Purpose:
To observe different species of living protists in pond water under the microscope. Taking note of their size, movements, and characteristics to classify the different types of protists from applying previous knowledge of protists.
Materials:
The materials in this lab that will be needed are a microscope, slide, coverslips, a pipette, and a dish of pond water.
Procedure:
Prepare a slide by using the pipette to apply two drops of pond water on a slide and properly place a coverslip.
Place the prepared slide under the microscope to view and decide the most suitable objective lens to view the protist under, starting with low power.
Move the slide around to find the protists present in the pond water and if needed, put the slide …show more content…
The oxytricha lives in freshwater and saltwater, in lakes or streams. Oxytricha have hairlike projections, cilia, that helps them for feeding and movement. The beating of the cilia helps oxytricha by propelling them forward rapidly through the water. From the cilia, oxytricha use them to sweep food particles into its gullet, indicating that they are heterotrophic. The size that oxytricha ranges from are 40 to 240 micrometres. Oxytricha possesses two nuclei, a macronucleus and a micronucleus, the macronucleus containing most of the genes that the cell would use daily and the micronucleus serves at the “back up” copy of the genes. The oxytricha can reproduce both asexually and sexually, by mitosis through binary fission, asexually, and sexually by conjugation. The oxytricha was easily identified as a ciliate from the cilia that surrounded the body that helped it move quickly and smoothly through the water. The body of the oxytricha was filled with spots and contained two outlines of a circle which were the macronucleus and micronucleus. The characteristics of the oxytricha were expected from observation since it is similar to other species of the phylum and other
