Cell-tissue - CORRECT ANSWER-Aggregations of similar cells into patterns or layers, specialized for a common function. Tissue-organ - CORRECT ANSWER-Tissues combined with other types of tissue to form a structure with a more complex function than a single tissue Organ systems - CORRECT ANSWER-organs working together for common functions Animal body plans are ___________ constrained. - CORRECT ANSWERphylogenetically Which type of symmetry is described? any plane passing through the center divides the body into 2 equal halves. - CORRECT ANSWER-spherical Which symmetry is described? the animal can be divided into similar halves by multiple planes passing through the longitudinal axis? - CORRECT ANSWER-radial Describe radial symmetry: - CORRECT ANSWER-front is different than the back Describe bilateral symmetry: - CORRECT ANSWER-can be divided into 2 planes along a saggital axis into 2 mirrored poritons What is a coel? - CORRECT ANSWER-any hollow or open space What does it mean if an organism is acoelomate? - CORRECT ANSWER-the mesodermal cells completely fill the blastocoel. What does it mean if an organism is pseudocoelomate? - CORRECT ANSWER-the mesodermal cells line outer edge of the blastocoel, so they have 2 body cavitiesWhat does it mean if an organism is coelomate? - CORRECT ANSWER-they have mesodermal cells completely line the entire body cavity on all sides. Which type of cell covers the outside of the body, lines organs and cavities within the body? - CORRECT ANSWER-epithelial tissue. In epithelial tissues the cells are joined how? - CORRECT ANSWER-Closely together by tight junctions What does the closely joined cells in epithelial tissue provide? - CORRECT ANSWER-a barrier against mechanical injury, pathogens, and against fluid loss.
