Ou are told that the cells on a microscope slide are plant, animal, or bacterial. You look at them through a microscope and see
cell walls and membrane-bound organelles. You conclude correctly that the cells a) are bacterial cells.
b) are animal cells.
c) are plant cells.
d) could be either plant or bacterial cells.
The cells cannot be animal cells, because they have not wall (this kind of cells has only plasma membrane). In addition, eukaryotic cells have membrane-bound organelles (which are surrounded by a phospholipids membrane, such as endoplasmatic reticulum, Golgi apparatus, lysosomes, etc.), whereas prokaryotic cells lack them. Since plant cells are eukaryotic and bacterial cells are prokaryotic, the cells you are looking are plant cells.
D surface tension because, adhesion is sticking, b makes no sense for this question, and heat has nothing to do with it either, because it distributes it's weight throughout its legs so it doesn't sink (it doesn't weigh much so this works.)
