Animal Cell Coloring Answers to Question at Bottom of Page
1. cell membrane: semipermeable (controls what goes in and out of the cell)
2. Endoplasmic reticulum - smooth makes fats and detoxifies alcohol and the rough contains ribosomes. Together ribosomes and rough ER make protein
3. ribosome - makes protein
4. Golgi apparatus - packages, labels, and exports molecules for transport
5. lysosome - breaks down waste
6. microtubule - part of cytoskeleton
7. mitochondria - provides energy for the cell in the form of ATP
8. nucleus - control center. has DNA to provide instructions for protein production
Plant Cell Coloring
1. Two things found in a plant cell not found in an animal cell are chloroplast and cell wall
2. A plant cell is square while an animal cell is not. This is due to its cell wall.
3. chloroplasts absorb light energy for the plant for it can make food through the process of photosynthesis
4. The vacuole stores water, food, and waste in the cell.

Characteristics of Proteins, Carbs, Lipids, and Nucleic Acids
Proteins are made of amino acids and and are used to build structures in the body or for certain functions
Lipids are made of fatty acids and are used for building structures and long term energy storage
Carbohydrates are made of simple sugars and are the body's preferred source of energy. Glucose is an example of a carbohydrate. It is what is broken down by the mitochondria to provide ATP
Nucleic acids - building blocks are nucleotides and these are molecules such as DNA and RNA that are used for information storage.
The ribosomes are attached to the rough ER. When proteins are made, they are began in the ribosome. The ribosome puts the amino acids in a chain. Then the rough ER folds the chain into its correct 3-D shape. If the protein is to be exported, it will then be sent to the Golgi apparatus.
Selectively permeable or semipermeable means the cell will let some things in but not others. In other words, the membrane controls what enters and leaves the cell.
The cell membrane contains a double layer of phospholipid molecules. These help control passage of substances in and out of the cell because their heads are phosphates and are attracted to water. Their tails are lipids and repel water. So we say the heads are hydrophilic (water-loving) and the tails hydrophobic (water fearing)
Viruses are very small. They only contain a protein head and either DNA or RNA. They do not have a cell membrane or any organelles.
Prokaryotic cells are smaller than eukaryotic. The only organelle they contain is ribosomes. They have a cell membrane and a cell wall.
Eukaryotic animal cells have a cell membrane but not a cell wall. They contain all other organelles except the chloroplast
Eukaryotic plant cells have a cell membrane and a cell wall. They also contain chloroplasts.
Humans have eukaryotic animal cells
ATP is the molecule the body uses for energy. It is produced by the mitochondria when glucose is broken down.
See cell transport notes. You are also responsible for knowing hypertonic, hypotonic, and isotonic terminology
