Cells
What did Virchow do?
all new cells come from preexisting cells.
what is the main ingredient in cells?
water
nucleic acids
form when long chains of molecules called nucleotides are joined together.
examples of carbohydrates
- sugars
- starch
- cellulose
What did Schwann do?
concluded all animals were made of cells.
Can you see cells with the naked eye?
no
what is proteins?
- made of long chains of amino acid molecules.
functions of carbohydrates
- Supplies energy for cell process
- Short-term energy storage
- Needed for cell communication between cells
- Provides structural support.
What did Schleiden do?
concluded all plants were made of cells
The 3 principles of Cell Theory
1. all living things are made of one or more cells.
2. the cell is the smallest unit of life.
3. all new cells come from preexisting cell
Functions of Proteins
Help: cells communicate with other cells
Help: to break down nutrients
Move: substances around inside cells
Regulate: cell processes
Provide: structural support
functions of lipids
- provide protective barriers/membranes in cells.
- energy storage
- cell communications.
what did Hooke do?
1st to see cells in a microscope and gave cells their names.
what are macromolecules?
1. smaller molecules are joined together.
2. cells are made of smaller parts.
3. can't function without water. Why is because it's made of 75% of water. Four types of macromolecules nucleic acids, proteins, lipids, and carbohydrates.
what are lipids
large molecules that do not dissolve in water.
examples of lipids
-fats
- oils
- cholesterol
- Vitamin A
Scientists that contributed to cells
Hooke, Schleiden, Schwann, and Virchow
Four types of macromolecules
nucleic acids, proteins, lipids, and carbohydrates
examples of proteins
- hair
- horns
- feathers
- claws
- nails
what are carbohydrates
one sugar molecule, two sugar molecules, or a long chain of sugar molecules.
