Mr. Clark Honors Bio Period 3 10-19-13 Eukaryotic Cell vs. Prokaryotic Cell Eukaryotic cells do have a nucleus but Prokaryotic cells do not. Prokaryotic cells usually only have one chromosomes when Eukaryotic cell have more than one. Eukaryotic cells have mitochondria but Prokaryotic cells do not. Prokaryotic cells are usually unicellular and Eukaryotic cells are usually multicellular. Also Eukaryotic cells are larger than Prokaryotic cells. Both Eukaryotic and Prokaryotic cell have vacuoles

prevent easy diffusion of materials from nucleoplasm to cytoplasm. The outer of these two membranes is uninterrupted with membrane of the rough endoplasmic reticulum and thusly has ribosomes scattered along it. The gap between the inner and outer nuclear membrane is called the perinuclear space and also conjoins with the lumen of the rough Endoplasmic reticulum. This double membrane layer as well as containing many channel proteins also has many perforations where the two membranes join together to

basically looks like a stack of pancakes. The main function of the Golgi is to process‚ package‚ and deliver macromolecules‚ such as proteins and lipids. These macromolecules are sent to the Golgi after being built in the ER‚ which is the Endoplasmic reticulum‚ enclosed in tiny vesicles composed of membranes from the ER‚ so it can inspect them for flaws and discard any extra materials added during their manufacture‚ wraps them up and then targets them for packaging. The Golgi complex is especially

presence of oxygen‚ to release energy in a process called aerobic respiration. The inner membrane of the mitochondria is folded into cristae‚ which give a large surface area for attachment of some of the enzymes involved in respiration. The endoplasmic reticulum (ER) is a series of interconnecting flattened tubular tunnels‚ which are continuous with the outer

DNA. Ribosome small particles made of RNA-rich cytoplasmic which assemble the proteins. Rough endoplasmic reticulum is a large system of connected sacks that are located in the cell’s cytoplasm it’s also covered in ribosome with give’s it’s rough appearance. The rough ER transports materials though the cell and produces protein which are sent to the Golgi apparatus. Smooth endoplasmic reticulum is also a vast system

type of proteins in the cell membrane that were involved in the homeostatic imbalances of his heart cells were ATPases‚ and ATP. The lack of ATP affected the membrane pumps‚ and ATPases had stopped moving calcium from the cytosol into the endoplasmic reticulum of his heart cells. 5. F. It was important to reestablish oxygen flow to Joseph’s body because oxygen is required by cells to produce ATP. The processes that would be affected by this would be multiple cellular processes‚ including mitosis

1000 of mitochondria and each one has a double layered membrane which is similar to the cell membrane but has several folds which produces a series of “shelves” which are called cristae. Endoplasmic reticulum(ER): There are two types of ER which are called rough and smooth. Endo translates to “within” and reticulum is a term for network‚ therefore ER is a branching network inside

Golgi Apparatus: Located very near the rough endoplasmic reticulum‚ the Golgi apparatus is involved in a variety of processes. It builds lysosomes and‚ in plant cells‚ it creates complex sugars to send off in secretory vesicles. Its membrane surrounds an area of fluid where complex molecules (eg. Proteins
