Hydra


Hydra Microscope Slide




Describe your organism using words.  

Long rectangular shape. Pink, smooth, skinnier where the bud touches. Has tentacles on top end and on tip of bud. Appears to have a thinner, lighter pink ring around outer bound, reminding me of a membrane. _______________________________________________________________________________

What kingdom and phylum does your organism belong to? Kingdom- Animalia; Phylum- Cnidaria  What characterizes this group? Kingdom-Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their life

Characteristics of Phylum Cnidaria:- 
1)Radially Symmetrical. 
2)Body multicellular, few tissues, some organelles. 
3)Body contains an internal cavity and a mouth. 
4)Two different forms exist, medusa and polyp 
5)Reproduction is asexual or sexual. 
6)Has a simple net like nervous system. 
7)Has a distinct larval stage which is planktonic. 
8)Lives in aquatic environments, mostly marine. 
9)Mostly carnivorous otherwise filter feeders. 
10)May have a minimal skeleton of chiton or calcium carbonate.

How does this organism reproduce?  (Include sexual or asexual, formal name of reproduction, process, results in haploid or diploid?) When food and other resources are readily available, Hydra reproduce asexually. Hydra can also reproduce sexually, but most often reproduce asexually through budding. Tentacles will form on the hydra's body, and eventually form a bud, which will leave the mother cell when able to live on its own. Then continuing the process of tentacle budding. 

Of the other 4 organisms you observed, how is yours similar in reproduction compared to the others?

Just like the Hydra, all of the organisms were able to reproduce both sexually and asexually; however, none others reproduced because of tentacles.

How is it different from the others? Creates tentacles and to bud.
