Unit2 Prokaryotic and Eukaryotic Cells Ribosomes What is represented by the small dots found in each of the bacteria cells? Cell Wall What is the name of the outermost layer that forms a boundary around the outside of each cell? Free - Floating DNA How is the DNA described and what does this mean? Cytoplasm All the internal structures are suspended (floating) in what substance? Flagellum a. What is this structure called? To move the cell around b. What might be the purpose of this structure? Those other two cells are not able to move. c. Based on your answer to the previous question, what might you infer about the absence of this structure in the other two bacteria cells? Plant cell has cell wa Plant cell has a large vacuole Plant cell has a chloroplast Looking at Model 2, list at least three structural differences (other than shape) between an animal and a plant cell. The DNA is inside the nucleus Where do you find the DNA in each cell in Model 2? Yes! = Eukaryotic Do both cells in Model 2 have a nucleus? In plant cell it is the cell wall and cell membrane In animal cell it is just the cell membrone List the structure (s) that from the boundary between the inside and the outside of each cell in Model 2. In a plant the cell wall is the out most boundary What is different about the outermost boundary in a plant cell compared to an animal cell? Prokaryotc = Before Nucleus The chart in Model 3 to determine the meaning of the word prokaryote. Model 2 is more complex: 1. Has a nucleus to hold DNA 2. Has lots of specialized organclles 3. These cells conse specialized multicelllar Decide as a group whether the cells in Model 1 or 2 are more complex and list at least three supporting reasons for your choice. Eukaryyote = True Nucleus What does the word eukaryote mean? Cell wall, cell membrane, Ribosomes, bacteria, cytoplasm, DNA By comparing Model 1 and Model 2 , what structures are the same --- Plant and Animal in both prokaryotic and eukaryote cells? Prokaryotic cells are simple cells like bouteria they lack a nucleus and membrane wound organelles As a group, write a definition for a prokaryotic cell. Nucleus ER Mitochondria Golgi Apparatus Vocuoles Lysosomes Chloroplasts What differences are there between a prokaryotic and eukaryotic cell? Eukaryotic cells are complex cells like plant and animal they have a true nucleus and many organelles As group, write a definition for a eukaryotic cell. some have and some do not The words prokaryotic and eukaryotic must be used: All cells are not the same becuase........ 1/1
