1
The spreading out of
particles from an area of
high concentration to an
area of low concentration.
2
These are where
photosynthesis occurs. They
contain green chlorophyll.
3
A cell with a cell wall and
cell membrane but no
nucleus; the DNA is loose in
the cytoplasm.
4
A gamete with lots of
mitochondria and enzymes.
5
CO2 + H2O  C6H12O6 + O2
6
Whichever one of the conditions
required for photosynthesis is in
the shortest supply.
7
Damage an enzyme irreversibly
by changing its shape.
8
Plants store this in seeds or as
starch, make cell walls from it,
convert it to protein and use it
for respiration.
9
A square frame enclosing a
known area.
10
Mean no of organisms per m2 x
total area (m2)
11
Repeatable and Reproducible.
Increasing sample size will
increase this.
12
Used for biological catalysts,
muscles, hormones and
antibodies.
13
Breaking down large insoluble
molecules into small soluble
molecules that can be absorbed
into the blood and used by the
body.
14
C6H12O6 + O2  CO2 + H2O
15
Releasing energy from food for
building up large molecules
from smaller ones, contracting
muscles to move, maintaining
constant body temperature etc
16
Cell division producing 2
identical daughter cells.
17
Undifferentiated cells found in
early human embryos and bone
marrow.
18
A way to show the genotype of
offspring from genetic crosses.
Dominant and recessive alleles
are identified using capital and
lower case letters.
19
The remains of plants and
animals made from the gradual
replacement of hard parts with
minerals (or from casts and
impressions or, by preservation
when no decay occurs).
20
This occurs when populations of
the same species become so
different they can no longer
breed together. Often due to
physical separation.
Diffusion
The spreading out of
particles from an area of
high concentration to an
area of low concentration.

These are where
photosynthesis occurs. They

Limiting factor
Whichever one of the conditions
required for photosynthesis is in
the shortest supply.
