- Animal cell, Plant cell or Both? 1) Chloroplast 2) Cell Membrane 3) Cell Wall 4) CytoskA student develops four models for the composition of a eukaryotic cell. The weight of the cell is broken down as the percentage of the total cell weight for each of the components. Which model indicates the CORRECT percentage values for the components of an actual cell and why? A Model A because this model shows that nucleic acids are the most abundant macromolecule, and nucleic acids are the most important macromolecule because they contain genetic information. B Model B because this model shows that proteins are the most abundant macromolecule, and proteins are the most important macromolecule because they are the most diverse and are involved in many cell structures and functions. C Model C because this model shows that phospholipids are the most abundant macromolecule, and phospholipids are the most important macromolecule because they are the main component of the cell membrane. D Model D because this model shows that nucleic acids are the least abundant…Where does RNA translation into amino acids takes place? 1. Cytoplasm 2. Endoplasmic reticulum 3. Nucleus 4. Vacuoles 5.

- Explain Nontypical Cell Walls with an example.You are looking at the inside of a cell . How can you tell the cell is animal, bacterial or a plant cell ?Single choice. A. animal cell - nucleus ,no cell wall; bacteria cell -no nucleus ; plant cell- nucleus, cell wall and chloroplast B. animal cell - no nucleus, no cell wall ; plant cell - nucleus , no cell wall C. bacteria cell- nucleus ,no cell wall ; animal cell - nucleus ,cell wallMake a T-chart using the following paragraph: All living organisms will fit into two different categories; prokaryotes and eukaryotes. Eukaryotes, the more complex cells, are made up of one or many cells. These eukaryotic cells have a nucleus and membrane-bound organelles. Prokaryotes, the simpler cells, do not have a nucleus or membrane-bound organelles. Almost all the prokaryote organisms are single-celled. It is important to know that the only way we can see these organisms is by using a microscope.
