Triple Biology
Unit 1
- LUNGS
- WHEN BREATH IN, the chest
expands, cavity increases
reducing the pressure inside,
THE DIAPHRAM moves down
and ribs move up and out
- WHEN BREATHING OUT,
volume of cavity
decreases, increasing
pressure forcing air out.
diaphram up, ribs
contract and down.
- Alveoli
- large surface area, thin cell
membrane, good blood
supply, many of them
- gaseous exchange occurs here
- exchange CO2 OUT of the bloodstream,
O2 INTO the blood stream
- blood capillary
- blood capillary
- large surface area, thin cell
membrane, good blood
supply, many of them
- ADAPTED
- 2 smaller lungs, increase surface
area. moist lining , lungs expand, 2
large surface area, easier absorbtion
of air. small alveoli with large surface
area. very thin cell membrane easy to
absorb oxygen and transport it.

- DIFFUSION/ACTIVE TRANSPORT/OSMOSIS
- Diffusion
- diffusion is the spreading
out of particles from an area
of high concentration to an
area of low concentration
- happens in
- plants
- photosynthesis, water movement.
- photosynthesis, water movement.
- animals
- lungs, digestion
- lungs, digestion
- plants
- diffusion is the spreading
out of particles from an area
of high concentration to an
area of low concentration
- Active Transport
- opposite to Diffusion and uses energy
from respiration, from a low
concentration to a high concentration
- happens in
- gut, plant roots
- gut, plant roots
- happens in
- opposite to Diffusion and uses energy
from respiration, from a low
concentration to a high concentration
- Osmosis
- Osmosis is the movement
of WATER molecules
across a PARTIALLY
PERMEABLE MEMBRANE
from a region of HIGH
WATER CONCENTRATION
to a region of LOW WATER
CONCENTRATION
- Osmosis is the movement
of WATER molecules
across a PARTIALLY
PERMEABLE MEMBRANE
from a region of HIGH
WATER CONCENTRATION
to a region of LOW WATER
CONCENTRATION
- Phloem
- Sugar Transportation
- living cells
- need energy which is
transported from cell
to cell in the form of
dissolved sugars
- Sugar Transportation
- Diffusion
- GUT
- VILLI
- big SURFACE
AREA, single
layer of surface
cells. v.good
blood supply
- digested food absorded more easily
- digested food absorded more easily
- small intestine
- big SURFACE
AREA, single
layer of surface
cells. v.good
blood supply
- VILLI
- Absorbtion in Plants
- stoma/stomata in
the leaf takes in CO2
- spongy - absorbs water,
- holes underside of leaf.
- spongy - absorbs water,
- Plant Transport
- root hair cell
- have thin cell
membranes, large
surface area and
good transport.
- have thin cell
membranes, large

- root hair cell
- stoma/stomata in
the leaf takes in CO2
- Photosynthesis
- CARBON DIOXIDE + WATER => OXYGEN+GLUCOSE
- light + chlorophyll
- CARBON DIOXIDE + WATER => OXYGEN+GLUCOSE
- Xylem
- dead hollow tubes
- water and mineral transportation
- strong-help support the plant
- dead hollow tubes
- Transpiration
- the rate of
transpiration is how
water moves through
the plant.
- Affected by:
light intensity,
temperature,
air movement,
decrease in
humidity
- Affected by:
light intensity,
temperature,
air movement,
decrease in
humidity
- as light intensifies, more
stomata open up, however
when all stomata are open, the
rate of transipation cannot increase.
- the rate of
transpiration is how
water moves through
the plant.
