The constant, random motion of molecules is called

Answer 1

Molecular motion

Question 2

the diffusion of water specifically is

Answer 2

osmosis

Question 3

What regulates materials that come into and out of a cell

Answer 3

The cell memebrane

Question 4

What are 2 words that best describe the cell membrane

Answer 4

Selectively permeable

Question 5

What are the substances dissolved in a solevent

Answer 5

Solutes

Question 6

A _____ is a mixture of evenly dispersed substances

Answer 6

Solution

Question 7

______ are proteins found within the cell membrane that help transport large molecules into and out of cells

Answer 7

Carrier protiens

Question 8

___ is a type of active transport that moves liquid into a cell

Answer 8

Penocytosis

Question 9

The state of _____ is the ultimate outcome of diffusion

Answer 9

Equilibrium

Question 10

What are the two main main differences between diffusion and active transport

Answer 10

1. ) Active transport expends energy from the cell while diffusion does not
2. ) Since diffusion is a type of passive transport, the concentration gradient moves downward while active transport’s concentration gradient moves upwards

Question 11

What is passive transport?

Answer 11

Substances crossing the cell membrane without using energy

Question 12

what are 2 examples of passive transport

Answer 12

Diffusion

plasmolysis

Question 13

what is concentration gradient

Answer 13

The difference in the concentration of molecules across a distance

Question 14

How does concentration gradient affect passive transport

Answer 14

concentration gradient is what helps substances move without energy. ( which is passive transport

Question 15

Semipermeable

Answer 15

It only lets certain subtances pass

Question 16

Hypotonic

Answer 16

The concentration of waterOUTSIDE the cell is bigger than inside

The concentration of soluteINSIDE the cell is bigger than outside

Question 17

Hypertonic

Answer 17

The concentration of water INSIDE the cell is bigger than outside

The concentration of solute OUTSIDE is bigger than inside

Question 18

Isotonic

Answer 18

When the concentration of solutes outside and inside the cell are =, and the water inside and outside the cell is=

Question 19

How do charged particles pass through the cell membrane

Answer 19

Active Transport

Question 20

Active transport

Answer 20

Substances crossing the cell membrane that need the use of energy

Question 21

Diffusion

Answer 21

The simplest type of passive transport. the movement of molecules from a higher concentration to a lower one

Question 22

Concentration gradient

Answer 22

the difference in the concentration of molecules across a distance

Question 23

The ____ of ______ depends on the relative concentration of solutes (solids)

Answer 23

Net direction

Osmosis

Question 24

Contractile vacuoles

Answer 24

specialized organelles that remove excess water by pumping it out (requires energy

Question 25

Turgor pressure

Answer 25

The pressure that water molecules exert against the cell wall ( occurs in plants) (prevents wilting)

Question 26

Plasmomolysis

Answer 26

When cells shrink while being in a hypertonic enviorment

Question 27

Cytolisis

Answer 27

whare water diffuses into a cell to the point of bursting

Question 28

facilitated diffusion

Answer 28

a type of passive transport - a process used transporting molecules that cannot diffuse rapidly through cell membranes

Question 29

Carrier Proteins

Answer 29

protiens located within the cell membrane that transports large molecules/molecules that cannot dissolve in lipids

Question 30

Endocytosis

Answer 30

the process by which cells ingest or take in large molecules or fluid by engulfing itand forming a vesicle around it

Question 31

Pinocytosis

Answer 31

Can engulf with fluids or solutes

Question 32

Phagocytosis

Answer 32

engulfs large solutes

Question 33

exocytosis

Answer 33

opposite of endocytosis. the process where cells rid themselves of debris
