Phylum Essays

Crayfishes are part of the subphylum Crustacea, and are part of the Phylum Arthropoda. Phylum Arthropoda have a bilateral body symmetry which means the body is divided into similar external right and left halves. The tissue organization of Phylum Arthropoda have three tissue layers, ectoderm, endoderm, and mesoderm; thus it is triploblastic. The body cavity of the phylum is coelomate meaning its organs are lined with mesoderm. Phylum Arthropoda embryonic development is protostome which means that the

Writing assignment #3 Phylum Platyhelminthes, known as flatworms, which also include the Planarian. Animals within this phylum are the first organisms to evolve by having bilateral symmetry, meaning that their body is equally divided into left and right halves. Also by becoming triploblastic organisms, having three different tissue layers, the endoderm (inner layer), ectoderm (outer layer) and mesoderm (third layer) these structures will be the base for the adult body. They lack a body cavity and

A clam is a type of mollusk that is part of a group of sea creatures known as bivalves, which includes mussels, oysters, and scallops. Clams are considered to be a shellfish as they are enclosed within a shell and they are widely eaten as a popular seafood around the world. Facts about clam’s nutrients Clams are popular around the world as they are easily available and nutritional. Clams are considered to be one of the world’s most sustainable seafood resource as they are easy to manage and grow

Observations: During the dissection, there might have been a few things observed. Two main observations that may have been noted was the change of colour and ring like segments. It may have been noted that the back and front side of the earthworm consists of two different colours. The back side of the earthworm is referred to as the dorsal side and the front side of the earthworm is referred to as the ventral side. A distinct observation is the fact that the ventral surface of the earthworm is a

1. The Phylum Chordata consists of chordates that are defined by the four fundamental characteristics that they possess such as the pharyngeal gill slits, muscular post-anal tail, dorsal, hollow nerve tube and the notochord (Department of Biology 2008). However, the adult humans lack two of these significant characteristics, which are the post-anal tail and the notochord. Furthermore, humans are classified as chordates due to the similarities within characteristics. For example, humans posses the

Phylum Cnidarian a. Feeding Cnidarians have only one opening called the gastrovascular cavity. This is where the food enters and the waste leaves. Cnidarians are hunters. They paralyze their prey before putting it in their mouth. To cut, and stick to their prey, Cnidarians use their nematocysts. Their Nematocysts contains toxic chemicals to kill whatever they are hunting, their prey. b. Digestion Digestion begins in the gastrovascualr cavity. This cavity is a digestive chamber. Digestion in this

Sexual reproduction is most common type of reproduction among the plants and animals. They are of following types; 1) Syngamy: The fusion of gametes takes place completely, if male and female gametes are produced by same cell or organism and both gametes fuse together to form a zygote, this is called as Autogamy, paramecium is its example. Another is Anisogamy in which some organisms produce two types of gametes. Both types of gametes differ from each other in their shape and size and are known

physical attributes of the living being. The present framework incorporates eight noteworthy positions: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. Each known life form is arranged into these positions. In this paper, we will look at phylogeny of the Sea Squirt and the Sea Otter, and furthermore investigate the UCMP site. Part I: Sea Squirt List the Kingdom and Phylum, for the sea squirt

Echinodermata and Mollusca is the two common phylum in the kingdom Animalia. Echinodermata consist of five large classes which are, class Crinoidea, example feathers star, class Asteriodea, example star fish, class Ophiuroidea example, brittle star, class Echinoidea, example sea urchins and the class Holothroidea, example sea cucumber. Phylum Mollusca consist of six major classes, which are Monoplacophora, Gastropoda, Cephalopoda, Polyplacophora, Scaphopoda and the last class which is the Bivalvia

The five kingdoms of life are monea, protista, fungi, plantae , and animalia, which include animas like clams. Within the Animalia kingdom that are different groups, each which are called phylums, and clams are considered in the phylum group known as mollusks. Mollusks which derive from the latin word mollis, means "soft". In the world ther are 1500 different kinds of mollusks whome are grouped into six different classes. One of these classes are called bivalves, which are aquatic mollusks

Zygomycota Structure - They have Cell walls which are made of chitin-chitosan. Zygospore which are mature has thick walls. Description - In the kingdom of fungi they are very small group and they are the Phylum Zygomycota.They can reproduce asexually or sexually with the help of process cis a classification that encompasses many dialled conjugation.In the classification of Zygomycota you can see many dfferent species and they all have a genome structure which are different. Characteristics

Cephalopods contain chromatophores which are pigment sacs that change color to match their surroundings. They are the only phylum to possess an active image generating neuromuscular system (Hochner, 2004). They are perfect for camouflage against predators since they are soft-bodied and vulnerable to other mammals. There are 5 different sacs of chromatophores including black

The Yellow Tongued Duckweed Frog descended from the Green Frog. Both of these frog species are part of the Animalia Kingdom. They are heterotrophs, they depend on other organisms directly or indirectly for food. Phylum - Chordata. The Yellow Tongued Duckweed Frog belongs to the Phylum Chordata. All chordates have something in common, which is their main feature, the notochord. The notochord is a rod that supports the nerve cord. This is a bundle of nerve fibers which connect the brain with the

Australian Giant Cuttlefish are in the following taxons, being ordered largest to smallest, Animalia, Mollusca, Cephalopoda, Sepioloida,Sepiidae,Sepia, lastly Apama. Their scientific name is, Sepia apama coming from their genus and species. Sepia apama is found about 100 meters under water around the southern coasts of Australia and Tanzania, in the seagrass beds of these coastal waters. Sepia apama typically eat small like crabs organisms called, crustaceans, and small fish. Sepia apama has predators

The word chameleon has been defined as something or someone that changes their appearance to fit into a certain stereotype or mold. This word was originated from the actual animal, the chameleon, because they blend into their environment. Why do chameleons change their color? It is a common misconception that chameleons change their color to hide from predators. People have come to this understanding about chameleons from television shows, teachers and even literature. While it is partially true

Discuss convergence in animals, providing examples from both arthropods and vertebrates. (discussing convergence in the phylum arthropods with examples from within this phylum and likewise for the vertebrates.) Convergent evolution is the process in which organisms which are not closely related derive akin traits separately due to the need for adaptation to similar environments or ecological niches. There may be resemblances at a phylogenetic level, but the basic DNA sequences are different. Morphologically

The bullfrog and the crayfish are similar and different in many different ways. To start off the crayfish is in the phylum arthropoda, they are invertebrates, and they can be classified as a cheliped which is a shellfish with one large claw and one tiny claw. Bullfrogs are in the phylum chordata and they are vertebrates. Both animals can be found in streams and ponds but bullfrogs can also be found in marshes but crayfish cannot. Bullfrogs reproduce externally which is when the egg is fertilized
