Organelle

The functions of these organelles are extremely similar between the two classes of cells (peroxisomes perform additional complex functions in plant cells having to do with cellular respiration). However, the few differences that exist between plant and animals are very significant and reflect a difference in the functions of each cell.Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus,…

The purpose of this experiment was to determine the concentration of succinate dehydrogenase in six fractions made by students. Succinate dehydrogenase is an enzyme located in the mitochondrial membrane and aids in cell respirations and enzyme generation. In order to conduct this experiment, students cut a liver and through a process created six fractions. Each of the six fractions was moved to a cuvette with solutions containing different volumes and recoding the absorbance every five seconds…

allow work for cellular functions. 7. How is the structure of a lysosome related to its function? Lysosomes are membranous sacs that contain digestive enzymes also known as hydrolytic enzymes. This allows it to breakdown macromolecules, damaged organelles, and pathogens inside the cell. Phagocytosis is the process of engulfing other organisms or particles with digestive enzymes. Autophygy is when the lysosome recycle cell materials that are damaged. A key note is that the lysosome has to fuse…

she said the nucleus is a bound of organelles containing chromosome.Angelica and Altasisa was so excited that they wanted to hear more, so Ms.Tulip went on about the nuclear membrane. she said the nuclear membrane surrounds the genetic material and nucleus in eukaryotic cells. Then she started talking about Chromosomes. She told us that Chromosomes were made of protein and a single molecule of deoxyribenucleic acid. Angelica then pointed to another organelle and asked what is that Ms Tulip? Ms.…

because of the cell wall on the plants is stiff and makes the cell a certain shape. The cell membrane on an animal cell is more flexible than a cell wall that surrounds a plant cell; this lets animal cells have more varies in shapes because the organelles inside are not so tightly compacted. The cell wall around the plant cell allows the plant to stand tall and upright without the need of bones. Animals have either endoskeletons or exoskeletons to maintain their shape and structure while the…

the cells constant. As mentioned earlier, the phospholipid bilayer cell membrane is crucial in keeping the internal conditions of the cell constant. This organelle surrounds the cell, providing a selectively permeable membrane to keep the concentration of substances constant (Campbell, Neil et al. 2009). The location of function of this organelle is on the outermost layer of a cell all around it, as it encompasses the cell. Since the cell membrane is selectively permeable, it only allows…

The outer membrane shields the organelle and represses it like a skin (3). It also allows the passage of smaller molecules that contain mitochondrion sequences. The inner membrane folds over many times and produces layered structures called cristae (4). The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates…

create a shape that is similar to a barrel when it it is arranged. One of their main function is to contribute/help with processes that involve cellular activities. One example of cell division where centriole plays a role in mitosis where the organelles creates spindle fibres. These fibers allow chromosomes to be separated from each during mitosis and the can create daughter cells. The centrioles play a key role…

They are like the vacuole because working together the fridge holds the food and water, and the trash holds all the waste. Now there is one last organelle to go over the Lysosomes they breaks down old cell parts, dead cell parts, or low functioning cell parts, known as the clean up crew in a cell. The repairman that comes over sometime is like this organelle because he comes and repairs all of the broken down parts of the house like if the pipes downs in the basement need repairs then that's…

Describe the structure and function of a lysosome. Lysosomes are a cell organelle, translating as an independent structure within a cell, possessing a specific structure and function. For a lysosome its functions include; digestion of intracellular or extracellular material, nutrition from digested macromolecules and defence/protection from harmful substances. Lysosomes are variable from cell to cell in terms of shape and size but are conventionally spherical or oval shaped, 0.5µm in diameter…
