The Cell in It’s Environment Chapter 3 Section 2 The Cell in It’s Environment This section tells how things move into and out of cells.

Introduction The cell membrane is selectively-permeable, which means some substances can pass through it while others cannot.

DIFFUSION Three ways substances can move into and out of a cell: Osmosis Active transport

DIFFUSION In diffusion, molecules move from an area of HIGH concentration to an area of LOW concentration

DIFFUSION

DIFFUSION

OSMOSIS In osmosis, water molecules diffuse through a selectively permeable membrane.

ACTIVE TRANSPORT Two ways of moving things into and out of a cell that do NOT need energy are: Diffusion And Osmosis Moving materials across a cell membrane without using energy is called passive transport High Normal Low Outside Outside

ACTVE TRANSPORT Active transport moves materials from low to high and requires cell’s energy Passive transport moves material from high to low and does not require cell’s energy

ACTIVE TRANSPORT Two ways a cell move things through active transport (Transport protein) Engulfing Food Particle

ACTIVE TRANSPORT & PASSIVE TRANSPORT High Active Transport Passive Transport No energy needed ATP Energy needed Low

ACTIVE TRANSPORT & PASSIVE TRANSPORT Is the following sentence true or false? As a cell gets larger, it takes longer for a molecule that has entered the cell to reach the middle of the cell. TRUE
