Plant cells are surrounded by:

64% Answer Correctly

	neither a cell membrane nor a cell wall
	only a cell wall
	only a cell membrane
	a cell membrane and a cell wall

Solution

Animal cells are surrounded by a semipermeable membrane which allows for the transfer of water and oxygen to and from the cell. In plant cells, the cell membrane is surrounded by a somewhat rigid cell wall which provides the cell structure and support.

Cellular fermentation takes place:

50% Answer Correctly

	in the presence of oxygen
	anaerobically
	aerobically
	in plant cells

Solution

If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.
