Front 1

Metabolism

Back 1

process by which organisms use energy, a requirement to maintain homeostasis

Front 2

Eukaryotes

Back 2

Membrane bound nucleus, organelles, and a semi permeable membrane around the cell

Front 3

Characteristics common to all forms of life

Back 3

1. Organization (unicellular vs. multicellular organisms that start as a single cell that multiplies and differentiates according to its role dictated by genes)
2. Energy Use (homeostasis and metabolism)
3. Reproduction (Production of new organism similar to original by passage of DNA containing genes for information about cell function)
4. Adaptation to the environment (natural selection)
5. Homeostasis (using passive transport through semi permeable membrane)

Front 4

Passive transport

Back 4

Through diffusion or the transfer of molecules from high to low concentration using only kinetic energy, results from collisions that change molecule direction to lower gradient

Front 5

Osmosis

Back 5

Water molecules moving down concentration gradent

Front 6

Hypotonic

Back 6

a solution if the concentration outside is lower than inside the cell and water moves into the cell by way of osmosis to establish equilibrium

Front 7

hypertonic

Back 7

a solution if the concentration outside is higher than inside the cell and water moves out of the cell by way of osmosis to establish equilibrium

Front 8

Isotonic

Back 8

water moves in and out of the cell equally because solute concentration is equal

Front 9

Osmotic Pressure

Back 9

solute particles on sides of a membrane create a pressure that is proportional to the concentration and independent of the particle

Front 10

Facilitated Diffusion

Back 10

molecules can't move down concentration gradient and use carrier proteins to cross

Front 11

Active Transport

Back 11

To go up a concentration gradient requiring energy. Possibly involving use of carrier protein pumps ex: sodium potassium pump

Front 12

Endocytosis

Back 12

Active transport across a cell where substance is enclosed in the cell membrane and pouch closes off and moves into cell as membrane bound organelle

Front 13

Exocytosis

Back 13

Active transport of membrane bound organelle fusing to cell membrane and releasing contents external to cell

Front 14

Pure traits

Back 14

offspring always have the same trait as parent

Front 15

Homozygous dominant trait and homozygous recessive trait

Back 15

All offspring show dominant trait

Front 16

homozygous dominant trait and heterozygous

Back 16

offspring all have dominant trait

Front 17

heterozygous and homozygous recessive trait

Back 17

50% chance offspring will have dominant trait and 50% chance of recessive

Front 18

heterozygous and heterozygous

Back 18

25% will have recessive trait
