nucleus

Back 2

contains DNA

vacuoles/vesticles

Back 3

store materials (salts, fats, carbohydrates)

Front 4

lysosomes

Back 4

break down and recycle macromolecules

Front 5

cytoskeleton

Back 5

maintains cell shape, moves cell parts, helps cells move`

Front 6

centrioles

Back 6

organize cell division

Front 7

ribosomes

Back 7

synthesize proteins

Front 8

rough ER

Back 8

synthesizes proteins and transports them

Front 9

smooth ER

Back 9

contains enzymes that preform specific tasks, transports materials

Front 10

golgi apparatus

Back 10

modifies, sorts, and packages proteins and lipids for storage or transport out of the cell

Front 11

chloroplasts

Back 11

convert solar energy to chemical energy stored in food

Front 12

mitochondria

Back 12

converts chemical energy in food into usable compounds

Front 13

cell wall

Back 13

shapes, supports, and protects the cell

cell membrane

Back 25

both, prokaryote

Front 26

lipid bilayer

Back 26

gives cell membranes its flexible structure that forms a strong barrier between the cell and its surroundings

Front 27

selectively permeable

Back 27

some substances can pass across them and others cannot

Front 28

cytoplasm

Back 28

portion of the cell outside the nucleus

Front 29

organelles

Back 29

cell structures that act like organs in the body

Front 30

cell theory

Back 30

1-all living things are made up of cells
2-cells are the basic units of structure and function in living things
3-new cells produced from existing cells

Front 31

diffusion

Back 31

the process by which particles move from an area of high concentration to an area of lower concentration to an area of lower concentration

Front 32

facilitated diffusion

Back 32

molecules that cannot directly diffuse across the membrane pass through special protein channels

Front 33

aquaporins

Back 33

water channel proteins that allow water to pass right through them

Front 34

osmosis

Back 34

diffusion of water through a selectively permeable membrane

Front 35

isotonic

Back 35

solutions on both sides of the membrane are equal

Front 36

hypertonic

Back 36

higher solute rate inside than out

Front 37

hypotonic

Back 37

higher solute rate outside than inside

Front 38

osmotic pressure

Back 38

the net movement of water out of or into a cell produces this force

Front 39

homeostasis

Back 39

relatively constant internal physical and chemical condition

Front 40

receptor

Back 40

a part of the cell that receives cellular signals from neighboring cells
