CHAPTER 7: Cell Structure and Function STARTS WITH ? Vocab Review
1. Small structure in a cell that performs a specific function = _O_ __ __ __ __ __ __ __ __
2. Dark spot in the nucleus where ribosomal RNA & proteins are made
=_N_ __ __ __ __ __ __ __ __
3. Sac of digestive enzymes involved in apoptosis = _L_ __ __ __ __ __ __ __
4. _R_ __ __ __ __ ER is covered by ribosomes and transports proteins to the Golgi apparatus.
5. The _C_ _ __ __ _W_ __ __ __ is found outside the cell membrane in plants and bacteria
and provides support and protection.
6. An organism like a green plant that can make its own food = _A_ __ __ __ __ __ __ __ __
7. These sausage shaped organelles burn glucose and store the energy as ATP
= _M_ __ __ __ __ __ __ __ __ __ __ __
8. The molecule used by cells to store genetic information = _D_ __ __
9. An organism whose cells have a nuclear membrane and organelles surrounded by membranes =
_E_ __ __ __ __ __ __ __ __
10. _C_ __ __ __ __ __ __ __ __ is the molecule that makes plant cell walls sturdy.
11. The _N_ __ __ __ __ __ __ is surrounded by a double membrane, contains the cells DNA,
and acts as the cell’s control center.
12. In some cells, one or two long hair-like structures called _F_ __ __ __ __ __ __ __
extend from the cell’s surface and help move the cell.
13. The _C_ __ __ __ __ __ __ __ __ consists of the gel-like material and organelles located
between the nucleus and cell membrane.
14. Smooth ER has several functions including regulating _C_ __ __ __ __ __ __ ions in muscle
cells, breaking down _T_ __ __ __ __ __ in liver cells, and making lipids like phospholipids
& _S_ __ __ __ __ __ __ __.
15. The folded inner membranes inside mitochondria are called _C_ __ __ __ __ __ __.
16. A cell membrane is called a _B_ __ __ __ __ __ __ because the phospholipids line up in
TWO ROWS with polar heads facing outward and hydrophobic tails facing inward.
17. The _P_ __ __ __ __ __ _M_ __ __ __ __ __ __ __ (also called the cell membrane)
surrounds all cells and is selectively permeable to control what enters and leaves the cell.
18. Ribosomes join _A_ __ __ __ __ _A_ __ __ __ subunits to make proteins.
19. Golgi bodies are made of stacks of membranes called _C_ __ __ __ __ __ __ __ __
20. ER is an abbreviation for
_E_ __ __ __ __ __ __ __ __ __ __
_R_ __ __ __ __ __ __ __ __
21. _S_ __ __ __ __ __ endoplasmic reticulum does NOT have ribosomes attached.
22. The _T_ __ __ __ __ __ __ __ __ sacs found inside chloroplasts are where
photosynthesis happens in plant cells.
23. A _P_ __ __ __ __ __ __ __ __ __ __ __ molecule has a polar head and two non-polar
tails and combine with proteins to make cell membranes.
24. A _G_ __ __ __ __
_B_ __ __ __ looks like stacks of pancakes and modifies, sorts,
and packages molecules for use in the cell or transport out of the cell.
25. _C_ __ __ __ __ __ is the molecule that makes fungi cell walls sturdy.
26. _I_ __ __ __ __ __ __ __ proteins stick into the cell membrane. They can go part way or
all the way through to the other side.
27. Space for storing food, water, enzymes, or waste = _V_ __ __ __ __ __ __
28. An organism (like you) that CAN’T make its own food and gets it energy by eating other
organisms = _H_ __ __ __ __ __ __ __ __ __ __
29. A _P_ __ __ __ __ __ __ __ __ __ is an organism with NO NUCLEAR MEMBRANE and
NO MEMBRANE BOUND ORGANELLES.
30. _R_ __ __ __ __ __ __ __ __ are small structures attached to Rough ER or free floating
in the cytoplasm that make proteins.
31. _P_ __ __ __ __ __ __ __ __ __ __ __ __ is the molecule that makes bacterial cell walls
sturdy.
32. _B_ __ __ __ __ __ __ __ are examples of cells that are PROKARYOTES.
33. The _C_ __ __ __ __ __ __ __ __ __ __ __ is made of microtubules and microfilaments in
the cytoplasm which provide support and give the cell its shape.
34. Molecule used by mitochondria to store energy = _A_ __ __
35. _C_ __ __ __ __ are many short hair-like structures on the surface of a cell that help
move the cell or move substances past the cell.
36. _C_ __ __ __ __ __ __ __ __ __ are log-like structures made of microtubules that appear
during cell division in animal cells and to organize the spindle & guide chromosomes apart.
37. _P_ __ __ __ __ __ __ __ __ __ proteins stick to the outside or inside surface of a cell
membrane.
38. _A_ __ __ __ __ __ __ __ __ is “programmed cell death” for the good of the organism.
39. MOTOR proteins walk along on the microtubules of the
_C_ __ __ __ __ __ __ __ __ __ __ __ and pull chromosomes apart during cell division.
40. Membranes are _S_ __ __ __ __ __ __ __ __ __ __ _P_ __ __ __ __ __ __ __ __
because they allow certain molecules to pass through but keep others out.
