|
Prokaryotic cells
|
|
|
2 .What do Prokaryotic cells lack ?
|
internal membrane-bound structures
|
|
|
3 Where are Eukaryotic cells present?
|
in all living things except bacteria.
|
|
|
4. Do Eukaryotic cells have internal membrane-bound structures
|
4. yes, they have many kinds
|
|
|
5. What is a Neucleus?
|
5. The structure in which the cell's hereditary material (DNA) is located.
|
|
|
6. What does the word prokaryotic mean?
|
Prokaryotic means "without nucleus."
|
|
|
7. What is the difference been a prokaryotic cell and an eukaryotic cell?
|
A prokaryotic cell has no nucleus. An eukaryotic cell contains both a nucleus and many organelles.

A prokaryotic cell has no nucleus. An eukaryotic cell contains both a nucleus and many organelles.
|
|
|
10. Which cells ar larger? Prokaryotic or eukaryotic?
|
10. Eukaryotic cells are, on average, about 10 times larger than prokaryotic cells.
|
|
|
11. What are the specialized internal structures of eukaryotic cells called?
|
11, The specialized internal structures of eukaryotic cells are called organelles.
|
|
|
12. What lies just outside the cell membrane of most bacteria and all plants?
|
12. The cell wall lies just outside the cell membrane. It gives the cell its shape and provides protection.
|
|
|
13. In plants the cell wall is mostly composed of what?
|
13. In plants the cell wall is largely composed of cellulose.
|
|
|
14. What do we call the part of a cell that separates the cell from its surrounding environment?
|
14. The cell membrane separates the cell from its surrounding environment.
|
|
|
14. Does the cell membrane control the movement of materials into and out of the cell?
|
14. Yes! the cell membrane controls the movement of materials into and out of the cell.
|
|
|
15. What is the cell membrane made of?
|
15. The cell membrane is a two-layered structure made up of lipids, proteins, and carbohydrates.
|
|
|
16. What does it mean when a cell membrane is selectively permeable?
|
16. Selectively permeable means some substances can pass through the cell membrane freely.
|
|
|
17. What do we call the round, membrane-bound structure that serves as the control center for cell metabolism and reproduction?
|
17. The nucleus (plural, nuclei) is the control center for cells.
|
|
|
18. What is the membrane that surrounds the nucelus called?
|
18. Surrounding the nucleus of a membrane is the nuclear envelope.
|
|
|
19. What is within the nucleus of a cell and are the sites of production of ribosomes?
|
19. Nucleoli are within the nucleus and are the sites of jproduction of ribosomes.
|
|
|
20. What do we call the watery material lying within the cell between the cell membrane and the nucleus?
|
20. Cytoplasm is the watery material lying within the cell between the cell membrane and the nucleus.
|
|
|
21. What do we called the system of fluid-filled canals or channels enclosed by membranes?
|
21. The endoplasmic reticulum is the system of fluid-filled canals or channels enclosed by membranes.
|
|
|
22. What is the function or job of endoplasmic reticulum?
|
22. The canals of endoplasmic reticulum serve as paths for transport of materials through the cell.
|
|
|
23. What are ribosomes?
|
23. Ribosomes are small particles where protein synthesis takes place in the cell.
|
|
|
24. What is the part of the cell made up of stacks of flattened membrane sacs?
|
24. A Golgi body is made up of stacks of flattened sacs.
|
|
|
25. What does a Golgi body do?
|
25. Golgi bodies help with the preparation and storage of molecues to be secreted, or released, outside the cell.
|
|
|
26. What do we call the small, saclike structures surrounded by a single membrane and containing strong digestive enzymes?
|
26. Lysosomes are the small, saclike structures that contain strong digestive enzymes.
|
|
|
27. Where are lysosomes found?
|
27. Lysosomes are found in most animal cells and some plant cells.
|
|
|
28. What are the organelles called that release the energy in food molecuesl?
|
28. Mitrochondria is the name for the round, or slipper-shaped organelles that release the energy in food molecules for use by the cell.
