Living things are made of cells.

• Living things obtain and use energy.
• Living things grow and develop.
• Living things reproduce.
• Living things respond to their environment.
• Living things adapt to their environment

All living organisms are composed of cells. They may be unicellular or multicellular.

The cell is the basic unit of life.

Cells arise from pre-existing cells.

Eukaryotic: All living things, DNA in nucleus,

Prokaryotic: Bacteria, DNA nucleoid

Plants: Cell wall, Larger Vacuole, Cytoplasm, chloroplast, ribosomes, Golgi complex, lysosome, smooth & rough ER, mitochondria nucleaus, Plasmodesmata, plastids,

Animals:  nucleus, Golgi complex, endoplasmic reticulum, ribosomes, mitochondria, peroxisomes, cytoskeleton, and cell (plasma) membrane, Centrioles,

RNA: Ribose sugar, Single stranded

DNA Deoxyribose Sugar, Double stranded

Genotype: Genetics

Phenotypes: Physical characteristics

Pyrimidine: Adenine and guanine

Purines: Cytosine, thymine, uracil

when atoms organize they make what ? When cells organize they make what ?

When tissues organize they make what?

Isotopes: They are still the same element. They are just a little different from every other atom of the same element. 

Ions: Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge.

Hydrogen Bonds?

Covelent Bonds?

Polar Covalent Bonds?

Ionic Bonds?

HB: a bond where hydro is strong in electronegativity

CB:  share a one atom

PCB: H2O share electrons

IB: attract - & + to make it neutral

Cohesive: same molecules that stick together

Adhesive: different molecules that stick together

Hydrophobic: dislikes water

Hydrophillic: likes water

Isomers: Isomers are compounds with the same molecular formula but different structural formulas. Isomers do not necessarily share similar properties, unless they also have the same functional groups

Enantiomers:are chiral molecules that are mirror images of one another. Furthermore, the molecules are non-superimposable on one another

IC: Red & white = PINK (blends)

CD: Red & White = White with red dots.

(shows both colors)

A trait associated with a gene that is carried only by the male or female parent.
