This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

BIOLOGY 8
1 OSMOSIS AND THE ROOT
Osmosis is vital in all living
organisms. It is a process of water
movement. Normally, substances diffuse
from areas of high concentration to
low concentration. Water can diffuse
across cell membranes, but not many
solute molecules. The membrane is
therefore called selectively
permeable. This water diffusion is
called Osmosis.
#
2 OSMOSIS EXPLAINED
Cells are slightly salty/sugary (1%).
In a 1% solution, nothing happens.
In pure water (0%), substances would
diffuse out of the cell .... but
membrane prevents this.
Water diffuses
IN.
The Cell SWELLS
and if there is
no restricting
wall, may burst.
p
0
#
3 OSMOSIS (STRONG SOLUTIONS)
In STRONG SOLUTIONS, substances cannot
enter through the membrane; water
diffuses OUT of the cell and the CELLS
SHRINK.
Note:
Swelling of plant cells
= TURGOR,
Shrinking = PLASMOLYSIS
p
1
#
4 ROOTS
Roots have very many root hair cells.
This gives a very large surface for
absorption.
Water enters by osmosis
and then passes up the
xylem of root and stem.
Salts enter the root by
an active transport
mechanism.

#
5 TRANSPIRATION AND THE LEAF
A leaf's main function is
PHOTOSYNTHESIS: for this it must also
perform gas exchange, losing water by
evaporation as a consequence -
TRANSPIRATION. This results in a
stream of water being drawn through
the plant.
o
E L R
E
EXPERIMENTS
1) Weighing whole or
part of a plant
measures water loss.
2) Cobalt chloride
paper on leaf turns
from blue to pink
with water vapour.
3) Potometer
measures water
uptake (as shown).

LEAF STRUCTURE
WATERPROOF CUTICLE.
Layer of epidermis
PALISADE cells:
main site of
photosynthesis.
Many CHLOROPLAST.
SPONGY MESOPHYLL:
air spaces, large
surface.
STOMATAL openings
and GUARD cells.
p
4
R
TRANSPIRATION rate
can be controlled by
opening/closing the
STOMATA. This is
done by osmotic
pressure changes in
the GUARD cells.
The rate of
transpiration
is affected by
LIGHT, WIND SPEED,
HUMIDITY and
TEMPERATURE.

6 KIDNEY
Mammalian kidney has two functions:
1) removal of wastes: EXCRETION
2) water/salt balance: OSMOREGULATION
The main excretory product, UREA, is
made in the liver from amino-acids.
o
F H
F
HOW THE KIDNEY WORKS
Blood under pressure
enters the GLOMERULI
where all but cells
and protein is
filtered.
Useful materials are
then reabsorbed into
the blood.
Urine passes to the
bladder.
