Chapter 4 Review

1. During the process of diffusion,

• a cell surrounds and absorbs large particles.
• particles move from areas of lower concentration to higher concentration.
• a cell surrounds and gets rid of large particles.
• particles move from areas of higher concentration to lower concentration.

2. Cellular respiration is the process by which

• plant cells create glucose
• cells grow and reproduce
• cells use oxygen to produce energy from food
• cells breakdown food without using oxygen

3. Fermentation in muscle cells produces

• glucose
• lactic acid
• water
• bacteria

4. Photosynthesis allows

• an animal cell to get energy from food
• a cell to produce energy without oxygen
• a plant to produce food (glucose)
• a plant leaf to turn green

5. Cells need to produce new cells in order to

• create new chromosomes
• replace cells that have died
• obtain energy from sunlight
• release energy from food

6. Organelles and chromosomes are copied during

• the first stage of the eukaryotic cell cycle
• the second stage of the eukaryotic cell cycle
• the third stage of the eukaryotic cell cycle
• cytokinesis

7. What must organisms be able to obtain in order to survive?

• energy and heat
• DNA and water
• heat and cold
• energy and raw materials

8. When particles travel from an area of high concentration to an area of low concentration, it is called

• endocytosis
• active transport
• exocytosis
• diffusion

9. Osmosis is important to cells because

• cells contain fluids that are mostly water
• cells are filled with fluids that are mostly sugar
• cells need to be kept cool
• cells need food

10. Passive transport occurs when small particles move from

• outside a cell to inside a cell
• areas of lower concentration to areas of higher concentration
• areas of higer concentration to areas of lower concentration
• inside a cell to outside a cell
