- This question is about cells & organelles. Why do you think there was so much emphasis put on those initially? How does it relate to the organ systems & the overall body? Please answer each question in paragraphs.Each level of biological organization has emergent properties that arise from interactions at a lower level. For example, cells have a capacity for inheritance that the molecules making up the cell do not. Can you think of an emergent property of a tissue? Of an organ that contains that tissue?Each of the following is a main idea of the cell theory EXCEPT: O all cells are similar in structure and function. O all organisms are composed of cells. O all cells come from pre-existing cells. O the cell is the basic unit of life.
- Which tenet of the cell theory is supported by the concepts of mitosis and meiosis? O Cells are the fundamental unit of life. All living things are made up of cells Living things are made up of at least one cell • Cells come from pre-existing cells.This activity will help you remember the functions of select cellular structures. Choose 5 or more cellular structures and write an analogy about how those structures function together in an everyday system. The analogous system should be something you already know (e.g., football organization, factory, etc.). Be sure to use only one every day system that incorporates all 5+ cellular structures (and not a different, unrelated system for each structure). Be sure to: Include 5 or more cellular structures Relating all the cellular structures to a single everyday system Accurately representing the analogous functions of the cellular structures Be creative and uniqueWhich structure is at a different level of organization from the other three? O liver O kidney O heart O ciliated cell
- Which of the following statements is correct about the three classical postulates of cell theory: I. All organisms are composed of one or more cells. (Virchow)(1858) II. The cell is the basic unit of life in all living things. (Schleiden & Schwann)(1838-39) III. All cells are produced by the division of preexisting cells. (Virchow)(1858)what is cell? and it function what make it differentTissues, Organs, & Systems Multi-cellular organisms have many cells that work together in specific ways, each group performing certain functions. When each group does its part, the organism gets everything that it needs. A Tissue is a large group of cells that all have the same purpose or function. Each kind of cell has unique characteristics such as shape, size, flexibility, color and texture. Nerve cell combined with other nerve cell to make nerve tissue. Muscle cell combined with other muscle cell to make muscle tissue. Bone cell combine with other bone cell to make bone tissue. An Organ is a group of tissues that work together to do a certain job for the body. Some of the human body’s organs include the stomach, lungs, heart, kidneys, brainand liver. Some of a plant’s organs include roots, stems, fruit and leaves. When several different organs join to meet the organism’s needs, they are working together in an organ system. There are several different organ systems constantly…
- eory, and Microsco Select all of the following that are part of cell theory. O All cells have the same organelles. O Living cells come from other cells. O All living things are made of cells. O All cells live forever. O Cells are not actually alive O Cells are the basic unit of structure for all life.What is this? What special ability does it have? Does it have organelles to perform this activity?Which of the following are a part of the cell theory? All of the other answers Cells can arise only by division of preexisting cells Cells contain genetic information The cell is the structural unit of life All organisms are composed of one or more cell
