B3 Student checklist Living and growing
Tick () column: A when you have covered the statement
in class.
Tick () column B if you need to do more work on it.
In your revision for your end-of-block test or final
examinations, concentrate most time on those statements
not ticked.
Tick () column C when you are confident you can
answer any questions on it.
Statements in bold can only appear on the Higher tier
paper.
I can:
1 Identify parts of the cell and describe their function
State that the coded information is carried in the form of DNA in genes
on chromosomes
State that one gene codes for one protein and that most have their effect
by the production of enzymes
Describe the biological importance of enzymes and their specificity for
the substrate.
Interpret data on DNA fingerprinting
Describe the structure and copying of DNA and its role in protein
synthesis
State that some amino acids can be changed into others and that
proteins have particular sequences of amino acids that determine
their shape and function
Use a microscope
Prepare a temporary slide
2
Describe diffusion and its effect on the movement of molecules into and
out of cells
Describe the movement of substances such as digested food and gases
into the blood stream and across the placenta in terms of diffusion
Describe the movement of gases into and out of leaves and explain their
loss of water in terms of diffusion
Explain the effects of three factors on diffusion rates and relate these
to gaseous exchange and food absorption.
Explain the diffusion of transmitter substances across synapses
Examine slides with a microscope at high power
3
Describe the structure and operation of the heart and how it and the blood
vessels transport substances around the body.
Explain that cholesterol build-up in arteries is linked to diet and can
restrict blood flow
Describe the problems associated with mechanical and biological heart
replacements
Explain the advantage of a double circulatory system
Explain the adaptations of arteries, veins and capillaries to their
functions.
Describe advantages and disadvantages of pacemakers and valve
replacement over heart transplants
A
B
C
Can perform a simple dissection
4
Explain the advantages of being multicellular
Explain that cells need to be replaced by mitosis, which maintains the
diploid number of chromosomes.
Explain the basic points of meiosis and mitosis
State that sexual reproduction involves haploid gametes combining to
form a diploid zygote
State that gametes are produced by meiosis, which introduces variation.
Explain how sperm and egg structure are adapted to their function
5
Identify and describe the importance of chloroplasts, vacuole and cell
wall in a plant cell.
Describe how to make a stained slide of an onion cell.
Compare animal and plant cells.
Describe the differences between animal and plant growth.
Describe the main phases of human growth, explain and manipulate data
on differential growth rates.
State that undifferentiated (stem) cells can develop into different cells,
tissues and organs.
Discuss issues arising from stem cell research.
6
Discuss issues arising from stem cell research and state the photo and
geotropic responses of shoot and root.
Describe an experiment to demonstrate positive phototropic response in
shoots.
State that auxins move in solution and are involved in phototropism and
geotropism and relate the action of plant hormones to their commercial
uses.
Interpret data from phototropic experiments and explain how auxin
causes shoot curvature.
7
Explain that mutations are a change in the DNA base sequence, how they
are caused and that, usually harmful, they may be beneficial.
Describe the process of selective breeding and explain how this can
contribute to improved agricultural yields.
Define, with examples, genetic engineering/modification and explain
some of the advantages and risks.
Describe the principles of genetic engineering and discuss the moral
and ethical issues involved
8
Describe cloning technique in cows; recall advantages of cloning and
recognise that there are ethical dilemmas.
Describe asexual reproduction in plants and the advantages and
disadvantages associated with commercial cloning.
Describe the cloning techniques used to produce Dolly the sheep and
discuss the benefits and risks in cloning and the implications and
dilemmas involved.
Describe cloning by tissue culture and explain why cloning plants is
easier than cloning animals.
Can carry out aseptic techniques
