c)___________________________________________________________________________
pg 65
3)Eukaryotic cells contain a _____________________ and membrane bound ___________________.
What types of organisms have these types of cells? _____________________________________
Cells that don't have these structures are called ____________________________What organisms have these cells? _______________________________
Pg. 66
4) What are the three main parts of eukaryotic cells?a)__________________,
b)__________________________ c)_______________________
5) What chemical is found in the nucleus? _____________ What is the function of the nucleus? ____________________________________________
6) Which part of a cell is semi-permeable? _____________________________ What does semi-permeable mean? _____________________________________________
Pg. 67
7) What name is given to the motion of cytoplasm within the cell? ____________________________
8) What name is given to the "little organs" found in the cytoplasm? __________________________
9) Cytoplasm is a jelly like material-in other words, it is a __________________ (not in the book)
10) The most numerous organelles are the _____________________. What is made here? __________
Pg. 68
11) What does ER stand for? ___________________________ What does rough ER have on it? ______________________ Smooth ER functions mostly as what? ___________________________
12) The ______________________________ is the processing, packaging and secreting organelle of the cell. (secreting means that chemicals leave the cell to be used elsewhere)
Pg. 69
13) Mitochondria are able to ______________, _______________ or fuse (join) with one another.
Mitochondria are the _______________________ centers of the cell. Chemical reactions within mitochondria _____________________________ from nutrients taken into the cell. In other words, this is where food is _________________ to release _________________.

_________________________.
15) The two types of protein strands are __________________________ and _______________________________ Together they form the _____________________ or framework of the cell (they give it shape and help things to move around inside)
Pg. 71

Pg. 72
17) The nucleoplasm (material inside the nucleus) contains fine strands called ____________________
These strands coil up when a cell ____________________________. when they are coiled up, they can be seen with the microscope and are called ________________________________. These are made mostly of ____________
18) Most nuclei (plural of nucleus) contain at least one ______________________. This is where ribosomes are made.

support and protect the cell b) fluid filled cavities called _____________________ c) large organelles
called _________________

a) ____________________________-these contain the green pigment _____________________
that absorbs __________________________ as the first part of photosynthesis.
b) ____________________________-these make and store ______________________ which give plants their ________________. What parts of plants would probably have cells with lots of these plastids? (not in book- think COLOR)_______________________________________

24) Organs are several types of ______________________ that work together
25) A group of organs that work together is called an ________________________________
26) Define colonial organism________________________________________________________
(these are not multicellular because the individual cells do not depend on each other very much)
