Biology/bio7
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 7
1 GROWTH
The growth of an organism may involve
an increase in cell size and/or in
cell numbers.
Growth requires: MATERIALS (e.g.
protein), ENERGY and STIMULUS (e.g.
hormone).
PATTERNS OF GROWTH
Growth may be
continuous (though
at different
rates), with a
gradual increase in
mass and size.
Graph shows human
male:
Mass (kg) and
Age (years).

#
2 GROWTH
Growth may be discontinuous, with
periodic increases, such as occurs
with an insect.
This graph shows such a growth
pattern, arrows indicating moults.

3 GROWTH HORMONES
The mammalian growth hormone is made
in the PITUITARY gland.
Plant growth
hormone (AUXIN) can
be collected in
agar and used in
experiments, as
shown.

#
4 SKELETONS AND SUPPORT
Plants are supported by CELL WALLS,
TURGOR (osmotic pressure) and WOODY
XYLEM. Animals need some kind of
SKELETON.
This may be:
FLUID (e.g. earthworm)
HARD, EXTERNAL (e.g. arthropod)
HARD, INTERNAL (e.g. vertebrate)
#
5 HUMAN ARM/LEG
The arm and the leg have equivalent
bones, with the PATELLA or the
knee-cap extra in the leg.
The shoulder and
hip joints are BALL
and SOCKET, the
others HINGE.
The 'funny bone' is
the nerve over
the elbow.
p

#
6 ARTHROPOD
The insect skeleton is made of CHITIN
which acts as both skin and skeleton.
The insect body is divided into HEAD,
THORAX, ABDOMEN.
Thorax: Legs
(3 pairs)
Wings
(2 pairs)
The skeleton must
be replaced for
growth.

#
7 VERTEBRATE SKELETONS
FUNCTIONS:
1) Support of body and weight.
2) Shape, e.g. hand, wing,
streamlining.
3) Movement: with the attachment of
muscles, bones become
levers.
4) Protection of vital organs e.g.
brain.
5) Breathing: rib cage movements.
6) Making red blood cells, in bone
marrow.
7) Sound conduction in middle ear.
#
8 VERTEBRATE SKELETONS
Organisation: Skull, Vertebrae, Ribs,
Limbs, Limb Girdles (Pelvic and
Pectoral).
Joint Types: Fixed or Synovial, Ball
and Socket, Hinge, Sliding.
Diagram shows
hinge joint detail.

#
9 MUSCLES AND MOVEMENT
Muscles can only do work when
contracting. They are arranged in
'ANTAGONISTIC' pairs. For example,
BICEPS bends the elbow joint, TRICEPS
straightens it.
There are three types of mammalian
muscle: SKELETAL, SMOOTH and CARDIAC.
#
10 SKELETAL
SKELETAL, STRIATED and VOLUNTARY
muscle is attached to the bones by
inelastic tendons.
It is under conscious control and
contains large numbers
of MITOCHONDRIA
(for energy
conversion)
and red MYOGLOBIN.
p
5
#
11 SMOOTH MUSCLE
SMOOTH MUSCLE is INVOLUNTARY. It is
stimulated by the AUTONOMIC NERVOUS
SYSTEM and is not under conscious
control.
Examples are walls of
arteries and the
muscles of the gut.
p
6
#
12 CARDIAC MUSCLE
CARDIAC MUSCLE is found only in the
heart. It is similar to skeletal
muscle, but has branched fibres. The
fibres contract in time due to the
pacemaker.
Diagram shows E.C.G.
(electocardiogram).
p
7
#
13 FLIGHT MUSCLES
Birds have very large flight
(PECTORAL) muscles to lift and lower
the wings.
Insects also have
paired flight muscles,
with some operating
indirectly by squeezing
the thorax.
