Molecules that speed up chemical reactions

Large molecules that are made up of smaller units

Living things and all the macromolecules are made of this element

This macromolecule gives short term energy and includes sugars and starches

This macromolecule gives long term energy and includes fats, oils and cholesterol

This macromolecule’s function is determined by it’s structure.

This Macromolecule includes DNA and RNA

This is the monomer of Carbohydrates

Sugar

Enzyme

Enzymes lower this in order to speed up chemical reactions.

This property of water enables it to stick together and move upward against gravity from the roots of plant to the leaves for photosynthesis.

This is a monomer of a lipid. They are Non- polar.

Water is __________. Which means it has oppositely charged regions.

Lipids are ______________ Lipids are ______________. Which means the molecule is the same charge throughout.

The monomers of Proteins are ____________ The monomers of Proteins are ____________. There are 20 in all that make up living things.

This theory was disproved by Virchow who said all cells come from pre-existing cells.

This type of Nucleic Acid is responsible for making proteins.

This type of Nucleic Acid is responsible for storing genetic information.

This is a Nitrogen Base that bonds with Thymine.

This is a Nitrogen Base that bonds with Guanine.

This is an organelle that is only found in plant cells and is responsible for converting solar energy into usable energy for the cell.

This organelle is the site of protein synthesis.

This organelle stores DNA in a Eukaryotic cell.

This organelle stores materials such as water, waste and other minerals. It is the largest organelle in a plant cell.

This organelle provides support and structure in a plant cell.

This organelle is located in all cells, both Prokaryotic and Eukaryotic cells. It’s functions are to protect the cell and to decide what can enter and leave the cell.

The Cell Membrane’s structure consists of mostly a ______________ ___________.

This property of water allows water to dissolve substances and create solutions that can travel through the cell membrane and throughout all living things.

This property of water allows ice to float and living organisms under the ice to live.

This property of water is the reason why our bodies contain so much water and are able to maintain homeostasis and why the earth’s oceans and lakes can help it remain stable.

This type of cell is complex, it contains a nucleus and membrane bound organelles.

This type of cell is simple in complexity, it does not contain a nucleus or membrane bound organelles.

This is a type of transport through the cell membrane that requires energy in the form of ATP. It moves from low concentration to high concentration.

This type of transport through the cell membrane requires no energy This type of transport through the cell membrane requires no energy. It includes diffusion and osmosis. It moves from high concentration to low concentration to create equilibrium.

The diffusion of water through a semipermeable membrane from high concentration to low concentration.

The type of bond water molecules form from the positively charged hydrogen atom to the negatively charged oxygen atom.

These are the molecules that react together when an enzyme attaches itself and speeds up a chemical reaction.

These are the monomers of Nucleic Acids These are the monomers of Nucleic Acids. They consist of a Sugar, Phosphate and Nitrogen Base.

This was the invention that helped to produce the Cell Theory

This organelle is the jelly-like substance that fills in the cell and holds all the other organelles in place.

This organelle is the power house of the Eukaryotic cell This organelle is the power house of the Eukaryotic cell. It is where cellular respiration occurs and it converts glucose into usable energy for the cell.
