AQA Biology Triple Paper 1
Exam Questions and Answers
100% PASS
What is cell differentiation?—ANSWER-the process by which unspecialized
cells develop into their mature forms and functions
What is a eukaryotic cell?—ANSWER-Cell with a nucleus and membrane
bound organelles
What is a prokaryotic cell?—ANSWER-cell that does not have a nucleus or
membrane bound organelles
What are the Differences and similarities between Prokaryotic and
Eukaryotic cells—ANSWER-Eukaryotic contain a nucleus and Prokaryotic
dont
Eukaryotic= 10-100hm (micro)
Prokaryotic = 0.1 - 10 hm (micro)
what does the word centi mean?—ANSWER-"centi" means 1/100th (of a
metre) so 1m = 100 cm
1 x 10^-2 m
,What does the word milli mean?—ANSWER-It means 1/1000th ( of a metre)
so 1cm = 10mm
1 x 10^-3 m
What does the word micro mean?—ANSWER-It mean 1 millionth (of a metre)
1 hm = 1 x 10^-6 m
used to measure cells
What does the word nano mean?—ANSWER-It means 1 000 000 000 th (of a
metre )
1nm= 1 x 10^-9
used to measure proteins in cells such a hemoglobin
What is the Order of Magnitude?—ANSWER-A way of comparing sizes of
objects
EG. each order of magnitude is increased by x10
x10 = 1 O of M x100 = 2 O of M
ANIMAL AND PLANT: What is the function of the nucleus?—ANSWER-
contains the cell's genetic material (DNA)
ANIMAL AND PLANT :What is the function of the Cytoplasm?—ANSWER-
Where chemical reactions take place
ANIMAL AND PLANT: What is the function of the mitochondria?—ANSWER-
Where cellular Aerobic respiration takes place

, ANIMAL AND PLANT: What is the function of the cell membrane?—
ANSWER-The cell membrane regulates what enters and leaves the cell and
also protects and supports the cell.
ANIMAL AND PLANT: What is the function of Ribosomes?—ANSWER-The
site of protein synthesis, where new proteins are made.
PLANT: what is the function of chloroplasts?—ANSWER-Contain chlorophyll
, allows photosynthesis.
PLANT: what is the function of the cell wall?—ANSWER-Made from cellulose,
strengthens the cell
PLANT: what is the function of the Vacuole?—ANSWER-Filled with cell sap.
Help keeps the cell in its shape.
What is differentiation?—ANSWER-The process by which a cell changes to
become specialised for its job
What are examples of unspecialised cells?—ANSWER-Stem cells
Animal: What are sperm cells and how are they specialised?/adapted?—
ANSWER--Sperm cells aid in reproduction, they pass on the fathers DNA so
it can pair with mother DNA in the ovum
-Sperm contains half the amount of chromosomes in nucleus.
- They have a long tail that rotates which allows it to swim
- contain many mitochondria so provides alot of energy
- the head contains enzymes to digest the the outer layer of ovum and allow
the sperm to enter
