"With the nucleus"

18. Mitochondria produces ribosomes with....

1.-ATP for protein

22. Which pair of structures best shows that plant cells have functions different from animal cells?....

1.-Chloroplasts and cell walls

16. In the human body, the circulatory system transports and delivers substances. Within the cell, which organelle performs a similar function?..

2.-ER

17. Of the following organelles, which group is involved in manufacturing substances needed by the cell?

3.-Ribosomes rough and smooth ER

24. When an animal eats, the food stays in the stomach for a period of time. When a unicellular organism such as Paramecium takes in food, the food is contained in which organelle?

3.-Vacuole

19. The golgi apparatus packages materials into for transport or export?..

3.-Vesicles

23. What structure can be found in all living cells?...

3.-ribosomes

21. A student wrote this description of a cell after looking at it under a microscope. Which type of cell was the student most likely describing?...

4.-Plant cell

20. Lysosomes....

All of the choices are correct

3. Which of these supports the cell theory as it is stated today?

All organisms are composed of more than one cell

9. In the 1660s, Flemish physician Jan van Helmont grew a small willow tree in a pot of soil. He added only water to the pot. At the end of five years, he found that the tree had gained 75 kilograms, but there was very little change in the mass of the soil. Van Helmont concluded that the plant gained weight directly from the water. We now know that this conclusion is only partially correct because, in addition to water, photosynthesis also requires(a gas we exhale...):

Carbon dioxide from the atmosphere

14. Which system in a multicellular organism functions most like the Cytoplasm in a single celled organism?

Circulatory

6. Early elements of the cell theory followed soon after the development of Hooke's light microscope. What does this relationship suggest about the evolution of the cell theory since Hooke?

Improvements in the technology are closely related to changes in the cell theory

5. Which of the following best summarizes why the technological invention of microscopes was important to biology?

It allowed for the development of the cell theory elements

13. Which of these functions most like the "brain" of the cell?

Nucleus

1. Which is not part of the Cell Theory?

Only eukaryotic cells have a nucleus

8. In 1864, Louis Pasteur was asked to investigate diseases afflicting the wine in Arbois, France. He discovered that these diseases were caused by microorganisms that could be killed by heating wine to 55 degrees celsius for a period of time. What this process called today that applies to milk?

Pasteurization

15. Which of the following is a function of the cell membrane?

Regulates the movement of materials into and out of the cell

12. Protein synthesis is accomplished primarily by the interaction of which two cell structures?

Ribosomes and vacuoles

2. The invention of the microscope enabled scientists to observe cells, helping them to:

discover a basic similarity among organism

7. The results of Pasteur's experiment helped Pasteur to:

experiment rejected the theory of spontaneous generation

11. Tiny structures that carry out cell functions are collectively called:

organelles

4. To help patients replenish bodily fluids quickly during an illness, doctors need to understand how cells behave in their environment. Doctors have confidence in what they know about how cells behave because:

the cell theory has been tested, refined, and observed to be true over hundreds of years
