Cell Review for Test
- What are the 3 parts of the cell theory? A) Cells are the basic unit of life. B) All cells are produced from other cells. C) All living things are composed of cells.
- Remember Francisco Redi’s experiment with meat in the jars, one group was left open and the other jars were covered with a cloth. What part of the cell theory does this experiment support? All cells come from pre-existing cells.
- What happens during cellular respiration? Glucose is broken down releasing energy
- During the yeast lab what was happening when we added the yeast, sugar and water together?
Cellular respiration. Sugar was being digested and used as energy.
- What organelles do plant cells have that animal cells do not? Chloroplasts and cell wall
- Cells in many-celled organisms are often quite different from one another. True or False?
- Why are cells and living organisms similar? a) They both have to eliminate waste. b) They both reproduce.c) They both process nutrients.
- 8. What is the function of the cell membrane? To control what enters and leaves the cell.
9. What is the function of the cell wall? To protect and support the cell.
10. What organelles produce proteins in the cell? ribosomes
11. Where are the chromosomes found and what do they contain? Found in the nucleus and contain DNA- instructions that direct the functions of a cell.
12. What organelles produce most of the energy needed by the cell? mitochondria
13. Which organelles release chemicals that break down large food particles into smaller ones? Lysosomes.
14. Which body system breaks down the food into a usable form like the organelle in question #13? Digestive system
15. Which body system filters the blood to remove waste products in the body? Excretory
16. Which cell organelle performs a similar function as the body system in question #15? vacuole
17. Which cell organelle captures energy from sunlight during photosynthesis? Chlorophyll
18. What happens during photosynthesis? The cell uses the energy in sunlight to make the food.
19. What are the products of photosynthesis? Oxygen and sugars (Remember “GO”…Glucose and Oxygen)
20. What product of photosynthesis do most living things need to survive? oxygen
21. Remember the radish seed lab. Why do plant stems tend to grow upward and the roots tend to grow downward? Plant stems grow upward because of phototropism. Roots tend to grow downward because ofgravitropism.
22. Which one supports cell theory?
a. Because earthworms breathe through their skin, they come up from soil after a heavy rain and rest on the surface.
b. Frogs tunnel into mud during hot or dry periods and then emerge from the mud after spring floods.
c. Brine shrimp hatch from eggs in a shallow pond.
d. After metamorphosis, Monarch caterpillars come out of a cocoon as a butterfly.
