firm, protective structure that gives the cell its shape in plants and bacteria
cell wall
42
produces a usable form of energy for the cell
mitochondria
43
packages proteins within the cell and makes lipids
golgi apparatus

consist of hollow tubes which provide support for the cell
microtubules
49
small hair-like structures used for movement or sensing things
cillia
50
longer whip-like structures used for movement
flagella
51
Cells vary widely with respect to:
shape size number of organelles types of organelles
52
These specialized cells make up about 40–45% of the total volume of blood they have the important job of carrying oxygen from the lungs to all parts of the body
red blood cells
53
the specialized cells that have the important job of absorbing the water when it passes through the stomach to the intestines
intestinal lining cells
54
thousands of tiny finger-like projections that help in absorbing water in the intestinal lining cells by increasing the surface area so the cell can absorb water more quickly.
microvilli
55
these specialized cells store the energy from food for future use They are found under the skin and surrounding internal organs. they contain droplets of fat in the cytosol
fat cells
56
this specialized cell protects the surface of the body and cover the organs and body cavities within
epithelial cells
57
this specialized cell makes up the bones which support and protect the body
bone cells
58
