Part B – Short Answer
31. With the support of a diagram, explain OSMOSIS?
 The movement of water that does not require energy across a cell
membrane from an area of higher concentration to an area of lower
concentration
32. What is CYTOKINESIS?
 The stage of the Cell Cycle following mitosis when two daughter cells are
formed
33. Why is there a limit to cell size?
 Cells need a constant supply of nutrients, water and oxygen. As well,
wastes must be removed from the cell. The processes of “entering and
exiting” a cell are (1) osmosis, (2) diffusion and (3) active transport. If a cell
was large, it would require more supplies and removal. The cell would not
operate efficiently.

Cells must communicate internally. The nucleus must efficiently receive
signals from the surrounding environment, and then, quickly communicate
messages to other cell organelles to react to changes in the environment.
34. What are the three primary functions of a cell?
 Grow
 Reproduce
 Repair
35. What is the difference between AEROBIC RESPIRATION and ANAEORBIC
RESPIRATION?
 Aerobic is cellular respiration that uses oxygen
36. Fill in the following table by identifying the cell part that performs the function described

37. What is RESIDUAL VOLUME?
 The one litre of air remaining in the lungs after air is exhaled from the lungs
38. Why do humans need to be eating constantly
 Our cells require a constant supply of nutrients
 Our cells are poor stores of energy
 Our cells are constantly using energy, and it must be replaced
39. Cells need a constant supply of oxygen. Describe the steps that are needed to get the
oxygen from the external environment to (…and into…) the cell.
 Oxygen enters the body via the nose and mouth and travels down the
trachea to the lungs. Oxygen in the lungs diffuses into the circulatory
system, and then, red blood cells of the circulatory system (heart) carry it
to the cells. At the cells, the oxygen diffuses across the cell membrane and
enters the cell
40. Why do you make a wet mount slide?
 To observe live cells
41. What is the product of Mitosis?
 Two identical daughter cells
