Question

Start another infusion, and expose it to a light courser. This will encourage photosynthetic promises to grow. Add a small amount of the original water to compensate for evaporation. Record your observations in the space provided. Maintain your infusion for several weeks of longer. Keep records regarding populations of protests. Remember to add a small amount of the original water to compensate for evaporation. In the infusion, is there a change in the number and species of organisms? You instructor will provide information about the proper cleanup and disposal of the material used in this activity. Did you observe protists in the water? If so, were they plentiful? Describe the movements of the portraitists. What is the function of a hay infusion? Describe the density of roosts living in the hay infusion. Describe several specimens living in the hay infusion.

Explanation / Answer

1) Protists in water: When you look at fresh water with a microscope you will likely see a variety of tiny living things over 50,000 different species of protozoans.

2) Movement of protists: protists Move using flagella, which are long and threadlike appendages that look like long whips and help organisms move steadily through currents and waves. Pseudopodia is the third type of protist locomotion. This movement involves a temporary projection of cytoplasm through certain cells, such as phagocytes.

3) Hay fusion: A hay infusion is a culture made from water collected from a pond, lake, stream, or puddle. It is an  excellent way to provide microbes at a high density during any time of the year. This process allows you to follow the development of microbes as they become visible over time.

4) Density of the protists in the living Hay fusion:

Procedure

Centrifugation

Place medium with the protists into the appropriate centrifugation tube.

Centrifuge the tubes for 2 minutes at appropriate rpm / g.

Quickly remove the supernatant.

Re-suspend protist cells in the remainder of medium or some replacement liquid depending on the goal.

Quickly proceed with the processing of the cultures, given that a small medium volume with high individual numbers will quickly deplete the remaining oxygen.

5) Several specimen living in the hay fusion: cysts, oocysts, and helminth eggs and larvae Scientists estimate that there are over 50,000 different species of protozoans. Even at that, there are many new protists yet to be found as new species are identified regularly.

A hay infusion is a great way to produce a variety of microbes during any time of the year. The sugars in the dried grass provide food for the bacteria and other microbes. The bacteria serve as food for the protozoa. If the bacteria grow quickly, the protozoa will also grow quickly
