CELL BIOLOGY 2
CELL BIOLOGY
The cell is the basic functional unit of all living organisms (Alberts et al., 2018). It is,
therefore, the smallest unit of life. Cell biology is the branch of biology that deals with the study
of the structure and function of the cell. Cells contain cytoplasm, which is enclosed within the
membrane of the cell. The cell membrane contains many biomolecules, such as nucleic acids and
proteins. Most cells can only be seen under a microscope since they are small and numerous. The
human has an average of 40 trillion cells in the body. Organisms can be classified into two groups,
which are unicellular such as the bacteria which contain a single cell or multicellulars such as
plants and animals. Cells, on the other hand, can be categorized into two types. A cell can be either
prokaryotic or eukaryotic.
Prokaryotic cells
Prokaryotic cells are cells whose nucleus is not enclosed (Marshall, 2017). Such cells
include bacteria and archaea. Both organisms reproduce by binary fusion. Prokaryotic cells engage
themselves in several activities, which are essential for their survival. The main activity they
engage themselves in is conjugation. Conjugation is a fertility factor that allows bacteria to
manufacture and produce a pilus. The pilus allows the bacteria to transmit DNA to other bacteria
without the F factor allowing it to survive in new environments.
Bacteria is the most prominent type of prokaryotic cells (V.K., 2016). This is because the organism
occurs in different shapes and sizes. Bacteria mainly occur in spherical or even rod shapes. Bacteria
only have three structural features. The first structural feature is the flagella. This is a tail-like
structure that is responsible for movement in bacteria. Ribosomes are used to synthesize RNA to
proteins. The nucleoid is used to hold all the genetic matter in the organism to a circular structure.
