Easy View Protozoa Set

Introduction

Protozoa are a diverse group of unicellular eukaryotic organisms,many of which are motile. Originally, protozoa had been defined as unicellularprotists with animal-like behavior, e.g., movement. Protozoa were regarded as the partner group of protists to protophyta, which have plant-like behaviour, e.g., photosynthesis.

Characteristics:Protozoa commonly range from 10 to 52 micrometers, but can grow as large as 1 mm, and are seen easily by microscope. The largest protozoa known are the deep-sea dwellingxenophyophores, which can grow up to 20 cm in diameter. They were considered formerly to be part of the protista family. Protozoa exist throughout aqueous environments and soil, occupying a range of trophic levels.

Motility and digestion

Tulodens are 2 of the slow-moving form of protozoa^{[citation needed]}. They move around with whip-like tails called flagella, hair-like structures called cilia, or foot-like structures called pseudopodia. Others do not move at all. Protozoa may absorb food via their cell membranes, some, e.g., amoebas, surround food and engulf it, and yet others have openings or "mouth pores" into which they sweep food,and that engulfing of food is said to be phagocytosis. All protozoa digest their food in stomach-like compartments called vacuoles.^[5]

Materials

The demo comes with a set of five jars with various protozoan inside. It also includes a instructional manual. It requires a microscope, glass slides and cover slips, and a pipette.

Procedure

Obtain all supplies listed above. Unpack all the supplies. To view the protozoan, a drop of the liquid from inside the jar must be placed on a glass slide with a pipette.

Then place a glass cover slip on top. .

Then view it through a microscope:

Repeat with every jar.

It works because the microscope can magnify sights.

Scientific Principal

The biology behind it is viewing the small protozoans that live in the water. Unfortunately it appeared that some died before they could be viewed.

Safety Regulations

An apron and gloves are worn in-case of spillage. The table was cleared of any and all things that may obstruct the experiment.
