3. B1 REVISION – CHAPTER 1 – Cell Biology- mark scheme
What do plant cells have that animal cells do not?
What is the function of:
Nucleus – controls the activities of the cell and contains genetic material
Mitochondria - aerobic respiration – energy is released
Ribosomes - protein synthesis
Chloroplasts - structure containing chlorophyll
Cell Wall - strengthens and supports the cell
Use a diagram and words to describe a specialised cell
Any specialised animal or plant cell with adaptation and function of that adaptation.
e.g. sperm cell – enzymes in head to penetrate the egg, many mitochondria for energy release for swimming to the egg, tail for movement.
Muscle cell – many mitochondria to provide energy for muscle contraction, protein filaments which slide over each other to produce muscle contraction.
sketch and label a plant and an animal cell; .
Draw and label a diagram of a prokaryote e.g. Bacteria
KEY WORDS:
Bacteria
Nucleus
DNA
Cytoplasm
Plasmid
Cell membrane
Mitochondria
Ribosome
Chloroplast
Vacuole
Specialised
ASSESSMENT:
List the main differences between a prokaryotic and eukaryotic cell
Prokaryotic – much smaller, No nucleus , DNA not enclosed in nucleus, may have plasmids

4. Trilogy – Biology – CHAPTER 1 – Cell Biology
How is total magnification calculated?
Total magnification = magn eyepiece x mag objective lense
What is the equation for:
Aerobic respiration?
Glucose + Oxygen Carbon dioxide + Water (energy released)
Or correct symbol equation
Anaerobic respiration?
Glucose Lactic acid (energy released)
Fermentation?
Glucose ethanol + carbon dioxide (energy released)
Draw and label a diagram of mitosis
How is the magnification of a an image under a microscope calculated?
Mag image = size of image/size real object
What is a TEM? Transmission electron microscope
What is a SEM? Scanning electron microscope
What is the link between mitosis and cancer?
A cancerous cell is a cell dividing by mitosis uncontrollably. The extra cell form tumours
What are the characteristics of a
Benign tumour? Slow growing, often have capsule around them making them relatively easy to remove , rarely spread to other areas of the body, not cancerous
Malignant tumour?
Grow faster than benign tumours, can spread t other body tissues, can form secondary tumours .
What is a stem cell?
Unspecialised cell that can develop into a specialised cell
What are the potential uses of stem cells?
Medical uses e.g.
Faulty red blood cells, diabetes, spinal injuries
Write down one ethical objection to stem cell research?
Embryo is destroyed – possible life
What is therapeutic cloning?
Process of creating stem cells with the same genes as the patient, through nuclear transfer
