilous flowers** - attract and use insects, bats, birds or other animals to transfer pollen from one flower to the next. Flowers commonly have glands called ***nectaries.*** Flowers also attract pollinators by scent and color. **Anemophilous flowers** - (wind-loving flowers) use the wind to move pollen from one flower to the next, examples include the grasses, Birch trees, Ragweed and Maples.
