| The pistil and the stamen of the flowers are the specialized organs responsible for the reproductive processes. |
|
| The stamen primordia differentiate from globular primordia into elliptic appendages of differing size. |
|
| We also have the species Astrantia major with green flowers filled with pinkish stamen which quiver in the slightest of breezes. |
|
| Prior to the aestivation of the calyx, pairs of stamen primordia are initiated. |
|
| The male blossom sits on a slender stalk, and the center stamen within the bloom contains the pollen. |
|
| The transfer of the pollen grain from the stamen to the stigma initiates the processes that can result in fertilization. |
|
| At the centre of each flower are grey-blue stamen and the plant forms a compact mass of foliage and flowers. |
|
| In some species the ten stamens are all united by their filaments or one stamen is free and the other nine are united. |
|
| Penstemons are sometimes commonly called beardtongues because the sterile stamen has a tuft of small hairs. |
|
| Its flowers are mostly yellow with maroon veins and stamen of the same colour. |
|
| Imagine a drawing of a flower, with eight petals around a stamen, on a touch-sensitive screen. |
|
| The families with one stamen and a varied number of petal-like staminodes show a great range of floral form. |
|
| The insect sticks to the stamen that sticks out from the side as it goes into the flower and pulls the anthers against its fur. |
|
| What probably happened is that a light frost killed the pollen in the male stamen at a temperature just below freezing, but leaving the female receptive. |
|
| In this population, the male cyathia produced on average 100 pollen grains more per stamen than the hermaphrodites, but this difference was not significant. |
|
| Usually the lateral stamens emerge first, then the anterior stamen. |
|
| One anterior petal is missing as well as a posterior stamen. |
|
| Single white flower with purple claws at the base of the petals and a lot of golden stamen. |
|
| Commonly the odd stamen is more or less reduced to a staminode or even lacking. |
|
| These traits included petal length, petal width, tallest stamen height, and gynoecium length. |
|
|
|
| In a martini stem glass, place a pink day lily, after removing the stamen, then garnish with a ball of sorbet of a color that harmonizes well with the colors of the flower. |
|
| One of the characteristic differences between the orchid family and other advanced monocots is that the fertile stamen or stamens are on one side of the flower opposite the lip. |
|
| Fit the stamen over the bolt and hold it in place until it adheres. |
|
| This is rejected by Chatin, who states that no trace of a fifth stamen exists in the Labiates, unlike the Scrophulariaceae. |
|
| Staminodia develop from normal stamen primordia, but with altered developmental processes and patterns. |
|
| Review the following terms and their significance for plant reproduction: flower, stamen, perianth, carpel, microsporangium, megasporangium, female gametophyte, male gametophyte. |
|
| Semi-double pink flower, with petaline among the stamen. |
|
| With a Leica stereomicroscope, the typical shapes of insect mandibles, hairs and antennae can be distinguished with the same ease as the calyx lobes, petals and stamen of flowers. |
|
| As well, the stamen threads are crumpled during flowering. |
|
| Flowers are small, dark red, petals with narrow white margins. 12 stamen. |
|
| The genus belongs to the Mallow family, whose flowers are typically characterized by stamen stalks growing together and surrounding the pistil like a tube. |
|
| Next the flowers were dissected and the pedicel and receptacle, one sepal, one petal, one stamen and the pistil were isolated. |
|
| These mutations, ts4 and Ts6, prohibit the development of the stamen while simultaneously promoting pistil development. |
|
| The point of this construction is to guide the proboscis of pollinating insects into the nectar in such a way that it unavoidably touches both the stigma and the stamen. |
|
| For Watson and Dallwitz, a staminode is a sterile stamen, or a modified structure identifiable as such, borne in the androecial region of the flower. |
|
| I peered closely at the blossom and thought how perfect the pink and white flowers were with each stamen dotted with yellow pollen like a miniature drum stick. |
|
| I have not included these in the study, because they are much more frequent and widespread than those cases with a single stamen or carpel, and are thus too trivial. |
