Plant Dissection
• Examine the plant you’ve been given.• Sketch it and use various resources to label
your sketch.

Tissues
▪Meristematic Tissue▸Where cell division occurs▸Creates all new cells and
tissues▸Differentiation -
specialization of cells into certain tissues with certain functions

Dermal TissueThe Outer Layers
▪Waxy Cuticle▸Protects against
damage, water loss and infections▪Hairs▸Discourage
herbivores▪Chemicals▸Irritants
▪Epidermis▸Outer layer of cells▸Becomes bark in
woody plants

Ground TissueThe Filler▪Internal cells
▪Different cell types with different functions e.g. storage, support, photosynthesis
▪E.g. Flesh of fruits and vegetableshttp://www.greentales.com/files/pear.jpg

Vascular TissueTransport
▪Xylem▸Conducts water
and minerals from roots to shoots▸Thick walled cells▸Work even when
dead▪Phloem▸Transports sugar
and other solutes from shoots to roots▸Thin walled cells▸Living

Biological Drawing GuidelinesKeep the following guidelines in mind when completing a formal biological drawing of an object you viewunder the microscope:
1. Use pencil (preferably soft lead that will not smudge).
2. Please print.
3. Please use unlined white 8 1/2” x 11” paper or lab drawing paper.
4. The drawing should be titled at the bottom with the figure # and appropriate title. Below that you record themagnification.
5. The drawing should be approximately1/2 of the page.
6. Keep the drawing to the left of thecenter.
7. Labels are to line up on the right handside of the page.-- use a ruler to draw lines from theobject to the label-- lines should never cross over top ofeach other–all labels should line up vertically
8. Do not use plural labels to point to asingle object. Keep the labelsconsistent.
9. The drawing should be an outline ofwhat you see. Do not include additionalstructures just because you think youshould see them.
10. Do not shade. All lines should besolid and complete. You may stipple toshow different regions.
11.When using the scientific name of an organism remember that the genus or first part of a scientific name isalways capitalized. The species or second part of a scientific name is not. A scientific name is usually italicizedas well.
FOR EXAMPLE: Canis familiaris is the genus and species name for a dog.

Do not use plural labels to point to a single object. Keep the labels consistent.▪9. The drawing should be an outline of what you see. Do not include additional structures just because you think you should see them.
▪10. Do not shade. All lines should be solid and complete. You may stipple to show different regions.
