The two phyla Cnidaria and Ctentophora makeup the radiate animals. Most radiates have tentacles or oral extensible projections around the oral end that are armed with cells that may function in defense and capture prey. The cells found within the tentacles are structurally and functionally unique to each phylum‚ such as the cindocytes in Cnidarians and colloblasts in Ctenophores. Cnidarians capture prey with special stinging cells called cindocytes. These cells are found throughout the epidermis

Organ Systems Project (Digestive‚ Excretory‚ Circulatory‚ Reproductive‚ Nervous) There is an enormous variety of life on our planet Earth ranging from simple cell bacteria to complex multicellular animals. Animals are creatures in the kingdom Animilia‚ one of the kingdoms in Whitakers 5 kingdom system. Their bodies consist of 555tanimal eukaryotic cells. Meaning their cell or cells contain a nucleus‚ are surrounded by a cell membrane (phospholipid bilayer) and can self-reproduce in a free

Cytochrome-C Comparison Brief Description: The molecular clock refers to mutations in DNA nucleotide sequence of genes occurring at a constant rate over time. The greater the difference in nucleotide sequence between two individuals of different species‚ the greater the amount of time has passed since they diverged from a common ancestor. The molecular clock helps to provide evidence to support conclusions previously based on comparative morphology and fossil records. Hypothesis: One hypothesis

Phylum Annelida L. annelleus = little ring Annelida have bodies consisting of many essentially similar ringlike segments (somites or metameres).This segmentation usually shows in both external and internal features‚ including muscles‚ nerves‚ and circulatory‚ excretory and reproductive organs. Phylum Annelida This phylum is divided into three classes: Oligochaeta: Earthworms - Most earthworms and their equals are inhabitants of damp soil and fresh waters. Hirudinea: Leeches - The leeches
