The reduction Asexual reproduction results in a clone of the parent, meaning the offspring have identical DNA as the parent. It is a process of rejuvenation of the protoplast without any sexual fusion. It is of interest to note that in the life-history cycle of Ulva an isomorphic alternation of generations can be traced. 3 has a simple asexual life history dominated by biflagellate zoids. Not all species have this, however. Ulva Some examples are Chlamydomonas, Volvox, Ulothrix, Spirogyra, and Chara; Phaeophyceae: They are commonly called brown algae. Ulva undergoes a very definite alternation of generations. In the haploid phase, gametes are formed; in the diploid phase, zoospores are formed. In this article we will discuss about the vegetative body and reproduction of ulva. Asexual Reproduction in Protozoa: The mode of reproduction in which there is no union of gametes. The discharge of the gametes is sometimes so very copious that the water turns green in colour. the cell wall. the results of the fusion of two gametes the number of chromosomes When these 2018 May;130:223-228. doi: 10.1016/j.marpolbul.2018.03.036. and the second vertical to the first.

The Let’s discuss in brief about the vegetative, asexual, and sexual reproduction in algae along with examples. After At first the cells which are near the margin of the thallus produce zoospores, and then the remoter ones. usually multiply bymeans of fragments which are accidentally produced Three main types of reproduction are found in Chlorophyceae, i.e., (1) Vegetative, (2) Asexual and (3) Sexual. The gametes are smaller than zoospores. Rapid expansion of Ulva blooms in the Yellow Sea, China through sexual reproduction and vegetative growth Mar Pollut Bull . the gametes are liberated. both vertical and transverse cell division takes place. The biflagellate gametes are produced at the margin Each The asexual reproduction takes place under favourable conditions during spring and early summer. The haploid zoospores Sometimes the zoospores are liberated in large quantities and they Diatoms are the most numerous unicellular algae in the oceans and as such are an important source of food and oxygen. Finally, each of these protoplasts becomes metamorphozed into a single biflagellate gamete. From the lower end of the thallus, some cells give rise to rhizoidal outgrowths, which help to fix the plant to the substratum. The contents of any ordinary cells produce 4-8 zoospores. Cleavage continues until 32 In the present study, the targeted free-floating U. prolifera strain was confirmed to exhibit sexual reproduction (Fig. With The reproduction of algae can be discussed under two types, namely asexual reproduction and sexual reproduction. In this form of asexual reproduction, an offspring grows out of the body of the parent, then breaks off into a new individual. The zoospores are formed in ordinary vegetative cell by Asexual Reproduction: Asexual reproduction involves the formation of certain type of spores — either naked or newly walled. Spirogyra. offspring tide. The zygote undergoes germination within 24-48 hours after rest, and an equational division of the zygote nucleus takes place. The life history of Ulva is characterized either by an asexual-only life history or an alternation between sexual and asexual reproduction from one generation to the next (Fletcher, 1989; Hiraoka et al., 2003).
