Exercise 1.7 - Measurement of Cell Organelles
Figure 1.9 Photo of various cells showing organelles
- Prepared Slides of the following:
- Onion Root Tip
- Dicot Leaf x.s.
- Each of the slides presents a representative cell, with
various organelles of particular interest. Figure 1.9 gives
a sample of some of these cell types. Observe each slide,
and make a drawing of each cell and its representative
Each drawing should meet the following guidelines:
- All drawings must be completed in pencil. A #3 pencil
is preferred since it will not smudge as readily as the
standard #2. Colored pencils are optional. Ink is
- Each drawing must be a minimum of 4" x 5" in size.
Smaller drawings will not demonstrate sufficient detail,
while much larger drawings require excessive time to fill in
- Drawings should be completed during the lab period and
where applicable, on any forms provided.
- All labels should be added and appropriate indications
of size should be made. Size is best indicated by including
a ruler bar at the bottom of the drawing, drawn to scale and
with the dimensions added.
- Measure the appropriate dimensions of all structures.
Label the drawings, and indicate the magnification used to
- On each drawing, place a line (bar) to indicate a length
of 10 microns.
