Functions of Eukaryotic Cell Organelles and Their Importance Essay

Exclusively available on Available only on IvyPanda® Made by Human No AI

Introduction

People’s organisms consist of various cells that help to perform different functions. Cells are microscopic units that help all the organisms on a planet to exist and to survive. Cells can come in multiple shapes, sizes, and formations with the same essential activity. The main objective is to understand how eukaryotic cells of organelles function. An organelle is a membrane contained in a cell that implements its specific important task.

Main Body

The journey starts with the observation of each organelle and its function description. The first organelle is the cell wall, whose main functions are to give the cell support and provide a specific structure and shape, protecting it against any damage or injury (Carlton et al., 2020). In other words, a cell wall ensures molecules’ strength and ability to transport in and out of a cell. The cell membrane, in turn, has two functions: maintaining undesired substances out of the cell and allowing adequate nutrient transportation into the cell (Carlton et al., 2020). The cell also has its control center, where the nucleus is a responsible character whose primary function is to store genetic information (Carlton et al., 2020).

The processes of photosynthesis and the release of oxygen are as important as the storage function of the previous organelle. These functions are ensured by chloroplasts, which produce energy for a cell through these processes (Carlton et al., 2020). In the same way, mitochondria provide energy, functioning as a generator of power for biochemical reactions (Carlton et al., 2020). When it comes to such vital functions as the creation of peptide bonds and the decoding of genetic messages, the organelle of the ribosome is mentioned (Carlton et al., 2020). These two functions can be found in ribonucleoprotein particles of different sizes, which have subunits of several ribosomal proteins (Carlton et al., 2020). It is necessary to analyze the further functions of organelles that ensure the presence of protein in cells.

Another crucial player in the cell’s life is the endoplasmic reticulum, which produces proteins to provide the cell’s full functioning. There are different endoplasmic reticulum organelles, which, depending on their type, can produce such substances as carbohydrates or lipids (Carlton et al., 2020). Continuing the journey, it is worth mentioning that the Golgi complex, which works with proteins like the reticulum, prepares them for usage inside and outside the cell (Carlton et al., 2020). Vacuoles, in their turn, perceive and remove the waste products in the cell (Carlton et al., 2020). When a cell wants to dissolve any material, it uses lysosomes’ functioning (Carlton et al., 2020).

The cell engages in passive and active modes to undertake the function of substance transportation. Passive transportation is the process of substances crossing the plasma membrane, using no energy from the cell, because they go from the area with higher concentration (Carlton et al., 2020). Meanwhile, active transportation happens when there is a need for energy to move, so the substance moves from the area with a lower concentration to a higher concentration (Carlton et al., 2020). The cell also goes through the process of division, where the outer membrane nips inward to create a new cell (Carlton et al., 2020). Consequently, the need for a division process is justified because the organisms need to grow and renew. Although organelles are just subcellular structures, the journey proves that they implement a crucial task – give the cells the possibility to function in their surroundings.

Conclusion

Conclusively, organelles are small compositions located inside the cell and have crucial functions. The cell has to go through different processes to continue the living process. These processes are ensured by organelles’ constant work and integrated input. Due to such functioning, the cells can gain different shapes and sizes and implement various activities. Eventually, the organelles’ importance is revealed by ensuring the organisms’ existence and survival.
