ANSWER SHEET
This exercise is designed to allow the students to visualize some real life cells and
there functions. Pass facilitators to ask what the functions are of the cells, do
not give answers to students and if necessary there are always textbooks!
1. ONION CELLS, FUNCTION: The cell wall functions to support and protect the cell.
Plants have cell walls composed of cellulose; fungi have walls composed of chitin. The cell
walls of these onion skin cells can be easily seen. What is the cell wall composed of?
2. RED BLOOD CELLS, FUNCTION: Red blood cells contain the protein haemoglobin
which carries oxygen around your body
3. NERVE CELLS, FUNCTION: A neuron is the fundamental unit of the nervous system,
having structure and properties that allow it to conduct signals by taking advantage of the
electrical charge across its cell membrane. Q-What role does the synapse have?, Explain
the resting potential?, What triggers the action potential? Compare the central nervous
system and the Peripheral nervous system?
4. WHITE BLOOD CELLS, FUNCTION: This cell functions in defending the body against
infections and cancer cells. The white blood cells have a variety of ways by which they can
attack. Some will produce protective antibodies that will overpower the germ. Others will
surround and devour the bacteria.
EUKARYOTIC CELL DIAGRAMS
Students will require some mental recall in this task to name the cell
structures in the following cells. It is better if students don’t use their
textbooks to label the diagram but attempt to fill in as much as they can
by memory and discussion to others on their table. Facilitators can decide
whether they want to include structural list or cut them off and get
students to memorise the organelles entirely on their own. Discuss some
of the functions of the following:
Mitochondrion
Central vacuole
Lysosome
Chloroplast
Plasmodesma/ta
Ribosomes
Golgi apparatus/complex
Cytoskeleton
Nucleus
What structures are in animal cells and not in plant cells/ vice versa?
Animal cell
Plant cell
