Academic Cell Structure and Function Test Review Key
** Some questions will come the from Ecology Test and Biomolecules**
1. What color does the starch turn if the dialysis sac is permeable to the iodine? Blue/Black
2. What is the structure that contains the cell’s genetic material? Nucleus
3. What is homeostasis? Process by which organism keep their internal conditions stable
4. Where are proteins assembled? Ribosomes
5. In plants what provides support and protect to the cell? Cell Wall
6. This organelle converts chemical energy into more convenient energy for the cell to use?
Mitochondrion
7.
Hypotonic
Hypotonic
Hypertonic
Hypotonic
Hypertonic
Isotonic
8. Referring to the diagram above: What process if being illustrated and what kind transport is being
shown. Endocytosis and Exocytosis/ Active transport
9. Why can prokaryotic cells divide quicker than Eukaryotic cell? Eukaryotic cells are more
structurally complex than prokaryotic cells.
10. What do lysosomes do for cell? Break down molecules in the cytoplasm
11. If a eukaryotic and prokaryotic cell had a dye add to each of them that stained only the nucleus
(nuclei), which type of cell would it be? Eukaryotic
12. What is the function of the cell membrane? Allows certain molecules to enter and exit the cell
13. Describe selective permeability? Selects what can enter and exit the cell
14. Identify which is the prokaryotic and eukaryotic below. Cell X is prokaryotic and cell Y is eukaryotic
Note: Eukaryotic cell are more complex that
prokaryotic cells therefore prokaryotic can
divide faster
15. What type of cell is described below in the concept map? Plant Cell
16. What is the movement of water displayed below? Osmosis
17. In the Sodium Potassium pump below what type of transport is used? (Active or Passive) and
explain
Active Transport
18. If a paramecium is placed in a hypertonic environment, what would happen and what organelle will
be used? Water will diffuse out of the paramecium
19. Circle each of the organelles that are responsible for the production of new molecules
Ribosomes—Endoplasmic reticulum—Vacuoles—Ribosomes—lysosomes--Golgi apparatuses—plastids
