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