1) If you were shown an electron micrograph of a section of a cell and were asked to identify the cell as plant or animal, one thing you might do is

a) look for plastids or ribosomes.

b) look for plastids or Golgi complex.

c) look for plastids or a large vacuole.

d) look for plastids or mitochondria.

2) A slice of raw apple placed in a concentrated sugar solution will

a) become turgid as water is drawn into its cells.

b) become turgid as water is drawn out of its cells.

c) become flaccid as water is drawn into its cells.

d) become flaccid as water is drawn out of its cells.

Solution

1) If you were shown an electron micrograph of a section of a cell and were asked to identify the cell as plant or animal, one thing you might do is: c) look for plastids or a large vacuole.

Reason:Plant cell contains palstid /cholorplast and large vacuoles that is missing in animal cell.

2) A slice of raw apple placed in a concentrated sugar solution will :d) become flaccid as water is drawn out of its cells.

Reason:Osmosis will result in outward movement of water from apple cells to the sugar solution and thus become flaccid.
