Cell Specialization: All living organisms are composed of one or more cells - this statement is probably one of the most important principles of the Cell Theory by Theodor Schwann and Matthias Schleiden. This makes sense given that the body of multi-cellular organisms are made up of them but are not all identical Because cells are microscopic, difficult to visualize in three dimensions, and exceedingly complex in function, most teachers draw analogies to help students grasp their significance. It is common to hear teachers draw analogies between cells and cities, schools, and factories you've probably heard of stem cells by now and you probably know that every cell in our body whether it's a muscle cell or a nerve cell or a skin cell or a red blood cell or any other type of cell really they all came from a common group of stem cells during development so all of these really really specialized cells like this muscle cell here with its little contractile proteins and this. A group of cells that are assigned one particular function are said to be specialized cells. Pluripotent cells (cells that are capable of differentiating into other cells) undergo a process of differentiation to form specialized cells that are said to be uni potent So in this analogy we can assume that the students before the examination are just like cells before being specialized, and the students after the examination (furthering their studies or working) are just like cells after being specialized to suit their functions. SO, WHAT IS CELL SPECIALIZATION? Cell specialization (or modification or.
Sex chromosomes—particularly the human Y—have been a source of fascination for decades because of their unique transmission patterns and their peculiar cytology. The outpouring of genomic data confirms that their atypical structure and gene composition break the rules of genome organization, function, and evolution. The X has been shaped by dosage differences to have a biased gene content. Cell Specialization: Develop an analogy between cell specialization and specialization of roles within your community. Describe your analogy to family members. 1.16 Case Study: Cell Wars: Consult with adult family members to find out the answers to the following questions Cell Specialization: PLANT CELLS.

Eukaryotic Cell: Definition, Structure & Function (with Analogy & Diagram) Prokaryotic Cells: Definition. Cell Analogy Example This is a slideshow I created as an example of an analogy one could use to explain the function of organelles in a cell. The slideshow runs on a continuous loop in the classroom (7th Grade, Georgia) while the students create cell analogies of their own
A biology exam preparation portal. 1) Nucleus: is comparable to the headquarters of a factory where managers will give timely instruction for the smooth running of the factory.It is separated from the rest of factory especially working area. Inside cell, nucleus is the instruction centre, where instruction for the synthesis of products or proteins is coded CELL SPECIALIZATION occurs because many forms of life have many levels of organization. In most plants, animals, and fungi, cells are organized into different types of tissues. TISSUES are groups of cells that carry out a common function. That's why the factory analogy breaks down as cells become more specialized. Not all cells have to.

A cell that contains a nucleus. The other type of cell is called a prokaryotic cell, which is what bacteria cells are. Prokaryotic cells do not contain a nucleus. Eukaryotic cells are found in the eukaryotes, which include animals, plants, fungi, and protists. Eukaryotic cells also contain many other types of structure 2. Cell Specialization Cell specialization is the process that is responsible for the production of cells with different traits at different positions. This process sees cells (embryonic cells) changing from their simple form into more specialized cells both in structure and function
Analogies to machines are widely used in molecular biology to understand the nature of cellular processes. The DNA replication apparatus, spliceosome, nuclear pore, and ribosome all have substructures, moving parts, and integrated assemblies like conventional machines (Cell, 1998).Yet other biological systems, which might seem machine-like, on closer examination operate on very different. Cell specialization involves two main steps: determination and differentiation. The cells produced during the first few divisions of the zygote are known as embryonic stem cells. can be compared to the structure of an ecosystem with its different levels of organisation. explore this analogy.....use the internet. Provide a written.
It is believed there is a relationship between analogy and the mental functions and processes such as, comprehension, inference, decision-making, planning and learning. Human cognition which includes the capacity of abstraction, generalization, specialization and reasoning is the foundation of the creation of analogy in speech Cell Specialisation and Organism Organisation. Multicellular organisms contain a wide range of different cells. Every cell is specialised to perform its function as best as possible. There are many differences between different cells specialised for different functions The cell's vacuole contains water that stores waste products and nutrients. In our analogy, the vacuole is the equivalent of the warehouse. It increases tension in the cell walls by pressing against them, thus making the plant stiff. If the vacuoles don't have enough tension, the plant wilts

Cell Analogies - After modeling and practice, the students will determine at least three similarities and differences between plant and animal cells by using their scientific reasoning skills. Cell Analogies Collage- This project challenges students to make original functional analogies between cell structures and everyday objects Cells Come From Other Cells. The third part of cell theory, that living cells come only from other living cells, seems obvious to us today, but this thought wasn't universally accepted in the 1800's
When you find oil on somebody's property, it doe Christoph Lengauer makes an analogy stating that cells should be treated with the same value as oil. He states, Why not treat valuable cells like oil? When you find oil on somebody's property, it doesn't automatically belong to them, but they do get a portion of the profits. (p. 267) An analogy is a comparison between two things—for instance, a comparison of a heart to a pump. We communicate in analogies all the time, as they allow us to express our ideas or to explain complex matters in an understandable and motivating way. It allowed for a continuous workflow, worker specialization, less waste and a higher quality.

Perhaps the most common synaptic specialization of dendrites is that which Spanish anatomist Ramon y Cajal referred to as espinas, since they resembled the thorns on a flower stem. These spines are frequent on the dendrites of the principal cells of most brain regions, notably on the pyramidal cells of cerebral cortex and the Purkinje cells. -Cell Analogy - How is a cell like a cookie factory?

Dendritic cells (DC) represent a heterogeneous population of antigen-presenting cells that are crucial in initiating and shaping immune responses. Although all DC are capable of antigen-uptake, processing, and presentation to T cells, DC subtypes differ in their origin, location, migration patterns, and specialized immunological roles. While in recent years, there have been rapid advances in. A cell's endoplasmic reticulum (ER) contains a network of tubules and flattened sacs. The ER performs multiple functions in both plant and animal cells. Endoplasmic reticulum has two major regions: smooth endoplasmic reticulum and rough endoplasmic reticulum. Rough ER contains attached ribosomes while smooth ER does not In humans and other animals with complex development and tissue specialization, most of the large-scale changes cause such profound problems with development that the embryo does not develop correctly and is spontaneously aborted. By analogy, think about the complex system of an automobile. If you make a large, random change to a.
