Journey Through a Cell

Eukaryotic cells have one thing in common that is a nucleus and organelles enclosed by a plasma membrane. The cells are found in a variety of living things including animals, plants, fungi, and protozoa. Inside the cells, the nucleus and the organelles perform distinct functions to keep the cell alive as well as meeting its purpose. One cannot imagine how the complex unit of life can feed, replicate, and perform its functions. The smallest unit of life is essential to sustain lives, and for instance, if cells of our vital organs stopped functions the ultimate result is death. This essay will discuss the structure, organelles, and the function of hepatocytes.

Hepatocytes are also known as liver cells, and they perform essential functions in the body. The liver cells play a crucial role by performing several metabolic and chemical reactions that are vital to living (Umemura, Yuichiro, Shinnosuke,

Microfilaments look like thin solid rods that have a structural function. The microtubules carry functions such as transportation of granules, vesicles or organelles such as mitochondria as well as offering structural support to the cell. The mitochondria are essential organelles in all cells because it is a powerhouse for energy used in all cellular functions. In liver cells, they have numerous mitochondria because of the metabolic activities that are carried out within the cell. The mitochondria resemble beans with an oblong shape, and they are found in the cytoplasm. Having seen the above organelles, at the center of the cell, there is a specialized organelle known as the nucleus whose function to process information as the administrative center. After the various activities that take place inside the cell, wastes, worn out organelles and other particles are broken down

    b-The nucleus is an organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes. The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle.…

    The Cytoplasm is a jelly- like liquid present in a cell. It is a colourless substance and generally alluded as cytosol (means substance of the cell). It encompasses the cell membrane, nucleus and cellular organelles.1 Its main function is the movement of cellular organelles inside the cell. It also provides shape to the cell.…

    Lysosomes are small organelles that break down food particles and worn-out cell parts. Most of the cell’s energy is produced in the mitochondria. Cytoplasm is gel-like fluid which many of the organelles are found. Ribosomes function as factories to produce proteins which can either be attached to the endoplasmic reticulum or float in the cytoplasm. The golgi apparatus receives materials from the endoplasmic reticulum and send them to other parts of the cell…

    These nucleoli are responsible for ribosome production. If the nucleus were to suddenly malfunction, this would mean that the cell would have no directions, and nothing to direct them, so all activity would completely stop. Cell Membrane: The cell membrane is the organelle in the cell which determines what can come in and out of the cell. The cell membrane itself is a double layer of phospholipids, and this appears…

    Centrosomes are also present and they contain important spindle fibers which develop during the process of cell division. Main Functions: Endoplasmic Reticulum- a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum) involved in the transport of materials. Nucleus- a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material (Contains: nuclear pore, nucleolus, nucleoplasm, and nuclear envelope) Golgi Apparatus-…

    Eukaryotic cells are known for its organelles variety. Each organelle has its function so consequently each organelle differentiates from one another by its content. In this lab, the cells from a cauliflower were studied with the purpose to separate nuclei and mitochondria content from a solution. To achieve the results, the cauliflower solution had to go through differential centrifugation, microscopy, and succinate dehydrogenase assay.…

    As the largest organelle, and the first to be discovered [1], the nucleus is the control center of the cell. Given its name by Scottish Botanist, Robert Brown, the nucleus is responsible for all cellular processes in eukaryotic cells and usually fills approximately 10% of the cell's volume [1]. The reason for this organelle's large size is because of the DNA it contains. In fact, each human contains approximately six feet of DNA which is tightly packed and highly organized by proteins, the majority of it stored in the nucleus [1]. With this DNA, the nucleus produces needed proteins which are then used for cell growth, reproduction, and the overall functioning of the cell [2].…

    Mitochondria are to produce the energy currency of the cell, ATP, through respiration, and to regulate celluar metabolism. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creaks layered structures called cristae. The main function of the mitochondria is the production of energy during the production of adenosine Triphospate (ATP). Mitochondria DNA is cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use ATP.…

    Introduction: - Mitochondria is a double membrane organelle that is found in all eukaryotic organism. There are some evidences that proves that some of the eukaryotic organism lack this organelle but there is no true evidence which says that this specific organism completely lacks mitochondria. Mitochondria is also known as a power house of the living body cell. It stores energies in the cell and releases when its needed. Every organelle in Mitochondria have their own specific roles which helps in storing energy (See Figure 1 for details).…
