An Investigation of photosynthesis for silver beet. The aim of this investigation is to find the average rate of photosynthesis for silver beet compared to gold beet. Methods DPIP is a measure to help find the rate of photosynthesis. The rate was calculated using the slope of the absorbance/time graphs Appendix a. The rate was then calculated by dividing the change in absorbance over the change in time, an example of this can be found in appendix B. 3 Trials conducted to find out the rate of photosynthesis

nucleus and the cytoplasm. The nucleus, known as the control center of the cell, is an oval-shaped or spherical-shaped structure enclosed within a double membrane. It manages and controls all the cell’s activities. It also holds the DNA that is the genetic material for directing protein synthesis. It contains chromatin, nucleolus, and nucleoplasm. On the other hand, the cytoplasm is the content found outside the nucleus and enclosed within the cell membrane of the cell. 2. Define cytoplasm and organelles

They noted that bacterial cytoplasm is crowded, poly-disperse and in the absence of known motors, diffusion-reliant for metabolic activities. Yet, how metabolism affects the cytoplasm remained untested. Their results suggest that the cytoplasm appears like a simple viscous fluid to particles below a certain size scale (< 30nm), and like a glass-forming liquid to particles above this

In every cell there are three main parts: the nucleus, the cytoplasm, and the cell membrane. The nucleus is a spherical body usually located near the center of the cell that contains the genetic code of the cell and its purpose is to serve as the control center. Cytoplasm is the fluid medium for the many molecules and organelles the cell has. The cell membrane is the outer layer that separates the cell from its environment and controls what enters and leaves the cell. The nucleus is the control center

It also helps to anchor appendages like the pili and flagella; the wall gives the cell its shape and surrounds the cytoplasm membrane, protecting it from the environment. Cell wall of Vibrio cholera protects the cell osmotic shock and physical damage. In addition, it also confers rigidity and shape of bacterial cells. Capsule Some species of bacteria have a third

bases to amino acids, once a molecule of mRNA has been transcribed it moves out of the nucleus via the nucleus pore. mRNA will be able to pass through the nuclear pore, which goes through the ribosome, production of protein through tRNA In the cytoplasm the mRNA combines with the ribosome cellular structure on which the polypeptide chain will be built in a process called transcription In general the source of protein mainly derives from food sources with high source of proteins. The small macromolecule

undertake that data on its own, which is why we bring it into being by the activity of transcription; a messenger identified as mRNA. Once the mRNA is brought into existence, the following step is to move the mRNA out of the nucleus and into the cytoplasm then evoke ribosomes that contain a similar letter coding. The initial step of replicating DNA is through the establishment of mRNA. The DNA helicase connects to the DNA molecule opening the double helix which then lets enzymes fracture the

functions of life. Cellular Respiration also includes three stages: Glycolysis, Krebs Cycle, and the Electron Transport Chain. Glycolysis, also known as Grell, noticed Larry the glucose and his ATP friends walk into his home, the Cytoplasm(glucose and 2 ATP go into the cytoplasm). Grell invited Larry and his friends to take a seat on a large chair. Grell was secretly excited because his friends did not know that the chair had automatic wrist restraints that appear when you sit down. Larry took a

These organelles include the cell membrane, cytoplasm, cytoskeleton, nucleus, and lysosomes. Also, I share a mitochondria, ribosome, endoplasmic reticulum, and a Golgi complex with plants. First, cell membranes help me separate from my surrounding environment. Without them, I couldn't get certain nutrients and get rid of waste and many harmful materials can get inside of me. In addition, the cytoplasm is a big part to help me complete my purpose. The cytoplasm is the fluid between the nucleus and cell

surrounded by a nuclear envelope (NE). In the cells a lot of transportation occurs. One of the reasons is that nuclear proteins are synthesised in the cytoplasm, but are needed in the nucleus. Another reason is that to be able to synthesize the proteins that are required for the cell, the different RNA species located in the nucleus are needed in the cytoplasm (6). The nucleus is only able to import and export molecules through signal-dependent transport and through passive diffusion via nuclear pore complexes

6. Ribosomes - In a cell ribosomes make proteins and they pretty much just float around in the cytoplasm. In baseball players roam the field and they make plays, by catching the ball or throwing the ball to a base for an out. Ribosomes make proteins and baseball players make plays. 7. Cytoplasm - The cytoplasm in a cell hold the organelles in place and fills the extra space in a cell. Cytoplasm is just like the seats in a baseball stadium. The seats hold the crowd in place during the game

Did you know that there are over 82 schools in virginia beach? In many ways, an animal cell can be compared to a school. The Organelles’ roles in the cell align with the functions of a school in many different ways. Some examples are the Cytoplasm, Cell Membrane, and the Nucleus. One object in a cell that can be compared to a school is the Cell Membrane. In a cell, the purpose of the cell membrane is to protect the cell’s content from viruses and other harmful things . This can be compared to

also similar in many common ways. Prokaryotic cells are single-celled organisms that have no nucleus. Prokaryotic cells were found about 3.5 billion years ago. Prokaryotes have DNA in the cells that are circular because they’re located in the cytoplasm . Prokaryotic cells are smaller and less complex than in eukaryotic cells. There are no membrane or bound organelles in the cell. Prokaryotes

through the synthesis of mRNA. 2. Nucleolus- the nucleolus synthesizes ribosomal RNA (rRNA). Afterwards, these are put together with the proteins produced in the cytoplasm to create ribosomal units. 3. Nuclear Envelope- the 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

various chemicals. Even though the cytoplasm consists of 70 to 80 percent water, it has a semi-solid consistency, which comes from the proteins within it. However, proteins are not the only organic molecules found in the cytoplasm. Glucose and other simple sugars, polysaccharides, amino acids, nucleic acids, fatty acids, and derivatives of glycerol are found there, too. Ions of sodium potassium, calcium, and many other elements are also dissolved in the cytoplasm. Many metabolic reactions, including

around for longer than eukaryotes, they can adapt to more extreme temperatures. In addition, prokaryotes and eukaryotes have different ways of storing their DNA. Eukaryotes’ DNA is stored inside the nucleus. Prokaryotes’ DNA floats freely in the cytoplasm. Prokaryotes don’t have a nucleus, but eukaryotes do. Habitats and DNA differ between prokaryotic and eukaryotic

Also suspended in the eukaryotic cytoplasm are the mitochondrion and also, unique to plant cells, the chloroplasts. The mitochondria in the eukaryotic cell are responsible for producing ATP. They are known as the powerhouses of the cell. A double membrane binds them and the inner membrane is folded into partitions known as cristae. The prokaryotic cell does not contain this specific organelle either. The cytoplasm of the prokaryotic cell also contains food storage particles

Introduction As we all know, bacteria is a very complex organism and the subject can be very broad. In this essay, the focus will be on bacteria and the bacterial cell structure. Different forms of bacteria, its pros and cons, the cell structure, diseases and resistance will be explained and listed. First bacteria and cell structure is explained, and then moving on to different bacterial forms and diseases, and how diseases can be prevented or even cured. Then finishing the essay will be the conclusion

cellular respiration is in the cytoplasm and mitochondrion. The significance of cellular respiration and photosynthesis is they both help living things grow, develop, and stay alive.

the the cells are not the same so the genes expression are not the same. Prokaryotes and Eukaryotes have things that are the same in their process of gene expression. Since prokaryote cell’s do not have a nucleus, gene expression happen in the cytoplasm for them. Prokaryotes genes are transcribed on the lac operon.The lac operon functions under the promoter, which is how the lac operon gets transcribed. When the lac operon is transcribed it makes genes for proteins that each have different codes
