Biology CH 8.3 Osmosis

Movement of particles from high to low concentration.

• Diffusion, a form of passive Transport

• Difussion, a form of Active Transport

Osmosis is a form of ______________.

• Passive Transport because it does not require energy.

• Active Transport because it requires energy.

The diffusion or movement of WATER across a semi-permeable membrane from an area of low concentration t to an area of high concentration is_______________________

• osmosis

• diffusion

• endocytosis

• exocytosis

ALL living cells have this in common

• Nucleus
• Cell Membrane
• Cell Wall
• Mitochondria

NGSS.MS-LS1-5

A cell will __________________ in a hypotonic solution.

• swell and perhaps burst (lyse)
• shrink
• the size of the cell will not change
• the size of the cell will change from large to small and from small to large

Osmosis is the diffusion of _____ across a selectively permeable membrane.

• food
• air
• water
• oxygen

In the given scenario what will happen? An egg with a dissolved shell is placed in pure water for 48 hours.

• Water will move in and out of the cell equally, and the cell with neither shrink nor swell.

• The egg will gain water and swell.

• The egg will lose water and shrink.

An gummy bear placed in a hypertonic (salty) solution will

• Stay the same

• Shrink- get smaller

• Swell- get bigger
