Cytoplasm

is semi-permeable, it allows some substances/particles into the cell but denies access to others. The cytoplasm is the fluid within each individual cell that surrounds the organelles. This is the 'place' where the organelles complete their individual tasks. The Rough Endoplasmic(RER) Reticulm is a part of a series of connected 'hallways' that carry materials to various parts of the cytoplasm. The RER has many ribosomes attached to it and it is tasked with creating proteins. The Smooth…

presence of phospholipids. The dark grainy appearance could be the ribosomes. Ribosomes appear as dark granules in the cytoplasm. Measured by rule: approximately 1 mm actual size 10 nm (image size)/(actual size)= Change 1 mm to nanometres. 1mm=1000000 nm 1000000nm/10nm= 100,000 Data based questions a. Nuclear pores. b. The pores transport molecules between nucleus and cytoplasm. This is the outer nuclear membrane because the phosphate heads (dark line) are visible and they are the…

The cell has many parts. Those parts include the cell membrane, cytoplasm, nuclear membrane, nucleus, ribosomes, mitochondria, small vacuoles, lysosomes, endoplasmic reticulum, and the golgi apparatus. We compared all of these organelles to a plastic bag, a toy animal, a large toy bear head, a highlighter, a noise maker, a medicine cup, a candle, a straw, and a box. To begin, a cell membrane controls movement in and out of the cell. It is a thin flexible layer that also supports and…

The nucleus has many different parts within its structure, in which enables it to operate. Within its structure it contains chromosomes, DNA, proteins, chromatin, nuclear membrane, . The nuclear membrane is a thin layer that surrounds the nucleus and it has pores to allow materials to enter in and out of the organelle. This part of the nucleus helps it to function because it allows the nucleus to allow important materials such as proteins, in and out of the organelle. The chromosomes are made up…

According to T.F. Gendron et al., partial amounts of the toxicity are due to a gain in function by the protein. When this occurs, the TDP-43 protein has usually shifted its location from the nucleus to throughout the cytoplasm of the cell. This abnormal accumulation of TDP-43 in the cytoplasm is not only found in neurons and glial cells of the primary motor cortex but as well as in brainstem motor nuclei, the spinal cord, and in certain associated white matter tracts (Mackenzie et al 2010). It…

Prokaryotes There are two types of organisms based cell types: Prokaryotic and Eukaryotic. Prokaryotic cells are divided into two parts: Bacteria and Archaea. Prokaryotes are much smaller than eukaryotes. Prokaryotes contain a single loop of chromosomal DNA which is stored in nucleoid. Eukaryotes DNA is found on tightly bound and organised chromosomes. Genetic expression is the process where genotypes coded in the genes are displayed by the phenotypes of the individuals. The DNA is then copied…

nucleotides are used by the cell as nutrients; they enter the cytosol through the lysosomal membrane by either facilitated diffusion or active transport. Indigestible material remains within the lysosome to form a residual body; this is removed from the cytoplasm by exocytosis and is excreted from the body as metabolic waste. On the other hand an accumulation of residual bodies contributes to cellular…

Tulip? Ms. Tulip laughed and said that is the mitochondria and it is found in large numbers in most cells and it helps with the biochemical process of respiration and energy production. She told them that all plant cells needs a space within the cytoplasm that contains fluid and this space is called a vacuoles. Altasisa then said, “wow I never knew so much is going on within a plant cell”, Ms. Tulip said I know girls we are almost there only three more things I like to talk to you about and you…

In addition, procedure part H contains the viewing of cheek cells, cheek cells are a high-caliber option for identifying the membrane, and cytoplasm of a cell. To begin, place a drop of methylene blue on a slide, then smear a toothpick amongst the inside of the cheek, lastly smear the toothpick onto the stained slide. Cheek cells just like starch cells are hard to be viewed without the addition of a staining chemical, in this case, the methylene blue will make the cheek cells have a slight blue…

A. What is the purpose of a polymerase chain reaction (PCR)? List the four main components of a PCR. (2 points) The purpose of a PCR is to make large amounts of DNA segments from just a specific DNA sequence. This method is used to scientifically prove if a suspect of committing a crime is truly the person who committed the crime. The four main components of a PCR are: DNA from a sample, nucleotides A, T, G, C, DNA polymerase, and primers. B. What is gene expression? List the two steps of…
