1. Examine several drops of the culture of pond water that you collected, or examine the unknown gulture provided by the instructor. Record in Table 2.I the characteristics of at least four different organisms 2. 3. Determine if a well-defined nucleus and organelles are present (eu karyote) TABLE 2.1 Characteristics of Organisms Found in Pond Water Eukaryote Cellular Organization(yes or no) Cell Wall Chloroplasts Unknown Means of Locomotion Paol 4 Volvo REVIEWING YOUR KNOWLEDGE 1 Describe at least two types of materials or observations that would neces- nnic microscope.

Explanation / Answer

Ans- amoeba- locomotion occurred by the pseudoppdia also false feet - cell wall absent- chloroplast absent- unicellular organism - eukaryotes because ameba cell has a nucleus and membrane-bound organelles.

Protococcus- locomotion absent-cell wall present-chloroplast present-unicellular fresh water green algae- unicellular

scenedesmus- The spines are flotation devices -cell wall and chloroplast both are present-grows as single cell possessing 4 spines but to protifrom predators they forms longer chains - eukaryotes

Volvox-locomotion occurred by flagella -cell wall and chloroplasts both are present- unicellular-eukaryotes

Eudorina-flagella-both organs are present -multicellular - eukaryotes
