Plant Structures Review
Test will be 2 parts. Friday = written
Monday = lab
Lab test will be actual slides or plants or leaves or photos and ask you to identify things we looked at in notes
or in labs. It will include fern spores, gametophyes (both kinds) and sporophytes, be sure you can tell what
each is from actually looking through a microscope or from a picture. It will include leaf stem and root
microscope slides, be able to tell what plant part you are looking at and identify the tissue at the pointer. For
example the pointer could point to epidermis or xylem or a guard cell. Be able to identify the stomata from
our nail polish slides and know what it means if there are lots or few stomata. Be able to tell me what type of
leaf margin and venation a leaf has and if it is a compound or simple leaf. Be able to identify types of roots
and the parts of a moss sporophyte. Study your drawings made in class 
