11. What is the maximum magnification of most classroom compound light microscopes?
100x
500x
1,000x
5,000x

12. Shannon is making a Venn diagram to organize the characteristics of cell walls and cell membranes. Which pair of characteristics both belong in the two areas of the Venn diagram that do not intersect?

helps with communication; contains mostly cellulose
contains mostly cellulose; forms the outer layer of animal cells
is found in plant cells; is found in animal cells
is semipermeable; found in animal cells

13. Two cells in the same organism differ only in the number of chloroplasts they contain. The first cell has multiple chloroplasts, and the second cell has very few. What would most likely characterize these cells?
There would be no difference between the functioning of the cells because the chloroplasts are not essential cell structures.
The second cell would become larger because it would have fewer chloroplasts regulating its size and shape.
The second cell would shrink because it would not be able to store water and maintain cell shape.
The second cell would not be able to produce as much food because it could not capture very much sunlight.

vacuoles
mitochondria
chloroplasts
centrioles

Answer 4

9. phagocytosis

Answer 5

It seems like you're referencing question 9 from the previous set. If you're looking for an explanation regarding "phagocytosis" in the context of the endosymbiotic theory, let's clarify that.

Endosymbiotic Theory Context:

The endosymbiotic theory describes how eukaryotic cells may have evolved from prokaryotic cells through a symbiotic relationship. Specifically, it states that some organelles (like mitochondria and chloroplasts) were once independent prokaryotic organisms that were engulfed by ancestral eukaryotic cells.

Phagocytosis:

Phagocytosis is a specific form of endocytosis where a cell engulfs solid particles or smaller cells, which could include bacteria. In this context, phagocytosis itself is not the process that led to the evolution of mitochondria and chloroplasts, but it is related to the general mechanisms of cellular uptake and could be part of how early ancestral cells incorporated other cells into their structures.

In the context of the original question asking what process was involved in the evolution of mitochondria and chloroplasts according to the endosymbiotic theory, the most appropriate answer is still endosymbiosis, as it encompasses the broader idea of a symbiotic relationship leading to permanent incorporation of one organism into another.
