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
