Lab Report Comparing Animal and Plant Cells The cell is the fundamental structural unit of all living organisms. Cells help carry out the functions of life and together support the organism to function as a whole. Cells are divided into two main categories of eukaryotes and prokaryotes. Animal cells and plant cells fall into the division of eukaryote cells that have both a nucleus and organelles. In this lab‚ animal and plant cells will be compared through a microscope to identify differences

Enzymes play a vital role in helping our body function. They act as biological catalysts and help speed up reactions that would otherwise take long periods of time to naturally occur. Enzymes help lower the activation energy required for the reactants to reach the transitional state from which then they can form products. However‚ enzymes do not change the free energy of the reaction. Enzyme’s ability to catalyze reactions comes from the shape of the active site on the enzyme. Enzymes are hyper-specific

Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that

Plant-Animal Coevolution Evolution Charles Darwin gave what could be described as a loose definition of evolution when he wrote “descent with modification” (Darwin‚ 1859). Evolution is defined more specifically as a change in the genetic composition of a population‚ from generation to generation (Reece et al.‚ 2011). In this investigation into coevolution‚ in particular plant-animal coevolution‚ the adaptations and reasons for these adaptations in a specific example of plant-animal coevolution will

Title: To examine an animal and cheek cell using a compound microscope Date: 25th September 2012 Lab Partner: xxxxxxxxxxxxx Objective: The main aim of this experiment was to prepare a wet mount of human cheek cells and a wet mount of plant cells and examine them both under a compound microscope. Introduction: Cells are the basic units of life which make up every structure in the human body. They are the smallest units which are living. All cells contain different organelles which

Scientific Name of Plants Ornamental Perennials The following is a list of the common plant names cross referenced to the scientific name of plants. The list represents some of the most popular varieties of perennial plants. The scientific names of plants is based on taxonomy‚ the science of plant classification. Each name has two parts‚ the genus and the specie. This is referred to as the binomial (two names)system founded by Linnaeus‚ a Swedish botanist. Some species will have a third name‚ called

131 Lab #2 Drawings of Animal and Plant Cells Instructions: 1. Set up light microscope for use. Handle with care. 2. Obtain a slide of animal cells and observe first under low-power (4X)‚ then under medium power (10X)‚ then finally switch to high-power (40X). 3. Make careful observations of the structure of the cells. 4. Draw what you see under high power on a sheet of paper. Place your drawing in a circle measuring 10-15 cm. Use only pencil‚ draw neat lines‚ do not shade. The title of the

Lab Report: Enzyme Lab Your Name: Samantha Butcher Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? It is going to explain how a liver’s enzymes break down substances that could be harmful.| Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. Give your reasons and outline any assumptions that lead

Introduction Enzymes are proteins produced by living organisms to speed up the rate in which chemical reactions occur. This process can happen fast‚ slowly‚ or stop the chemical reaction all together depending on the temperature‚ pH and concentration. Catalase is one of the most common enzymes. It is found in living organisms and is used to break down hydrogen peroxide. This must happen because hydrogen peroxide is considered toxic to cells in the body. However‚ when catalase is used it breaks it down
