Review Sheet for LE MYP SUM 2.1b
Label the plant, animal, and bacterial cell.
Label whether each cell is PROKARYOTIC
(old school with no membrane-bound
organelles) or EUKARYOTIC (more recently
evolved and more complex with membranebound organelles).
Label each of the lettered and numbered structures in the diagram.
What is the name of the structures that carry out the life functions (a.k.a. metabolic processes)
within cells? ______________________________________________
On the plant cell, add in labels for the cell membrane and the cell wall.
Fill in the chart below:

2. Cell Membrane
Go and find that binder page we did where we diagrammed the cell membrane. Based on your
diagram, record some facts about the cell membrane.

s-l-o-w…
Neurotransmitters like
dopamine
Secreted from 1 neuron to the
other through the synapse
Hormones like insulin or
testosterone
Secreted from endocrine
glands (e.g. pancreas) into
bloodstream
Label the parts of the neuron below. Draw in a second neuron for the first neuron to communicate with. Draw
in some chemical messengers (a.k.a. neurotransmitters) being secreted at the axon terminals of the first
neuron. Finally, describe how the impulse travels (i.e. where is it electrical? Where is it chemical?)
Explain the process occurring in this diagram using
the following words: axon terminal, cell
membrane, chemical messenger molecule,
dendrites, receptor molecules, specificity.
Explain the process occurring in this diagram.
