cell transport

everything that enters or leaves the cell has to pass through which organelle?

• mythocondria

• nucleus

• cell membrane

the transport can be classified as:

• simple diffussion

• active and passive

• facilitated diffussion

active transport does not spend energy

• TRUE

• FALSE

passive transport can be classified as:

• simple and facilitated diffusion

• ultra filtration

• mass diffussion

which molecules cross in simple diffussion?

• Co2

• potassium

• ions

• O

why can't ions pass through the membrane in simple diffussion?

(write with capitals only)

in facilitated diffussion the passage of molecules depends on:

• benzene

• extracellular fluid

• integral membrane proteins

exocytosis is:

• the cell responds to a signal to release its products

• secretion of the material produced by cells

• constant secretion of material

phagocytosis is comparable with:

• drinking

• swallowing

• eating

pinocytosis is comparable with

• drinking

• swallowing

• eating
