Please HELP ! :( 3.4.4 Why are cells so small?
All the question are down below Please answer them right

1. Write a brief summary of the main steps you took in the procedure. Be sure to describe any adjustments you made to the procedure and why you made them. (3 points)

2. What is the step or steps that make or break the results in this procedure? Consider how the sizes and shapes of the filter paper model cells affect the results. (3 points)

3. What did this lab teach you about how the size and shape of a cell affects the rate of diffusion of a substance into that cell? (3 points)

4. A living cell is not a simple geometric shape, like a sphere or a cube. What sort of weird cell shape might increase the ratio of surface area to volume? Would you be able to test this more complex shape in a experiment similar to this one? (3 points)

5. What other models could you make to represent a living cell? What sort of questions about a living cell could you investigate using you model? (3 points)

What is the relation ship between structure and function in an organism

Where can you find prokaryotic and eukaryotic cells?

Mouse liver cells were homogenized and the homogenate subjected to equilibrium density-gradient centrifugation with sucrose gradients. fractions obtained from these gradients were assayed for marker molecules (i.e., molecules that are limited to specific organelles). the results of these assays are shown in the figure. the marker molecules have the following functions: cytochrome oxidase is an enzyme involved in the process by which atp is formed in the complete aerobic degradation of glucose or fatty acids; ribosomal rna forms part of the protein-synthesizing ribosomes; catalase catalyzes decomposition of hydrogen peroxide; acid phosphatase hydrolysis monophosphoric esters at acid ph; cytidylyltransferase is involved in phospholipid biosynthesis; and amino acid permease aids in transport of amino acids across membranes. a) name the marker molecule and give the number of the fraction that is most enriched for each of the following cell components: lysosomes; peroxisomes; mitochondria; plasma membrane; rough endoplasmic reticulum; smooth endoplasmic reticulum.
