and
2) TRUE or FALSE (circle one). Prokaryotes do not have cytoplasm.
3) Define ORGANELLE: __________________________________________________________________
4) Describe how a cell can be compared to a factory.
5) What is the function of CHROMOSOMES?
6) What is the threadlike form of chromosomes that is spread throughout the nucleus of a cell?
_________________________
7) Where are RIBOSOMES produced?

12) Compare microtubules and microfilaments.(in terms of structure &
function differences)
Organelles That Build Proteins
13) Using Figure 7-11 on pages 200-201, describe how proteins are made, completed, & transported.
14) Why is the rough ER “rough”?
What is the function of the rough ER?
15) What is the function of the smooth ER?
16) How is the Golgi apparatus like a post office?
Organelles That Capture and Release Energy
17) a) Which organelle captures the energy from sunlight?
b) Which organisms contain this organelle?
18) a) Which organelle is responsible for releasing stored chemical energy?
b) TRUE or FALSE (circle one). Only animal cells have mitochondria within their cells.
19) Which parent do you inherit all of your mitochondria from? ____________________
Cellular Boundaries
20) Which of these organisms can have a cell wall: prokaryotes, eukaryotes, both, or neither?
21) What is the function of the CELL WALL?
22) Why are most cell walls porous?
23) How many layers of lipids does a cell membrane have?
24) Using Figure 7-13 on page 204, draw a picture of a lipid
from the cell membrane and identify which part is hydrophilic
and which is hydrophobic.
25) Why is the cell membrane referred to as a fluid mosaic? What part of the cell membrane acts like a fluid?
And which cell-membrane components make it like a mosaic?
26) Define SELECTIVELY PERMEABLE:
