Cell Organelle Worksheet Organelle Nucleus Where found (plant/animal/both) In animals it’s in the center of the cell while in plants it’s found in the cytoplasm. What it does in the cell (functions) It maintains the integrity of the genes and controls the activities of the cell. Something that performs the same function in the “real world” It works like a CPU sending out messages. Organelle Nucleolus Where found (plant/animal/both) For both animal and plants it’s within the nucleus of the

INTRODUCTION An important aspect of any biotechnological processes is the culture of animal cells in artificial media. These animal cells in culture are used in recombinant DNA technology‚ genetic manipulations and in a variety of industrial processes. Now-a -days it has become possible to use the cell and tissue culture in the areas of research which have a potential for economic value and commercialization. The animal cell cultures are being extensively used in production of vaccines‚ monoclonal antibodies

sucrose solution 1.0 Abstract This experiment’s ultimate goal is to find the water potential of the potato cell. This was achieved through placing potato cores in different concentrations of sucrose (0.2%‚ 0.4%‚ 0.6%‚ 0.8%‚ 1.0%‚ 2.0%‚ 3.0% and 4.0%) solution and to observe how much water was gained or lost through osmosis to reach a prediction of the concentration within the potato cell. The results displayed that the concentration of sucrose within the potato cell is 1.7% and that as the amount

structural compartmentation of mammalian cells and the differing functions of these compartments. All mammals are eukaryotes and therefore have eukaryotic cells. These cells contain several organelles suited to a specific function they carry out within the cell. These eukaryotic cells contain a Nucleus‚ Mitochondria‚ Ribosomes‚ Rough and Smooth endoplasmic reticulum‚ Golgi apparatus and various other organelles. Most of the organelles are separated from each other by a membrane‚ these membranes

Cellphone In this technology era‚ cellphones has become very useful tool to get work done easily. Cellphones nowadays do such a significant function in our lives in several fields‚ such as‚ Business fields‚ Medical fields‚ even more importantly‚ the personal usage of them. Cellphones with the intelligent functioning of humans have become capable of doing lot of different jobs such as instant communication and many other functions of them. However‚ before cellphones invention were not able

Stem Cell paper T-T 11:20 Stem Cells and Cloning 1. Cloning is one of the most widely talked about topics in this world. The people that defend cloning believe that cloning and genetic engineering will be the answer to most of the diseases in the future. On the other hand‚ the people against it think of it as ‘ playing God ’. Cloning is unethical because people will lose their identities if their clones come into this world. We are

7.1.1 Describe the structure of DNA‚ including the antiparallel strands‚ 3’-5’ linkages and hydrogen bonding between purines and pyrimidines. DNA is made up of two strands. At one end of each strand there is a phosphate group attached to the carbon atom number 5 of the deoxyribose (this indicates the 5’ terminal) and at the other end of each strand is a hydroxyl group attached to the carbon atom number 3 of the deoxyribose (this indicates the 3’ terminal). The strands run in opposite directions

be formed so cell division is prevented. During telophase taxol causes the reversal of prophase events such as the chromosomes decondense‚ spindle disassembly‚ nuclear envelope reformation‚ the Golgi apparatus and E.R. reform and the nucleus also reforms. Cytokinesis effects are that the cell still divides for animal cells a cleavage furrow made of actin and myosin II constricts the middle of the cell and in plants the phragmoplast forms at the equator of the spindles where a new cell wall forms

Movement in and out of cells Diffusion: (mixing molecules) Molecules and ions in a liquid or a gas move continuously. The movement is quite random‚ and the particles change direction as they bump into one another. The particles collide more often when they are close together (when they are concentrated) and so they tend to diffuse‚ or spread out‚ until they are spaced evenly throughout the gas or liquid. The random movement of particles is due to their own kinetic energy. When the diffusion

can diffuse across cell membranes while some substances must be transported across the membrane by proteins. The membrane is in control of what enters and leaves the cell. However‚ certain conditions may damage the cell membrane’s structure. Beet cells‚ which are plant cells‚ have a water-soluble pigment called betacyanin‚ which is stored in its vacuole. The tonoplast‚ or the vacuole’s membrane‚ acts with the cell membrane of the cell to prevent the betacyanin
