Question

1. Why is it important to know the limitation of a technology? 2. List the 5 steps of directional cell walking when starting with a cell in suspension 3. Describe the mechanisms of how a normal cell locomotes in a cell culture plate. 4. What is a filopoidum: what is its purpose for the cell and what is it comprised of? 5. Explain how social systems of cells increased the fitness of the organism.

Answer 1

1. Advancements can only occur if we know the limitations of technology i.e. up to what extent should we surround ourselves with the technology and come up with inventions that promote fitness, humanity and save time as well, rather than developing nuclear bombs, software malware, etc.

3. The inner surface of the cell culture plate is usually treated with specific polymeric proteins to which the extracellular cell moieties attach thus providing surface anchorage to grow and spread.

4. Filopoidum or filopodia are cell surface protrusions or antennas that cell a cell to detect the changes in its environment. Thus it can be stated that they act like probes which play major role in cell healing, motility, etc. These protrusions are usually 0.1-0.3 micrometer in diameter and consists of actin filaments.

5. A cell is the basic structural and functional unit of life. The cells interact with each other to maintain homeostasis in an individual. Any miscommunication or signal inhibition or external mutations that alter these cell signaling which ultimately can lead to immune disturbance in the host rendering compromised fitness.
