A lab experiment on the identification of cellular division in plant and animal cells

Biology G — General Botany Prerequisites: Biology G This course is designed to satisfy the major requirements for an Associate or Baccalaureate degree in the Biological Sciences. Biology G complements Biology G and G as the third of three in a sequence of survey courses. Biology G and Mathematics G or G or G or G or G, or Mathematics Placement Assessment A survey of extant living organisms including physiological and anatomical adaptations of organisms in response to their environment.

This allows students to focus on the process and techniques of investigation and the subsequent reporting. However, in Year 12 students are often given freedom to choose a topic or research question from the work covered over the whole of the course.

These "Open Inquiry" EEIs may provide more ownership, engagement and deeper understanding for the students but do place a bigger demand on resources and laboratory management. However, many teachers have found strategies to manage this should they choose to opt for a Open EEIs.

Examples of Risk Assessment forms can be found in the tasks available on this page. A comprehensive form developed over several years by Urangan SHS can be found here: It is only an example and should not be assumed to necessarily meet the legal and safety obligations of any particular school or situation.

The method of artificial variation: The method of concomitant variation: This is also called a "correlation method".

You can think that nature has manipulated the variables but it is still appropriate to class one as dependent and one as independent. For example, do young leaves have the same density and distribution of stomata as older leaves; or how does temperature IV in a natural environment affect stoma opening DV?

In this second case you do not need you to control the environmental temperature, but you do need to measure the DV at different temperatures. The difficulty with the second approach is the control of other potentially influential variables such as humidity - as you have to take what you get.

However, that does not preclude the variables in relationship being considered the IV and DV or being graphed as such. One way to address the confounding variables eg humidity is to collect data on the other variable as well.

You can run the statistics on each pair separately, but, for students who are not that "stats-savvy" then they could look for interactions between them at a visual level.

Food, as well as meeting the nutritional requirements of humans, will also meet the nutritional needs of a vast range of micro-organisms. These microbes will multiply rapidly in food, given the appropriate conditions such as temperature, pH and moisture.

The flavour, aroma and texture will ultimately be affected. Those most affected by food poisoning are the elderly, the young and immune suppressed individuals. A petri dish culture of the yeastlike organism fungus Candida krusei, after 10 days growth on dextrose agar.

This species is known to be a food spoilage organism.

Steps in Cell Division

Dichloran Rose Bengal Chloramphenicol Agar is a commercially specialist culture medium for viable yeasts and moulds in food products. It incorporates Rose Bengal, which both helps limit colony size and is selective against bacteria.

Effects of different anti microbials on bacterial growth Joseph Lister first introduced aseptic surgery in when he used a spray of carbolic acid phenol C6H5OH as a germicide.

Since then the control of growth by antimicrobial compounds has grown into a multi-billion dollar industry. A good EEI is to assess the effect of a variety of antimicrobial disinfectants on bacterial growth. Our labbies prepare the plates and order in E.

Small paper discs like out of a hole punch are sterilised and then soaked into different anti-microbials. The discs are placed onto the agar plates and then into the incubator for a couple of days. If the anti bacterial is effective there is a clear ring around the disc where the E.

Students have used the width of this ring to indicate effectiveness and to collect quantitative data. The experiment can work quite well; keen students have then researched the active compounds within the antibiotic, how they act upon the bacteria and link to the results observed".

Mitosis & Meiosis | Experiment #3 from Advanced Biology with Vernier

No single disinfectant is ideal. Each has its advantages and disadvantages.The Modeling and Microscopic Observation of Mitosis and Meiosis in Plant and Animal Cells Prelab Assignment however, will consider cell division in eukaryotic organisms only.

Lab 8. Mitosis and Meiosis (revised Fall ) Lab 8 - Biol - Page 2 of 1. INTRODUCTION - OVERVIEW - Biology as a science deals with the origin, history, process, and physical characteristics, of plants and animals: it includes botany, and zoology.

A study of biology includes the study of the chemical basis of living organisms, rutadeltambor.com related sciences include microbiology and organic chemistry. Large Vacuole: While animal cells may have many tiny vacuoles, a plant cell usually has a single large vacuole, which serves as a storage tank for food, water, waste products, and other materials.

The vacuole has an important structural function, as well. acquired trait: A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation (for example, the large.

The general Cell and Plant biology session invites posters on all the aspects of plant and cell biology that are not catered for in the specific section sessions. As such, the session is an important element of the scientific programme, with high-quality presentations on a wide spectrum of subjects.

The purpose of this laboratory experiment was to identify in what stage of mitosis viewed all cells come from other cells. New cells are formed during cell division, which involves both the replication of the cell’s nucleus and division of the whitefish blastula is an animal cell while the onion root tip is a plant cell.
