Lab 2: Animal and Plant Cells Purpose: To examine the differences between single cell and multi cell organisms in terms of Animal and Plant cells. Question: What are the differences between multi and single celled plant and animal organisms? Prediction: Spirogyra Cell: The parts of the spirogyra cell that will be visible under the microscope will be; cell wall‚ cell membrane‚ nucleus‚ chloroplasts‚ vacuole and cytoplasm. Banana Cell: The parts of the banana cell that will be visible

Plant Cell Plant cells are eukaryotic cells or cells with membrane bound nucleus. Generally‚ plant cells are larger than animal cells and are mostly similar in size and are rectangular or cube shaped. Plant cells are similar to animal cells in being eukaryotic and they have similar cell organelles. What is a Plant Cell? Back to Top Plant cells are eukaryotic cells i.e.‚ the DNA in a plant cell is enclosed within the nucleus. The most important distinctive structure of plant cell is the presence

between the structure and function of four specialised human cells. The human body is made up of trillions of different cells; all play a huge role in the running and function of the body. They are the foundation of all living things. Each different cell has its own exclusive job. Without cells the human body would simply fail. All cells contain organelles which are the structures of the cells itself‚ organelles have individual functions. This essay will investigate the structure and function of four

GS104 Lab Report Experiment # 2 Data Collection David Case: January 23‚ 2015 Experiment #2 Data Collection Objectives: Exercise 1: Formulating a Hypothesis about pitching speed. To form a hypothesis for the pitching velocity of a ball. Use a spreadsheet and math to calculate the actual velocity and determine the accuracy of the hypothesis. I will also roll a large ball to measure its velocity and graph its horizontal motion. Materials: Volley

The cell membrane is made up of fats‚ proteins‚ lipids‚ and carbohydrates‚ and is a permeable structure. However‚ this permeation is very discerning because it only lets certain things pass through it. The cell membrane has a layer of phospholipids with hydrophobic ends and hydrophilic tops. The “tails” are made out of phosphate‚ while the “heads” are made up of two strings of fatty acids. There are two layers of these phospholipids‚ called the “bilayer”‚ and the tips of each phospholipid are facing

Lab 2: Protiens and Starches Purpose: An introduction to testing procedures for two large‚ organic molecules: proteins and starches. Hypothesis: In the test for protiens the water‚ being that it is inorganic will not test positive for protiens; it will serve as the negative control. The milk and 50% egg solution should test positive for protien as they are subsatnce derived from animals which contain protiens in order to carry the functions of life. The sucrose will test negative due
