- Each compartment of the endomembrane system of a cell is connected to the plasma membrane. Create a simple diagram of a cell including the RER, Golgi apparatus, vesicle, and the plasma membrane. Starting with the RER, use two different colors to represent the inner and outer halves of the bilayer for each of these membranes. What do you observe?The physical characteristics of a cell influence how it functions. For example, the surface area and volume of a cell affect how efficiently waste is removed from the cell via diffusion. The table below shows data for four different cuboidal cells. Cuboidal cell Side length (um) Cell A 1 Cell B Cell C Cell D Surface area of a cube: A = 6s2 Volume of a cube: V = s3 Using the information from the table, what is the surface-area-to-volume ratio for the cuboidal cell that removes waste via diffusion most efficiently? -1 um 2. 4.Below are three statements - two of which are truths and one is a lie. Which of the following statements is a lie? Select one: a. The main component of the plasma membrane is the phospholipid bilayer which is composed of hydrophilic heads and hydrophobic tails. b. Integral proteins also referred to as cell-specific proteins function as enzymes, as structural attachments to the fibers of the cytoskeleton, or as cell-recognition sites. c. The collective carbohydrates found on the cell's exterior surface is called glycocalyx which means "sugar coating".
- Select the statement regarding the plasma membrane that is FALSE (if any). Select one: O a. All living organisms have cells with plasma membranes O b. The phospholipid bilayer has a hydrophobic region and a hydrophilic region. c. Because of the plasma membrane's selectivity permeability, a cell's interior is chemically very different from the surroundings outside. O d. None of the above (meaning all statements are true).In biology, the phrase "form fits function" is often used to describe the relationship between a particular structure and the job that structure has to do. This is easily seen in the structure and functions of the organelles and other components seen in the bacterial, plant, or animal cell. In 3 or 4 sentences, describe the structure and function of two different organelles or cellular components. In your answer, address the following for two separate organelles: Briefly describe the structure of two different organelles, including the name of each organelle. Describe how each of the two particular structures helps that organelle to do its job. Be specific!What is the visible structure at the edge of the type of cell represented by "B"? A. В. С.
