List 3 properties of water
-Polar -expands when freezes -can be three states: liquid, solid, or gas
200
Explain the types of passive transport
Osmosis- the diffusion of water Facilitated diffusion- passive transport of materials across the membrane using transport proteins Diffusion- the diffusion of any molecule
200
Two atoms that share electrons are held together by _____ bonds.
Covalent bonds
200
Compare and contrast the difference between osmosis and diffusion.
Osmosis: -specifically for h2o -powered by diffusion -protein: aquapoin Diffusion: -Amy small molecule -only uses a protein in facilitated diffusion Both: -passive transport -high to low concentration gradient -no ATP
200
Draw and label a chromosome.
Make sure it includes: -sister chromatin -centromere
200
What is the cell theory?
-all things come from pre-existing cells -cells come from other cells -cells are the basic unit of structure and function
300
Explain the difference between active and passive transport.
Active transport requires energy, while passive doesn't.
300
In a cell, the sites of protein synthesis are the _____, while the network of tiny rods and filaments that form a framework for the cell is called the _______. (Ribosomes, cytoskeleton, chloroplast, chlorophyll)
1.Ribosomes 2. Cytoskeleton
300
List and describe the phases of mitosis.
Prophase: -nucleus disappears -chromatin condenses into chromosomes -spindle forms from the centrioles Metaphase: -spindle attaches to the centromere -chromosome line up to the equator of the cell Anaphase: -spindle pulls the chromosomes apart Telophase: -nucleus reappears -chromosomes unwind into chromatin -spindle breaks down
300
Draw and label a phospholipid
Make sure it includes: Head- polar, hydrophilic, glycerol and phosphate group Tail- non-polar, hydrophobic, 2 fatty acid tails
300
What are the phases of the cell cycle?
Interphase, mitosis, cytokinesis
400
Compare and contrast animal and plant cells
Animal: -smaller vacuoles -centrioles Plant: -chloroplast -larger vacuoles Both: -nucleus -plasma membrane
400
A result of changes in one or more of the genes that produce substances that are involved in controlling the cell cycle. (Mitosis, Cholesterol, Cancer, macromolecule)
What is cancer
400
List and describe the phases of the cell cycle.
Interphase: G1- cell grows, makes lots of protein S- chromosomes duplicated G2- makes organelles, gets ready to divide
400
Draw and label a fluid mosaic model. Be sure to include the polar region, non-polar region, protein, and cholesterol
Answers may vary.

List one example of something saturated and one of something unsaturated
Saturated: butter Unsaturated: olive oil
500
Compare and contrast prokaryotic and eukaryotic cells.
Prokaryotic: -no membrane bound organelles -no nucleus -only organelle: ribosomes -cell wall Eukaryotic: -has membrane bound organelles -nucleus -has multiple organelles -only plant cells have cell wall Both: -ribosome -plasma membrane -flagella -cytoplasm -cilia
500
A molecule with an unequal distribution of charge is_________. A protein that speeds up chemical reaction is_________. (Polar molecules, enzyme)
1. Enzyme 2. Polar molecules

Draw and label the carbon cycle
House: combustion, gives off CO2 Cow: animals respire and gives of CO2 Green plants: absorb h2o, let out oxygen Decomposed matter gives off CO2
