She wondered how she got another pimple when she already pricked it a few days ago. What principle of the cell theory is related to this? Provide a brief explanation as to its relationship with the principle of cell theoryinvolved. ThanksCell specializations are usually a modification or elaboration of one of the basic cell functions. (True or fa1se?)
- 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)Is red blood cells(erythrocytes) considered true cells histologically? Why or why not? ExplainCarina is a 15-year-old girl who presents with acute-onset skin eruptions on her face. A punch biopsy obtained from her normal skin is shown in the figure below. Which cells synthesize the structure labeled by the black arrow in the figure? Describe its characteristics.
- What is the role of cilia and how does it interact all over the body? Microtubules have a wide variety of functions and locations, which includes cilia. Defects in Cilia can manifest in many different phenotypic defects including Kartagener's syndrome which effects organ placement, bronchitis, and sinituis. What is the role of cilia and how does it interact all over the body?Comment on the following (1922) quote fromWarren Lewis, who was one of the pioneers of cell biology.“Were the various types of cells to lose their stickiness forone another and for the supporting extracellular matrix,our bodies would at once disintegrate and flow off into theground in a mixed stream of cells.During a microscopy exercise in the anatomy laboratory,a student makes the following observations about a tissuesection: (1) The section contains some different types ofscattered protein fibers—that is, they exhibit differentwidths, some are branched, some are long and unbranched,and their staining characteristics differ (some are seenonly with specific stains). (2) Several cell types withdifferent morphologies are scattered throughout the section,but these cells are not grouped tightly together. (3) Theexamined section has some “open spaces”—that is, placesbetween cells and the observed fibers in the section thatappear clear with no recognizable features. What type oftissue is the student observing? Where might this tissue befound in the body?
- The cell theory is not applied for...........If a starfish sustains damage to an arm, it often grows a new one, as long as part of the central disc is still attached (known as regeneration). If a gecko loses its tail, it may regenerate a new one. If a person damages their spinal cord, mobility is often impaired. Which type of cell is less likely to go through the cell cycle after being damaged— starfish arm, gecko tail or human spinal cord? Explain in terms of the cell cycle.Even though cytokinesis is included with Mitosis, we generally consider it to be its own phase. Why? by the time cytokinesis occurs, the cell has already split by the time cytokinesis occurs, the cytoplasm has already split by the time cytokinesis occurs, the nucleus has already split by the time cytokinesis occurs, the cell has copied all of its chromosomes
