1a. What are the two major parts of the cell? The two major parts of the cell are the nucleus and the cytoplasm. 1b. How is the role of the nucleus in a cell similar to the role of the captain on a sports team? The role of the nucleus in a cell similar to the role of the captain on a sports team because nucleus is the middle part of an object or group‚ forming the basis for its activity and growth. 2a. What is the function of lysosomes? The function of lysosomes is cellular organelles that contain

Eukaryotic cells have similarities and differences. They can be found in different places. They have different ways of functioning and can be made up of different things. But just how they are very different they have some similarities that can in a way unite them and make them a part of the of a cell family. With their differences and similarities‚ they’re just here for one solemnly purpose‚ to serve whatever type of organism they are present in. A Prokaryotic cell does not have a nucleus present.

Lab 4 – The Cell Answer Key Procedure 4.3 Draw a picture of a single Elodea cell and label all visible structures. See the diagram in your lab manual. Without staining‚ the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts. Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.

How is the structure of cells related to their function? Cell structures come in various shapes and sizes dependent on their location within an organism and what life sustaining process it carries out. These can range from the globular protein of a red blood cell‚ designed to carry four oxygen molecules at a time to the tail like flagellum of a bacteria designed for mobility and penetration of organs within a body. There are two main types of cells‚ eukaryotic cells which are generally plant

Eukaryotic cell proteins? * Because when eukaryotic proteins are expressed in prokaryotic cells problems like been unstable‚ no biological activity and prokaryotic contaminants ( pyrogens) can occur. * Also to make the protein as natural as possible * The same expression vectors as we need for pro * We don’t need shangdolron coz that only for pro Transformation: in Eukaryotic cells: in humans means that difference in growth characters of cells‚ for example‚ the cells get transformed

Biology- Animal cell The NUCLEUS is the largest organelle in the majority of cells. It contains genetic information in DNA‚ which is responsible for the cells unique characteristics. The nucleus is separated from the rest of the cell by.... ...The NUCLEAR ENVELOPE is used as a barrier which separates the contents of the nucleus from the cytoplasm‚ all in all keeping the DNA safe and intact. The nuclear envelope regulates the flow of substances into and out of the nucleus. The NUCLEOLUS is an important

Cell: The cell is the basic structural‚ functional and biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing‚ and are often called the "building blocks of life". Discoverer: The cell was discovered by Robert Hooke in 1665. The cell theory‚ first developed in 1839 by Matthias Jakob Schleiden andTheodor Schwann‚ states that all organisms are composed of one or more cells‚ that all cells come from preexisting cells‚ that vital functions
Free Cell Eukaryote Bacteria
Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name‚ (also spelled "eucaryote‚") which comes from the Greek word referring to the nucleus. Animals‚ plants‚ fungi‚ and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the

Cell Fractionation * Cell Fractionation: takes cells apart and separates the major organelles and other subcellular structures from one another. * Tissue cells are the first one to be homogenate or broken apart. * Plasma membranes are broken up so that there internal contents spill out and mix together and this is called homogenate. * Homogenate is in spun in a higher rate of speed in a process called centrifugation. And that speed can vary that why it’s called differential
