Introduction: In this essay I will talk about two kinds of organisms that are called worms. That’s organisms use it in a labs. Which are the flatworm and the roundworms. However‚ every kind belongs to different phylum‚ so they are not closely related to each other. Flatworms ( phylum Platyhelminthes) and roundworms ( phylum Nematoda)‚ but there are many similarities and differences between these two types of organisms. Similarity: • There are many similarities between the two groups of worms‚ Platyhelminthes

Most animal phyla originated in a relatively brief span of geological time‚ however the diversity among them is extraordinary. Every organism is very unique a detailed in certain ways‚ comparisons of certain types of organisms can be very difficult. The class in which will be compared is that of the invertebrates. The main difference between coelomate and acoelomate body plans are that coelomates have a true coelom‚ which is a fluid-filled body cavity completely lined by tissue which is derived

Excretory System Of Cockroach The excretory organ of cockroach is the malpighian tubules. It is found at the junction of the midgut and hind gut and are about 150 in number. They are fine‚ yellow coloured and branched threads present in bundles. They lie freely in the haemolymph. The distal parts of the tubules extract inorganic ions‚ uric acid and amino acids by active transport and water by diffusion from the surrounding haemolymph. The filtrate moves towards the ileum. In the proximal parts

Ng Boon Yee/ Group B06/ A0099215Y Comparison of Organisms from the Class Oligochaeta and Class Chilopoda Animal phylogeny is an interesting and rapidly changing field of study. To date‚ there are about 1.5 to 1.8 million species of animals that have been named and described by biologist with 15‚000 to 20‚000 new species named each year. However‚ millions more species are yet to be discovered and classified. Taxonomists have divided the animal kingdom into about 35 phyla (Solomon et al.‚ 2011). Out
