Over the past 25 weeks we have been looked at the various parts of the so-called Simple Cell. For your convenience I am listing each week’s article below along with the link to that article. You may wish to bookmark … Continue reading
Today we are making a huge jump from the nucleus in the center of the cell to the outside of the cell membrane. Here we are going to take a look at the cell’s second language (the first language being … Continue reading
Over the last eight segments in the Simple Cell series we have been looking at the cell nucleus and its major components. The last of those major components is the nucleolus. The nucleolus is a non-membrane structure found in the … Continue reading
In the last episode of this series, we took a very brief look at The Many Faces of RNA. We saw that RNA is involved in the reading and decoding of DNA and in governing the process of protein synthesis … Continue reading
The past two weeks we took a brief overview of mitosis and meiosis, the processes of cell division. This week we will return to examining one of the three major macromolecules in the nucleus and cell that are indispensable for … Continue reading
Last week we did a brief overview of the asexual cell division process known as mitosis. Mitosis is the process that promotes skin and tissue growth and accounts for over 99% of the cell division processes that occur in the … Continue reading
As we have been looking at the nucleus for the past couple of weeks, I realized that so many of the functions of the various parts of the nucleus are involved in cell division. Therefore, before we move on to … Continue reading
There is no doubt that the DNA and chromosomes are considered to be the most exciting and important part of the cell nucleus. However, a vital and sometimes overlooked part of the cell nucleus is the nuclear lamina. The … Continue reading
Throughout the series on the Simple Cell we have seen how everything is organized and in its expected place and function. Nothing in the cell is left to chance. The nucleus is no exception. In fact, in some ways, the … Continue reading
In Part 16 of this series, we briefly discussed the nuclear membrane and that its main function of compartmentalizng the nucleus off from the rest of the cell. Additionally, we mentioned that the nuclear membrane contained pores that help in … Continue reading
The difference between prokaryote and eukaryote cells is the presence of absence of a nucleus. Prokaryote cells lack a nucleus and eukaryote cells. Their chromosomes are loosely grouped together in the center of the cell. In Eukaryote cells the chromosomes … Continue reading
Two weeks ago we featured the process of photosynthesis in Photosynthesis – Simple Cell Part 13. Today, we are going to look at the chloroplast, where photosynthesis takes place. Evolutionary scientists believe that photosynthesis and chloroplasts are among the earliest … Continue reading
by David Demick Mitochondria are small, membrane-bound organelles serving as energy generators in eukaryotic cells. Most cells have hundred to thousands of them, depending on their energy needs. Mitochondria are very good at what they do—they generate about 95% of … Continue reading
Normally on Fridays, I post an original article on the Simple Cell along with Articles 4 Kids. Due to personal circumstances, I was not able to get my article on the Simple Cell written in time for posting. Therefore, I … Continue reading
This may sound odd to some to people, but over the years of cellular study, I have developed several favorite cell structures. The reason for my favoritism lies in the complexity of these structures and how they stand as firm … Continue reading
