Question 1

Interstitial fluid

Answer 1

Extracellular fluid surrounding cells

Question 2

Cell membrane

Answer 2

Separates inside of cell from insterstitial fluid; the fence

Gates are made of proteins, receptors for hormones, channels, and cell identity markers

Question 3

Nucleus

Answer 3

Denser “think tank” surrounded by nuclear membrane

Question 4

Cytoplasm

Answer 4

Contains cytosol, organelles, and inclusions

Question 5

Inclusions

Answer 5

Non-living components (stored nutrients, melanin)

Question 6

Passive transport

Answer 6

W/o use of energy

Question 7

Active transport

Answer 7

Use ATP to transport

Question 8

Passive forms of movement

Answer 8

Diffusion - movement of ions from higher concentration to lower

Osmosis - movement of water across semipermeable membrane from higher to lower

Filtration - water forces across membrane due to hydrostatic pressure

Facilitated diffusion - big substances helped by carriers

Question 9

Active movement

Answer 9

Helped by ion pumps, move against concentration gradient

Question 10

Vesicular movement

Answer 10

Endocytosis - move into cell
Exocytosis - move out of cell

Question 11

Chromatid

Answer 11

Double helix strand of dna
