Bacterial And Eukaryotic Cells Similarities
Eukaryotic cells and bacterial cells share some similarities, however, also contribute many differences due to the size difference between the two different cells. Due to the size difference between eukaryotic and bacterial cells, structural characteristics such as the presence of a nucleus, endomembrane system, cytoskeleton, membrane-bounded organelles, number of chromosomes, and differences in cell walls occur. All bacteria are one-celled organisms. There is no form of bacteria that contains a nucleus. However, this is not the case in eukaryotic cells. The eukaryotic cell’s most important component is the nucleus. This is a compartment that is surrounded by membranes that houses the DNA that is eventually divided into chromosomes. The nucleus protects the eukaryotic cell from damage that could occur on a day-to-day basis. …show more content…
Therefore, eukaryotic cells are composed of membrane-bound organelles that help to carry out these processes. A structure that is unique to the eukaryotic cell that helps to carry out these processes is the endomembrane system. The endomembrane system is a network of organelles that work together in the manufacturing and transporting of cellular products. The main structures involved in the endomembrane system are the rough endoplasmic reticulum (rough ER), smooth endoplasmic reticulum (smooth ER), and the Golgi apparatus. The rough ER is the location of the majority of the ribosomes found in the eukaryotic cell. These ribosomes are responsible for the synthesizing of many proteins in the cell. The smooth ER is responsible for producing lipids and detoxifying the cell environment with enzymes that make the toxic materials easier for the body to

513 Words | 3 Pagesthe nuclear membrane is a double membrane structure that acts as a barrier separating the nucleus and the cytoplasm. 4. Mitochondria- termed as the “powerhouse of the cell,” the mitochondria is responsible for the production of ATP and cellular respiration. Energy is converted in this structure and used for the different activities that take place within the cell. 5.

The mitochondria gives the cell energy just like the crowd does at a baseball game. The crowd gets the players pumped up by cheering and yelling.
Summary Of Organelles As Organism
288 Words | 2 PagesOrganelles as organism is from The Lives of a cell authored by Lewis Thomas. Thomas uses a unique writing style that is very recognizable and different from the others. This helps us to appreciate our diversity as human beings demonstrated by our abilities to write differently. As a reader one is able to form an image of who Thomas is by how he expresses his feelings and attitudes. When this text was written a lot of people, mostly scientists, thought and had knowledge of different things than they do now.
White Houses: The Gates Of The White House
418 Words | 2 PagesA cell is like the white house,It has many areas that work differently and have their own job’s to do just like a cell itself . The gates of the white house can be known as the cell wall because the gates surround the white house protecting it from bad things or people who shouldn’t go into the area or premassis. There are people who make things such as clothing or tools inside the white house so this area can act as the smooth endoplasmic reticulum,as for the rough endoplasmic reticulum,the doors can be referred to this because the doors only let certain people into the white house such as the president and his family,the security guard’s because they need to protect the area from bad people and the senators to discuss their work.

354 Words | 2 PagesThe Yertis Pestis bacteria cell is a bacteria cell, which means that it is a very small cell. It’s smaller than a lot of plant and animal cells, but bigger than most viruses. The cell has relatively few organelles. It has a cell membrane, cytoplasm, and ribosomes. Instead of a nucleus, it’s genetic material is floating around in a tangled string in the cytoplasm (Cells and Heredity 24).

543 Words | 3 PagesEven though we cannot see cells without a microscope, they are the basic unit of life and they exhibit all of the characteristics of living organisms. They can exist individually, as do bacteria, or they may work together, taking on specialized tasks to create a more complex organism. However, all living organisms share certain characteristics, which are discussed below. Cells are made of cytoplasm.

972 Words | 4 PagesGolgi bodies function as the packaging department of the cell because it prepares proteins and lipids for transport and use outside of the cell. The vacuoles serves as the storage room for the cell and endoplasmic reticulum is the conveyor belt that moves materials around the cell. 2. How are plant and animal cells
Assess The Difference Between Prokaryotic And Eukaryotic Cells
738 Words | 3 PagesThe larger, more complex cells are eukaryotic cells because they have more organelles with more functions. The smaller, simpler cells are prokaryotic because they have fewer functions and organelles. My box represents a eukaryotic plant cell. One of the advantages of having a box as a plant cell is that it represents the cell
Hypoxic Injury Research Paper
453 Words | 2 PagesIt is important to look at the causes of cell injury because this shows us how and why people end up with certain diseases. The body must maintain homeostasis at a microscopic level in order to function properly at the macroscopic level. We have seen that there are many ways for cells to be injured and how important it is to help our bodies maintain
Cell Nucleus Lab Report
633 Words | 3 PagesWhat we knew in last 100 years about chromosomes has completely changed now with this new discovery. We had thought the nucleus is made up of tightly wrapped proteins called histones which form chromosomes. “New research shows that not only the the chromosomes contain 25,000 or more genes it contains also a mysterious structure scientists have found a sheet-like structure that occupies the 47% of the chromosome” (BEC Crew). For the last century, we thought the cell nucleus was made of complex DNA and histone proteins. The reason we did not know much about the cell nucleus is because the chromosomes were only visible during cell division that is during meiosis and mitosis, where the chromosomes are tightly packed to form supercoiled like structures which were visible under a microscope.

Prokaryotes Vs Eukaryotes
1138 Words | 5 PagesFirstly, the majority of prokaryotic cells and eukaryotic cells are single-celled, although prokaryotes have a diameter measuring up to 5 millimetres, which is a similar size to the nucleus of a eukaryotic cell and eukaryotic cells are usually 10-100 millimetres in diameter (1) (2). Eukaryotic cells can also be found in colonies and multicellular species (1). As shown in figure 1,

860 Words | 4 PagesThe nucleus is generally in the center of a cell. A typical cell nucleus is so small that ten thousand could fit on the tip of a needle. One strand of DNA is around 6 feet long. This mean that 6 feet of DNA fits inside the nucleus, which occupies about 10% of a total cell (https://en.wikipedia.org/wiki/Cell_nucleus), of a microscopic cell. For this to happen eight separate histone protein subunits attach to the DNA molecule to

When waste products are present the cell membrane gets rid of it and the cell membrane allows important things inside . A great example of what the cell membrane allows in or out is water and oxygen. Specific molecules are only made to enter the cell which is also called semipermeable. Molecules can be passed by active transport or either passive transport.
