Biology: Answers to Questions

Definitely, without the invention of the microscope, the cell theory would not have been possible. To further understand such a claim or statement, it would be essential to highlight the events which led to the development of the aforesaid theory.

Without the efforts of Robert Hooke as well as the insights of Anton van Leeuwenhoek, individuals would not have learned to appreciate the notion that large objects which may be seen with the naked eye actually has minute subcomponents which may only be seen through the use of a specialized viewing apparatus (Chiras, 2005).

Of course, through the ability to see such smaller components, otherwise referred to as the cells, experts began to develop concepts and even assumptions regarding the importance or characteristics of the cell. Furthermore, both Theodor Schwann and Matthias Schleiden’s endeavors involved the analysis of cells in various tissues (Chiras, 2005), which would have been impossible without the use of basic techniques in microscopy. Proving that the microscope is essential to the development of the cell theory is not a matter of biological knowledge but is rather more of argumentative logic.

Hence, the abovementioned claim could actually be further supported with the following statement: without the cell being discovered through the use of the microscope, as accomplished by Robert Hooke, how would a theory regarding its role and presence throughout organisms arise? Part B Eukaryotic and prokaryotic cells have various identifiable similarities and differences. In terms of similarities, the most apparent would be the presence of plasma membranes and cytosol in both (BioInquiries, n.d.).

As for differences, it is evident that the prokaryotic cell lacks certain features of the eukaryotic cell. In particular, the prokaryotic cell, unlike its eukaryotic counterpart, does not have compartmentalized components or organelles as well as a proper nucleus. It is probable that the advanced structural components of the eukaryotic cells have been developed due to the need for more complex features among organisms.

It is true that prokaryotic cells are efficient and functional up to a certain extent, but it would be appropriate to assume that the presence of compartmentalization resulting in a superior placement and arrangement of components would lead to even greater efficiency and functionality. As production lines makes the creation of items orderly and efficiently through the separation of areas for certain steps of the process while maintaining interconnectivity, the eukaryotic cell allows for the most vital processes within the cell to occur in a similar fashion.

For example, necessary particles from outside the cell are carefully passed on through other portions until such may be eventually utilized in the generation of energy as well as in the maintenance of other components (Campbell ; Farrell, 2009). Part C C1 In ensuring that the data within the DNA is found throughout virtually each cell in the body, it would be possible to ensure that such cells would multiply and develop appropriately.

Specifically, it is important to point out that the manner in which growth occurs as well as differentiation is accounted for or mainly driven by the aforesaid information within the genetic material. Given the complexity of humans in terms of structure, having only one repository for DNA may bring forth considerable repercussions. If the sole repository would be compromised or damaged significantly, then the possibility of survival and continuing normal growth would be unlikely.

However, by having copies of the DNA in each cell, if such damage would occur then it would be initially confined to a particular cell and would not immediately compromise the entire individual. In relation to this, the presence of only four bases in the DNA may lead to doubts for some individuals as such bases supposedly results to countless variation; one must take into account the number of possible combinations well as the length of the entire sequence to appreciate the thought of having innumerable genetic patterns.
