Cell - THE CORRECT ANSWER-Basic unit of all living organism


Cellular respiration - THE CORRECT ANSWER-Respiration which takes
place in the cytoplasm and mitochondria of the cells


Cellulose cell wall - THE CORRECT ANSWER-The rigid cell wall which
surrounds plant cell


Chlorophyll - THE CORRECT ANSWER-The green pigment contained in
the chloroplast which captures light energy from the sun


Chloroplast - THE CORRECT ANSWER-The plant organelles which
contain chlorophyll. They are the site of photosynthesis


Clone - THE CORRECT ANSWER-Offspring produces by asexual
reproduction which are identical to their parent organism


Codominance - THE CORRECT ANSWER-Two alleles which are both
expressed in the phenotype of an offspring

,Consumers - THE CORRECT ANSWER-Organisms which feed on other
organisms, eg. Primary eats plants, secondary consumers eat
herbivores


Cytoplasm - THE CORRECT ANSWER-The water-based gel in which the
organelles of all living cells are suspended


Decomposers - THE CORRECT ANSWER-Microorganisms that break
down water products and dead bodies


Denatures - THE CORRECT ANSWER-The breakdown of the structure
of a protein molecule if the temperature gets too hot or the pH
changes


Diastole - THE CORRECT ANSWER-The stage of the cardiac cycle when
the heart fills with blood-relaxation period of a heart beat


Differentiate - THE CORRECT ANSWER-The process by which
unspecialised cells become specialised for a particular function


Diffusion - THE CORRECT ANSWER-The net movement of the particles
of a gas or a solute from an area of high concentration to an
area of low concentration, down a concentration gradient


Diploid - THE CORRECT ANSWER-Having 2 sets of chromosomes in
the nucleus of the cells: one from the male parent and one from
the female

,Disperse - THE CORRECT ANSWER-The spreading of seeds away from
the parent plant to avoid competition.


Dominant - THE CORRECT ANSWER-A characteristic which will show
up in the offspring even if only one of the alleles is inherited


Double circulation - THE CORRECT ANSWER-The separate circulation
of blood from the heart to the lungs and then back to the heart
again and from the heart to the body and back to the heart
again


Ecosystem - THE CORRECT ANSWER-All of the animals and plants
living in an area, along with the things what affect them, such
as soil and the weather. An ecosystem includes all the
interactions between the many different types of living
organisms and the non-living components


Egestion - THE CORRECT ANSWER-The removal of undigested food
from a cell or from the body in the form of faeces


Endocrine glands - THE CORRECT ANSWER-The glands which produce
hormones and secrete them directly into the blood


Enzyme - THE CORRECT ANSWER-A protein molecule which acts as a
biological catalyst, speeding up the rate of a specific reaction
without being used up or affected. Enzymes are sensitive to
both temperature an pH

, Eutrophication - THE CORRECT ANSWER-When a lake or a river
becomes enriched with nutrients, e.g from fertiliser applied to
fields, excess plant growth is followed by decay.
Microorganisms use up oxygen from the water so that other
organisms can no longer survive


Fermentation - THE CORRECT ANSWER-Another term for anaerobic
respiration which is particularly used for microorganisms such
as yeast. Glucose is partly broken down into ethanol or lactic
acid with the release of a small amount of energy


Fertilisation - THE CORRECT ANSWER-The joining of of the haploid
male and female gametes to form a new diploid individual


Gametes - THE CORRECT ANSWER-The haploid sex cell which contain
only one set of chromosomes. Male gametes include sperm and
pollen, female gametes include ova and ovules


Genetically modified organism - THE CORRECT ANSWER-Organisms
which have had DNA from a different species or a different
individual inserted in their genome


Genotype - THE CORRECT ANSWER-The genetic makeup of an
organism concerning the alleles of a particular gene. e.g TT, Tt,
tt


Global warming - THE CORRECT ANSWER-An increase in the
temperature at the surface of the earth due to green house gases
in the atmosphere trapping infrared radiation from the surface
