A large number of these animals reproduce through asexual budding. That’s a reproduction process where fragments break off the body and develop into new life. Other species actually stretch their base and split across the middle. The act results in two new creatures. In yet other families, sm...
What chordates can reproduce by budding? The subphylum Urochordata or tunicates can reproduce sexually or asexually. Usually, a tunicate will prefer to reproduce sexually (with a separate male or female) if there is one available. However, if there is not, it can reproduce asexually (by pro...
The sexually mature medusa stage reproduces by the spawning and fertilization of eggs with sperm, while the sexually immature polyps reproduce by budding. It is the unique life cycle with transformation back into the polyp state that can result in so many genetically identical offspring and no ...
We recently uncovered and characterized the size-dependent behaviors and adult tissue structures underlying asexual reproduction in the planarian,Schmidtea mediterranea1(Fig.1a). These highly regenerative flatworms exist in both sexual and asexual biotypes. The latter reproduces solely through transverse fi...
The main limitation of monolayers of epithelial cells is the loss of the complex 3D organization of intestinal organoids such as buddings that reproduces in vitro crypt domains. 3.3 Barrier function A crucial function of the intestinal epithelium is to form a physical and immunological ...
metazoans, diploblastic, radially symmetrical, contain specialized cells called cnidocytes that contain nematocyts, reproduce through budding or release of gametes, can have a polyp or medusa body plan, primitive nervous system (nerve net), gastrovascular cavity, carnivorous Anthozoa have polyp body ...
What are the two structures that allow angiosperms to be the dominant form of plant life in most terrestrial ecosystems? What are organisms with similar characteristics that can interbreed and produce fertile offspring called? Some organisms (e.g. certain fungi) reproduce asexually when the envi...
Since there are 2 kinds of gametes, and plants reproduce, do plants have gender or do they asexually reproduce? Explain. Sexual reproduction requires that half of the chromosomes in a zygote come from one parent and the other half from the second parent. a. Describe the process by...
This is implemented by creating a new group with half of all group members that are selected randomly. Dispersal that occurs through group splitting is often called budding or propagule dispersal [13, 30] and is frequently found in social mammals and social insects [19–27]. Model analysis ...
