If your observations had not been restricted to the area of the root tip that is actively dividing, how would your results have been different?Cells are in interphase 90% of the time, and, since most of the creation of plant cells occurs in the root tips, you would witness mostly interphase. 2.Based on the data in Table 3.1, what can you infer about the relative length of time an onion root tip cell spends in each stage of cell division?Most of a cells life cycle is spent in interphase. Metaphase is the longest stage of mitosis, and anaphase is the shortest.1.List three major differences between the events of mitosis and meiosis.Meiosis has four nuclear divisions, whereas, mitosis only has one; meiosis creates four haploid cells, whereas mitosis creates two diploid cells; and meiosis is the only one taking part in crossing over.2.Compare mitosis and meiosis with respect to each of the following in Table 3.2:Table 3.2Mitosis MeiosisChromosome Number of Parent Cells2n2nNumber of DNA Replications11Number of Divisions12Number of Daughter Cells Produced24Chromosome Number of Daughter CellsDiploid (2n)Haploid (n)Purpose/FunctionRepair and GrowthGamete and Spore

Answer:
1st factor is:Cornified layers:loss of water in the cell in the layer of dying cells
2nd factor is infusion of keratin its a dense protein that hardens the skin cell to aid in producing a barrier against the outside world
I believe it is carbohydrates.
Your answer is B Plant cells have cell walls instead of cell membranes because plants have cell walls to support, protect, and carry water through out the cell animals cells don't have that. Its also not A because they both have vacuoles its not C because they both have choralpast.
Your answer is B.
BTW if not B its all of the above.
