Continuous self-pollination results in inbreeding depression. Explain any two devices by which autogamy is prevented in flowering plants. In order to avoid self-pollination,cross-pollination is encouraged in plants as follows : a. This also results in homozygous genes. Outbreeding Devices. 1. List three devices, which flowering plant have developed to discourage self pollination? asked Dec 7, 2018 in Biology by kajalk (77.6k points) cbse; class-12; 0 votes. Class-12CBSE Board - Outbreeding Devices and Pollen-Pistil Interaction - LearnNext offers animated video lessons with neatly explained examples, Study Material, FREE … Because the majority of flowering plants produce hermaphrodite flowers and are likely to come in contact with the stigma of the same flower. continued self pollination leads to inbreeding depression list three devices which flowering plants have developed to discourage self pollination - - TopperLearning.com | bhl4jvqll Plant species were classified pertaining to the nourishment of organisms into three categories: (i) autotroph, plant that makes its own food, (ii) hemiparasite and parasite, partial or total parasite that obtains its nourishment from a living plant and (iii) insectivore, plant that obtains partially its … Outbreeding devices : Majority of flowering plants produces hermaphrodite flowers which undergo self-pollination. Flowering plant have developed many devices to discourage self-pollination to encourage cross-pollination. Thus plants are adapted to promote cross-pollination. Make a list of any three outbreeding devices that flowering plants have developed and explain how they help to encourage cross-pollination. explain any three inbreeding devices in flowering plant. Concept: Pre-fertilisation - Structures and Events - Pollination. Flowering plants have developed many devices to discourage self-pollination and to encourage cross-pollination. This is done by enclosing the emasculated flowers in muslin, oil, paper or polythene bag. Describe any two devices in a flowering plant which prevent both autogamy and geitonogamy. The first two plants show the dioecious condition in which male and female flowers are borne on separate plants while the fourth plant exhibits monoecy, where male and female flowers are borne on the same plant. In some species, pollen release and stigma recepitivity are not synchronized. Three inbreeding techniques in flowering plant are :- Emasculation- It is technique that involves removal of anthers from the flower buds before it splits apart in bisexual flowers. Self-pollination is common and more likely to happen in the case of hermaphrodite flowers but a successive series of self-pollination affects negatively and causes inbreeding depression. Pink flower = female flower; Blue flower = male flower; Bicolored flower = bisexual/hermaphrodite flower. The continued self-pollination leads to chances of inbreeding depression. This is known as outbreeding. Continued self pollination lead to inbreeding depression. This process is known as budding. Artificial pollination- When stigma from emasculated flower becomes mature it is … In some other species, the anther and stigma are placed at different position. 1 answer. Fig.4.1.Terminology.
