1. lysosome
2. endoplasmic reticulum
3. chromosome (DNA)
4. golgi body (apparatus)
5. vacuole
6. mitochondria
7. ribosome
8. nucleolus
9. nucleus (nuclear membrane would also be OK)
10. centrioles
11. plasma membrane
12. cytoplasm

NOTES & TIPS :
#1 - generally, lysosomes are illustrated as "shaded-in" circles or ovals.
#2 - channels running through the cytoplasm
#3 - the genetic material of the cell. humans have 46 chromosomes in each body cell (except eggs & sperm). this cell is eukaryotic because its genetic material is inside a nucleus.
#4 - stacks of membranes (like pancakes)
#5 - an "empty" oval or circle
#6 - you can recognize the mitochondria by the zig-zag line that is usually drawn in them. these represent internal membranes where respiration reactions occur.
#7 - very small dots, sometimes on the endoplasmic reticulum, sometimes out floating in cytoplasm
#8 - drawn as a dark circle inside the nucleus
#9 - generally depicted as the largest "shaded-in" circle inside the cell
#10 - drawn in pairs, two cylinder-like structures at right angles to each other
#11 - the outer boundary
#12 - the watery fluid that everything else floats in

Prokaryotic Cells
Have a cell wall
Are small
Plasma Membrane enclosing cytoplasm and DNA
No Nucleus
No organized internal structure
bacteria
can give rise to 5 billion progeny
can duplicate in 20 min
some can live on inorganic substances
are Archea (extreme environments) and Eubacteria (soil, illnesses)

Eukaryotic Cells
make up plants animals and fungi
larger
organized
have a nucleus
organelles
