Course Introduction:
This course is designed as an introduction to the cellular structure of the vascular
plants. We will investigate plant cell, tissue, and organ structure, concentrating on the
seed plants (gymnosperms and angiosperms), and will be working mostly at the light
microscopy level. We will integrate the internal tissue organization (anatomy, or
histology) with the outer form (morphology) and will give an overview of plant
reproduction and development. The laboratory and lecture will be intertwined, with the
laboratory providing examples that illustrate the conceptual topics covered in the
lecture.
Course Materials:
There is not currently a suitable textbook for this course, but we will provide readings
and links to online resources, as well as review materials prior to the exams. A general
botany textbook may be helpful, especially for students who are less familiar with
terminology and plants in general. We have designed the plant anatomy lab manual
especially for this course.
Each lab will be available on Blackboard each week for that particular lab, and the TA
will also provide paper copies of the labs for you to put in your lab notebooks. All
resources for the course, including the syllabus and laboratory manual, readings, review
sheets and images, links to useful websites, and examples of previous years' student
projects, will be posted on Blackboard. Lecture exams will be drawn from lecture notes,
the laboratory notebook and other readings; laboratory exams will be prepared from
materials covered in the lab.
Student Expectations:
Please attend all lectures and laboratories. This course is not a conceptually difficult
one, but it does contain a lot of terminology and ideas and structures that build on one
another and you will do best to come and participate. We teach this course the old
fashioned way, with everyone taking notes and drawing line diagrams together, rather
than with PowerPoint lectures, because this it the best way to focus your attention on
this type of topic, so it is important to come to class. Something magical happens
between brain and hand when you draw what you are seeing and helps you learn at a
level much better than viewing photographs and powerpoints alone.
There will be additional information about the lab in another handout. We expect
you to complete the laboratory exercises in the lab manual each week and will
pick them up a couple times to make sure you are understanding the information.
The reason for drawing diagrams and labeling material is to learn the material and to
convey to us that you have seen what we want you to see. If you miss a lab there will be
opportunities to a limited extent to look at material from a previous week. We encourage
you to work together in the lab and endeavor to have a congenial atmosphere that is
conducive to learning.
Assessment:
We will have one lecture midterm and a non-comprehensive final (essentially a
second midterm), a laboratory practical midterm and final. There will be quizzes
during the labs, so be sure and read the lab exercise before coming to class. This
course will assess your knowledge of material equally between laboratory and lecture.
Grading (based on 24 previous years of teaching this course) is as follows: This course
will be graded on an A, B, C, D, E scale (no +’s or -‘s) with consideration for borderline
grades at the end of the semester.

Lab conduct:
The lab period is from 1:00-4:15 pm on Wednesdays. Plan to be here for the entire
lab time. The best way to assure a good grade in this class is to take the labs
seriously!
Please don’t make dentist appointments or other plans during this time. You don’t have
to sit there the entire time, you can take breaks, but the labs will vary, we will have
quizzes, do group activities, maybe even sometimes lecture, during the lab time. Often
you will be working at your own pace and you are welcome and encouraged to get up,
take a break, move around and come back. This is much better than trying to rush
through the lab so you can leave early---that will not work in this course, so please
don't plan a quick getaway . While in lab, please be respectful toward everyone, and
the equipment, and facilities. Please remember to leave your area clean and return
materials to their proper place. Please don't eat in the lab, you can step outside to have
a snack.
ASU STATEMENTS
DISABILITY: " If you have a disability which requires accommodation, please inform the
instructor as soon as possible (not at test time or the end of the semester). If your
disability is a learning disability, please have your counselor contact the instructor to
discuss accommodation"
FIRE DRILL PROCEDURE:“In the event of a fire alarm signal students will exit the
building in a quick and orderly manner through the nearest hallway exit. Learn the floor
plan and exits of this building. Do not use elevators. Crawl on the floor if you encounter
heavy smoke. Assist disabled persons and others if possible without endangering your
own life. Assemble for a head count at the front of LSE, between the Social Sciences
building and Hayden Library."
ACADEMIC DISHONESTY!
“In the “Student Academic Integrity Policy” manual, ASU defines “’Plagiarism” [as] using
another's words, ideas, materials or work without properly acknowledging and
documenting the source. Students are responsible for knowing the rules governing the
use of another's work or materials and for acknowledging and documenting the source
appropriately.” You can find this definition at:

Academic dishonesty, including inappropriate collaboration, will not be tolerated. There
are severe sanctions for cheating, plagiarizing and any other form of dishonesty”.
