The attraction among molecules of different substance, water molecules, water molecules stick to each other things. Is responsible for the upward curve on water’s surface
Adhesion
Is a substance that dissolves in a solvent.
Solute
the attraction among molecules of a substance. For hydrogen bonds make water stick to each other
Cohesion
Is the substance that is present in the greater amount and they dissolve another surface
Solvent
When one substance dissolves in another, is a mixture of substances that is the same throughout it is a homeostasis mixture
This is divided in solvent and solute
Solution
Is a large molecule or macromolecule made of many monomers bonded together.
Polymer
Is often called block of life because carbon atoms are the basics of most molecules that make up living things. Its atomic structure gives it bonding properties that are unique among elements
It’s structures are: branched, chains, and rings
Carbon
Are non-polar molecules that includes fats, oils, and cholesterol.
Lipids
Are molecules compound of carbon, hydrogen and oxygen, they include sugar and starches
Carbohydrates
One of the sugars made by plants cell during photosynthesis is another six-carbon sugar
Glucose
Consists of glycerol, two fatty acids, and a phosphate group (po4) that is part of the polar head of the molecule
Phospholipid
Detailed instructions to build proteins are stored in extremely long carbon-based molecules
Nucleic acids
Are the most varied of the carbon-based molecules in organism
Proteins
Are molecules that contain carbon, hydrogen, oxygen, nitrogen, and sulfur
Amino acids
There are two types of nuclei can acids:
DNA and RNA
Helps to build proteins
RNA
Stores the information for putting amino acids together to make proteins
DNA
He made better lenses, he observed cells in greater detail
Leeuwenhoek (1674)
He concluded that all the living things are made of cells
Shawnn (1839)
Was the first to note that plants are made of cells
Shleiden (1838)
Proposed that all cells come from other cells
Virchow (1855)
Was the first to identify cells, and he named them
Hooke (1665)
Have a nucleus and other membrane bound organelles
Eukaryotic cells
Do not have a nucleus or other membrane-bound organelles
Procayotic cells
