Thus pollination takes place, after which the … In many aquatic plants with emergent flowers, pollination occurs by wind or insects, e.g., Lotus, Water Lily, Water Hyacinth. Pollen transfer is effected by wind, water, and animals, primarily insects and birds. BirdsD. That is, the zygote began … The pollen grains released by the male flower reaches to female flower for fertilisation through water currents. Female flowers … I’ve posted this to give you a similar “face-on” view as you do with the image of the yellow Lotus japonicus , which I think makes it a little bit easier to compare how the morphology reflects the pollination-mode. Question 55. WindC. Cleavage of cytoplasm in between the two daughter nuclei to form two daughter cells. Tannupandit008 Tannupandit008 Answer: In this plant, pollination is done by pollinating agent i.e., water. Lotus maculatus, a related species to Lotus berthelotii that is also bird-pollinated (and also common in cultivation). Their range includes the southern parts of Texas, California, New Mexico and Arizona. After self‐pollination, there was an inversion of the process in C. multiflorus (in a single ovule). Pollination The transfer of pollen grains from the anther of a stamen to the stigma of a pistil is called pollination. By water current they are carried to the proximity o r the female flowers where the anthers burst to set the pollen grains free. (b) Regeneration. One important bat is the Mexican long-nose bat, which dwells in large colonies. Before pollination the male flowers get detached from the mother plant and float on the water. Upon reaching the stigma of the female flower, the pollen tube germinates, just like in other flowering plants. This type of pollination mainly observed in Graminae. Angiosperm - Angiosperm - Pollination: Effective pollination involves the transfer of pollen from the anthers to a stigma of the same species and subsequent germination and growth of the pollen tube to the micropyle of the ovule. Add your answer and earn points. Epihydrophily takes place over the surface of water, e.g., Vallisneria. Hypohydrophily occurs below the surface of water, e.g., Zostera, Ceratophyllum. All aquatic plants are not hydrophilous some are anemophilouse.g.Potamogeton, Myriophyllum or Entomophilouse.g.Alisma, Lotus. Hydrophily is … ) In Vallisneria pollination takes place by the agency of:A. WaterB. Only pollen grains compatibel i.e. Bats take the night shift, playing a major role in pollinating crops and spreading seeds. Ans: In Vallisneria pollination is through hdrophilly ie through water. Most people associate pollination with bees and birds but often forget the work of their furry colleagues: bats. In Valilisneria, the female flower appear on the surface of the water as it have a long stalk. (CCE 2012) Answer: (a) Elongation of nucleus followed by division into two. In Vallisneria pollination takes place by the agency of 1 See answer shailendras97 is waiting for your help. (b) Hydrophily :When the pollination takes place through the agency of water, it is known as hydrophily. (b) In which two of the following organisms, regeneration takes place : Lion, Planaria, Hydra, Lotus. Insects Get the answers you need, now! The first zygotic division takes place at about 5 DAP, when the endosperm presents 4–16 nuclei in C. multiflorus and 8–16 nuclei in C. striatus. Pollination takes place in two different ways: (i) Self-pollination: When the pollen grain from the anther of one flower reaches to the stigma of the same ‘ flower, it is called self-pollination. Planaria, Hydra. Pollination involves the transfer of male gametes from the anthers to the female gametes in the ovary. Hydrophylly is of two types— hypohydrophily and epihydrophily. Ovule ) ( CCE 2012 ) Answer: in Vallisneria pollination takes place over the surface water! For fertilisation through water currents in Vallisneria pollination takes place by the agency of 1 See shailendras97.
