Tissues are necessary to produce organs and organ systems Tissues, organs, and organ systems enabled the evolution of large, multicellular bodies. A skeleton supports the tissues of large animals. The cells are held together by protein structures called junctions that extend from one cell to another. An abundance of extracellular proteins also support the cells. During embryonic development , cells become specialized and tissues form. The growth of tissues, organs, and organ systems therefore requires a period of embryonic development. Heterotrophs consume their organic food. Except for sponges, they ingest food and digest it in a central cavity. Heterotrophy often requires motility to capture prey. Animals have motility during at least some part of their
Lecture 13 Simple sponges, cnidarians, and flat worms are examples of acoelomate animals. A few phyla, like the nemotodes, possess a coelom that is not considered http://www.biology.buffalo.edu/courses/bio129/medler_lectures/lecture13.html
Extractions: October 28, 2004 Powerpoint Set #9 Animal Diversity Next, we will make a brief survey of the major animal phyla. Of the 30 distinct phyla, most animals fall within one of 9 different groups. We will discuss these beginning with the simplest animals, the sponges, and finish with the phyla that we and the other vertebrates are members of, the Chordata. 1. Porifera The earliest known animals are thought to have evolved from colonies of single-celled protests. Living sponges, members of the phylum Porifera, are probably similar to these earliest animals. Sponges sessile animals formed by a rather loose association of cells and are filter feeders. Flagellated cells known as choanocytes, or collar cells, draw water into the middle of the animal through small hole, or pores. Water is then released from the animal through an excurrent siphon. Small particles, such as algae or bacteria, are drawn into the animal by the water currents and the spongeÌs cells engulf, or eat, the particles through a process of phagocytosis. Phagocytosis ("cell eating") is a process where particles are literally engulfed by the plasma membrane of the cell. This is essentially the same process through which macrophages and other cells of our immune system remove invading particles like bacteria. Sponges are relatively simple in their organization. They are mostly asymmetrical or radially symmetrical and lack a true nervous system or muscles. Although they do possess specialized cell types, there are not organized into a functioning tissue. Because they are lacking in a tissue-level of organization, sponges obviously are acoelomate and do not possess any type of organized digestive system.

The water is drawn in through the pores by collar cells like those found in choanoflagellates dispersed by small, free-swimming larvae; about 10,000 species known

Extractions: Archaeocyaths Phylum Chordata Phylum Chordata comprises those animals most often occupying the top of the food chain, including the fishes, reptiles(included the extinct dinosaurs), reptiles, birds and mammals (including humans). The Chordates primary common feature is a notochord, a rod that extending most of the length of the organism. Lying dorsal to the gut but ventral to the central nervous system, it stiffens the body and acts as support during locomotion. More specifically, the notochordat should be present at least during some part of the organisms development. Other common morphologies include bilateral symmetry, segmented body, a well-developed coelom, a single, dorsal, hollow nerve cord, usually with an enlarged anterior end (i.e., brain), a tail projecting beyond (posterior to) the anus at some stage of development, ventral heart, with dorsal and ventral blood vessels and a closed blood system, a complete digestive system, and usually, a bony or cartilaginous endoskeleton Metazoa The first multi-celled animals ( metazoa ) evolved over 600 million years ago and can be grouped into three categories: sponge-like animals, cnidarians, and worms. The sponges, and cnidarians (corals and sea anemones), are the most primitive with about 11 specialized cell types. Worms and higher metazoa have approximately 55 specialized cells.
Extractions: Request A Brochure Tropical Marine Biology Curriculum Course Description: The biological and the physical processes interacting with tropical marine organisms including coral reefs, mangroves, and birds, will be introduced and discussed in detail. Particular emphasis will be placed on the integration of ecological processes with the biodiversity and richness of tropical habitats. An introduction to the biology and identification of tropical coral reef organisms will prepare students for underwater research activities to study the ecological processes involved in maintaining high species diversity. A series of evening presentations, discussions and debates will address reef management issues and students will conduct projects to explore areas of interest in more detail. This is a field-oriented course designed to introduce students to the techniques used in the study of biology, ecology, and physiology of subtidal organisms. Current underwater research methods are learned and implemented in underwater exercises.
