Q1: A) Lawn Care’s current strategic mission is to provide the highest-quality grass seed and fertilizer in the industry. Their competitive priorities are cost‚ quality‚ and flexibility. Currently‚ they charge a lower price for their products than competitors because they are not bundling service with products. However‚ they offer high-quality products that give them an advantage over competitors. Also‚ they strive to offer “the right products to the right customer at the right time‚” which shows

Cell Biology (CP8121) Experiment 2: Observing Mitosis and Meiosis on cell specimens (Formal report) Name: Wong Chung An Class: DMLS/FT/1B/02 Admin number: P1138687 Summary This experiment aims to observe mitosis and meiosis on cell specimens. It involves the modelling of the stages of meiosis and also the staining procedures to identify mitosis in onion root tip. There are two parts to the procedure of the experiment whereby the first is staining and observing mitosis in onion root tips and the

plasmoylsis and turgor in plant cells Investigation * Get a single layer of plant cells. If you are using red onion‚ cut a 1 cm square from a fleshy piece of onion and then peel off a single layer of the red cells. If you are using rhubarb‚ peel a piece from the epidermis. If you are using toadflax peel a piece of the lower epidermis of a leaf. * Place the strip on a slide and cover it with a drop or two of distilled water. Add a cover slip. * Look at the cells through a microscope. Start

Some of you have been asking for clarification regarding your optional use of the MSAF‚ the student self-reporting absence form. As you may know‚ this is allowance that you are permitted to use once per term to address temporary illnesses and deadline pressures. The allowance provided is generally five days‚ but faculty are asked to specify how the MSAF is to be applied in their particular course. Here are my guidelines: For all other more serious illnesses and absences‚ you would follow the

Cells are the basic functional units of all organisms. Cells are the smallest unit of life and are often called the "building blocks of life". The distinction between prokaryotes and eukaryotes is considered to be the most important variation among groups of organisms. Eukaryotic cells contain membrane-bound organelles‚ such as the nucleus‚ while prokaryotic cells do not. The differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the

Period: H Plants and Animal Cells Abstract: In this lab‚ you will find out how plant and animal cells are alike and how they are different. The onion elodea cells were both plants‚ so they had a cell wall. The cheek cells were animal cells‚ so they did not have a cell wall. Eukaryotic cells contain structures called organelles that carry out life processes. Eukaryotic cells can be classified by the types of organelles they contain. In plant and animal cells‚ similarities and differences exist because of varied life functions

Differentiating Between Prokaryotic and Eukaryotic Cells‚ Distinguish Among Plant‚ Animal‚ and Protist Cells‚ and Identifying the Organelles that are Evident in Them Introduction There are two different types of cells‚ prokaryotes and eukaryotes. Prokaryotes‚ such as bacteria‚ lack a nuclear membrane and other membrane bound organelles. Their genetic material consists of a single molecule of singular DNA. Eukaryotes‚ such as plant and animal cells‚ have a nuclear membrane and other membrane bound

Plasmolysis in Rhubarb Epidermis Cells Aim: To see if rhubarb changes when it is placed in solutions of different concentrations. Introduction: "Plasmolysis in Rhubarb Epidermis Cells" is an experiment to see whether or not rhubarb changed its cell structure when placed within different types or solutions. "A single layer of plant cell is placed on a micrscope slide and either distilled water or 5% NaCl solution is added to the cells. Osmosis will occur resulting in either turgid cells or
