Natural Selection
the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.

BELOW are several examples of successful CELL CITY PROJECTS
BELOW are TWO videos that explains the concept of the CELL CITY metaphor:

Large Central Vacuole: stores food and water for the cell (Plant Cells only)
Lysosome: recycles waste in the cell
Golgi Apparatus: packages and distributes proteins
Vesicle: transports proteins around the cell

How are plant and animal cells different?
LET'S RAP!
WATER!
is one of the most important substances in cells!
Cells are 70% water!
Water helps to insulate the body and maintain homeostasis (stable internal environment)
The 4 Macromolecules
1. Nucleic Acids (ex. DNA, RNA)
2. Lipids (ex. cholesterol, vitamin A, phospholipids)
3. Carbohydrates (ex. starches, sugar)
4. Proteins (ex. keratin, amylase)
Cell Theory:
(Scleiden, Schwann, and Vichow)
1. All living things are made of one or more cells
2. Cells are the smallest unit of life
3. All cells come from preexisting cells
