Biology lab test 4,5,6 Questions and
answers
4) Contrast the location of DNA in a eukaryotic cell with that of a prokaryotic cell.
DNA is located in the nucleus of a eukaryotic cell and in a nucleoid of a prokaryotic cell.
We have an expert-written solution to this problem!
What characteristics do all eukaryotic cells have in common?
The presence of a nucleus and membrane-bounded organelles.
Why would you predict that an animal cell, but not a plant cell, might burst when placed in a
hypotonic solution?
Animal cells do not have cell walls. The cell wall of plant cells keeps them from bursting.
Which of the cellular organelles would be included in a category called:
a. Membranous canals and vacuoles
b. Energy related organelles
a. Endoplasmic reticulum, Golgi apparatus, vesicles, vacuoles, lysosomes, peroxisomes
b. Mitochondria and chloroplasts
How do you distinguish between rough endoplasmic reticulum and smooth endoplasmic
reticulum?
a. Structure
b. Function
a. Rough ER has ribosomes; Smooth ER doesn't
b. Rough ER is the site of protein synthesis; Smooth ER has various functions
We have an expert-written solution to this problem!
If a dialysis bag filled with water is placed in a molasses solution, what do you predict will
happen to the weight of the bag over time? Why?
The bag will lose weight, water would diffuse out of the bag and enter the molasses solution.

How does plant cell structure aid the ability of plants to stand upright?
Strong cell walls and water-filled vacuoles that maintain turgor pressure help plants to stand
upright.
