BIOLOGICAL DRAWINGS FROM MICROSCOPE SLIDES A comparative analysis
ELODEA LEAVES showing one or more hook cells on the edge of a leaf
low A cell arrangement OK but: proportions are off; tip of hook cell inaccurate, chloroplasts too big for cell … overall, too stylised for a drawing
N proportions way off; hook cell curved on wrong side; inconsistent representation of the cell wall
low M angle between leaf and hook cell is a bit too wide
A tip of hook cell doesn’t show its main special feature i.e. thick cell wall
high A cells a bit wide and too rounded at ends
N cell shapes wrong cells don’t look like part of a leaf interlocking of cells doesn’t match slide hook tip has not been thickened! chloroplasts drawn too large
A cell outlines too wavy; tip of hook cell inaccurate; chloroplasts drawn carelessly (have hair!)
A cells too far apart; shapes don’t interlock well
M immediately obvious which cells have been drawn
A cell shapes don’t interlock enough chloroplasts too big for cells cell wall thickness too variable
LEAF TEARS showing a stoma and guard cells surrounded by epidermal cells
some shape mismatch sketchy lines chloroplasts open! A
M could have shown: membranes of plasmolysing cells, thick edges of guard cells around the stoma opening
M shapes, proportions and spacing excellent
A guard cells drawn far too large and cell shapes don’t match
N significant mismatch of shapes and sizes
M could have shown membranes of plasmolysing cells air bubble!
M obvious from shapes which cells have been drawn
A cell junctions misplaced shapes don’t match the specimen very well
specimen is clearly well understood by person drawing M
N epidermal cell shapes a poor match and way too small compared to guard cells; not enough cells drawn
M accurate, but ideally should show a couple more complete cells
A nuclei and shapes don’t match specimen very well
N mismatch of shapes and proportions; cells being “scalloped” off first cells; two cells drawn as one?
A guard cells way too small
A cells too angular guard cells too small
M clear match
A cell junctions don’t match and proportions are off
A cell proportions off: three need to be narrower for M
M clear match to specimen
M starts of walls of surrounding cells show that these cells are part of a larger piece of tissue
A guard cells drawn too elongated epidermal cell shapes do not match specimen well
SPIROGYRA a unicellular organism that lives in threads with other Spirogyra
…but why would you even try to draw something this hard? M
Scale & Proportion Too Big, Too Small, Just Right!
