Biology H-Mr.Willets
pg 69-72
1) Robert Hooke gave cells their name- What did he actually see? ______________________________
Who first saw living cells? ___________________________________
2) What are the three parts to the cell theory a) All living things are made of ____________
b)cells are the units of _______________ and _______________ in organisms
c) cells come from the ________________________________________
3) What three scientists provided the evidence for the cell theory? _____________________ ,
_______________________ , ____________________
4) Most cells are too small to be seen without a ______________________ The size of a cell is limited by the ratio between the ______________________________ and their ______________________
(look at the chart at the bottom of pg 70 and try to understand what is said in the paragraphs above it)
5) The variety of shapes of cells is related to the variety of _________________ these cells perform- In other words "_____________________________.(not in book but you know this phrase) Look at the examples at the top of pg 71
6) A cell component that performs a particular function for the cell is called an ___________________
7)The cell is surrounded by a thin ______________________ Inside the cell are organelles that are surround by their own _____________________ The _______________ contains most of the cell's __________________ information and directs cell activities.
8) Organisms whose cells have a nucleus and other organelles with their own membrane are called _________________________ One celled organisms whose cells do not have "membrane-bound organelles" are called _____________________ (membrane-bound means surrounded by a membrane)
Pg 73-75
9) What does the cell membrane control? _______________________ Because not all things can pass through the membrane, it is called ________________________________ (another phrase is semi-permeable)
10) Cell membranes are made mostly of what kind of lipid? ________________________
What other membrane lipid is found in animal cell membranes? _______________________
11) Also in the cell membrane are integral and peripheral _______________________
12) Because the lipids and proteins in the cell membrane can move around, we describe it as a
_________________________model.
pg 75-
13) Between the cell membrane and the nucleus is the _____________________. The fluid part of the cytoplasm is called the __________________
Use the chart on pg 75 to answer these questions
14) Which cell organelle synthesizes (makes) proteins? ____________________
15) Which cell organelle helps digest things? _______________________
16) Which cell organelle transfers energy to ATP? ______________________ (what this means is that this is where food is burned)
17) Which cell organelles help move cells and materials?_________________________________
18) Which cell organelle packages substances produced by the cell?__________________________
19) Which cell organelles help to support, move and divide cells? ______________________________
20) Which cell organelle stores genetic information, makes RNA and makes ribosomes? _______________
21) Which three cell organelles are found in plant cells but not
animal cells-____________________ ,
_____________________ , __________________ Which of these supports
and protects the cell?___________________ Which of these is used for
storage of wastes? _______________________ Which of these is involved
with storing food and transferring light energy to organic molecules
(making food)? __________________
The rest of the chapter gives details about these cell organelles- you may read these parts just for fun because you enjoy biology so much.
