1. nucleus a part of the cell containing DNA and RNA and responsi-
ble for growth and reproduction
2. ribosomes non membrane bounded organelles responsible for pro-
tein synthesis
3. endoplasmic ret- a system of membranes that is found in a cell's cytoplasm
iclum and that assists in the production, processing, and trans-
port of proteins and in the production of lipids
4. golgi bodies They receive proteins and other newlly formed materials
from the ER, package them, and distribute them to other
parts of the cell
5. lysosomes filled with enzymes used to break down food into particles
that can be used
6. vacuoles saclike structures that store materials such as water,
salts, proteins, and carbohydrates in the cytoplasm
7. mitochondia "power plants" of the cell; contain enzymes and genera-
tors that break down food molecules and use the energy
released to produce ATP
8. chloroplasts organelles that capture the energy from sunlight and con-
vert it into chemical energy in a process called photosyn-
thesis
9. cytoskeleton a microscopic network of actin filaments and microtubules
in the cytoplasm of many living cells that gives the cell
shape and coherence
10. cilia short structures projecting from a cell and containing
bundles of microtubules that move a cell through its sur-
roundings or move fluid over the cell's surface
11. cell membrane thin, flexible barrier around a cell, regulates what enters
and leaves the cell
12. cell wall

a rigid layer of nonliving material that surrounds the cells
of plants and some other organisms
13. diffusion process by which molecules tend to move from an area
where they are more concentrated to an area where they
are less concentrated
14. osmosis diffusion of water
15. isotonic (used of solutions) having the same or equal osmotic
pressure
16. hypotonic describes a solution whose solute concentration is lower
than the solute concentration inside a cell
17. hypertonic describes a solution whose solute concentration is higher
than the solute concentration inside a cell
18. passive trans- The movement of materials through a cell membrane
port without using energy
19. active transport transport of a substance (as a protein or drug) across
a cell membrane against the concentration gradient, re-
quires energy
20. prokaryotes single-celled organisms that do not have a mem-
brane-bound nucleus
21. eukaryotes organisms made up of one or more cells that have a
nucleus and membrane-bound organelles
22. organic being or relating to or derived from or having properties
characteristic of living organisms
23. carbohydrates main source of energy for the body
24. monosaccha- The building blocks of carbohydrates are single sugars
rides such as glucose and fructose.
