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

Prokaryote cell suspension Methodology Part 1 : Onion cell wet mount 1. A translucent piece of tissue from onion was peeled. 2. The piece of onion was placed on a glass slide and a drop or two of the Methylene blue solution was added. 3. The onion cell was observed under low‚ medium and high power. A drawing of one cell was made‚ using a pencil and all of its part are labelled. Part 2 : Cheek cell wet mount 1. The inside lining of your cheek with a toothpick was scraped gently

spatial exclusion. These urban dynamics are dominant in Pyrmont Ultimo and have contributed to the changing morphology of that area. Pyrmont-Ultimo has undergone distinctive changes between the 18th century and 21st century. It has been transformed from the former warehousing and industrial suburb into a thriving residential‚ commercial and business precinct. The original morphology of Pyrmont-Ultimo allowed the area to become very popular and attractive. The close proximity to Sydney city

Bacteria and Archaea. 2. What types of organisms are Eukaryotes? Eukaryotes can be single-celled or multi-celled‚ and their DNA is contained in a nucleus and has membrane bounded organelles. There are four kingdoms of Eukaryotes‚ Protista‚ Animalia‚ Fungi and Plantae. CELLS ALIVE!

frequently in water‚ especially in plankton.Phytoplankton is the population of free‐floating microorganisms composed primarily of unicellular algae. In addition‚ algae may occur in moist soil or on the surface of moist rocks and wood. Algae live with fungi in lichens. According to the Whittaker scheme‚ algae are classified in seven divisions‚ of which five are considered to be in the Protista kingdom and two in the Plantae kingdom. The cell of an alga has eukaryotic properties‚ and some species have

Whilst most assemblages will contain a majority of broken shells each one is unlikely to hold over 30 types of snail species so identification of a small number of these can soon lead to a general pattern of the number and types that are within the sample being studied. Differences in the axis‚ apex‚ whorl‚ spire‚ columella‚ mouth‚ lip and the overall shape and colour lead to the morphology of a preserved snail
