This exam is made up of fill-in-the blank, identification questions. Spelling is very important for these
questions. Be careful with your typing!
Not every labelled structure in the picture being used may be associated with the question. So, do
not be surprised if a figure has 4 letters and I only ask you to identify 1 of them
There are multiple versions of this exam and every student gets a unique set of questions.
This lab exam is not open book
All of the exam questions are shown at once – scroll up and down and answer the questions in
whatever order you like.
You can flag the questions you want to go back to by clicking the flag by the question. The flag will

At any point during the exam, you can view a summary of your exam. Questions you’ve answered
will be faded out and identified by a checkmark icon, while unanswered questions will be bolded and
identified by a question mark icon.
You’ll also see a timer showing your progress on the exam. The timer will show the running time and
counts down until time expires.

Don’t stress out – Canvas saves all answers automatically every 7 (seven) seconds, in case
there is a problem, for example with your Internet connection or your computer and you get kicked
out. You can change your answer at any time and it will re-save when you select it. Upon
submission, Canvas re-saves everything that is on the form.
Grading
These identification lab questions need to be graded manually by me. This means that the score you will
receive upon submitting the exam will probably not be your final grade. I will review your exam and make
corrections to your score if possible. Final results will be posted into your grade book and an
announcement will be sent telling you that the exam has been graded. I will convert your lab exam grade
to 25 points and post that into your grade book as well. Comments may be added to your exam in the
comment box.

Doing the Exam
This exam is 3 hours long and you will have only one attempt at this exam.
It includes 5 bonus points – so your score you receive after you are done this exam will
actually be out of 70 (not 75)
To begin the exam, click the Take the Quiz/Exam button. You may resume the exam by pressing
the Resume Quiz/Exam button.
This exam may be made up of multiple-choice, true/false, matching, fill-in-the-blank and short answer
questions. There are multiple versions of this exam and every student gets a unique set of
questions.
This exam is open notes. However, the exam requires that you take it by yourself. You are not
allowed to consult with a classmate, or anyone else while you take this exam. I will compare
your short answer questions to other students and to websites that are known to have copies of old
exams. If I find any similarity between your answers and another students, or with a website – I will
give you “0” for that question and possibly for the entire exam. Do not waste your time trying to
cheat, you will run out of time.
All of the exam questions are shown at once – scroll up and down and answer the questions in
whatever order you like.
You can flag the questions you want to go back to by clicking the flag by the question. The flag will
change color to yellow to remind you to finish the question. The yellow flag will also appear in the

out. You can change your answer at any time and it will re-save when you select it. Upon
submission, Canvas re-saves everything that is on the form.
Grading
Short-answer exam questions will be graded manually by me. I will also review the remaining exam
questions. Results will be posted into your grade book and an announcement will be sent telling you that
the exam has been graded. I will convert your exam grade to 100 points and post that into your grade
book as well. Comments may be added to your exam in the comment box.
Bonus Questions
Most lecture exams will come with bonus questions. The total score given by Canvas will include these
bonus points. I will adjust your exam score to account for these bonus questions. For example, Canvas
will grade an exam out of 80 points. However, if 5 of those points are bonus, the exam is actually out of
75 points and I will calculate your final exam score taking that into account.
Questions about an Exam
If you have any questions about the exam, or think that an exam question was graded incorrectly, you
may email me. Please give me the specific question(s) that you are concerned about and I will review it.
If a mistake was made in a question, the question will be regraded and a new exam score will be posted.
I will correct the score in your grade book.

Clarify Question
• What is the key concept addressed by the question?
o The question is asking whether you can identify the sequence in
which land plants evolved.
• What type of thinking is required?
o The question requires you to apply your understanding of these
taxa to place them from oldest to youngest in age.
• What key words does the question contain and what do they mean?
o Prokaryotes: organisms whose cells do not possess a nucleus or
membrane-bound organelles; Bacteria and Archaea
o Protists: eukaryotic organisms that are not plants, animals, or
fungi
o Streptophytes: a clade consisting of land plants and their closest
non-plant relatives, the streptophyte algae
o Angiosperms: flowering plants
Gather Content
• What do you already know about these groups?
o To answer this correctly, you need to have a good understanding
of the characteristics of these groups and/or their evolutionary
relationships. You also need a good grasp of the vocabulary
associated with these groups (e.g., bacteria and prokaryotes are
essentially synonymous for this question).
Consider Possibilities
• So what do you know about these groups?
o You should be able to identify that prokaryotes/bacteria (present
in all five answer choices) should be the first group, since they
existed long before any of the other groups. You should be able to
identify that angiosperms (also present in all five answer choices) is
the most recent taxon of plants to evolve.
Choose Answer
• Given what you now know, what information and/or problem solving
approach is most likely to produce the correct answer?
o If you have prokaryotes/bacteria and angiosperm in the correct
positions, you now have to compare two answer choices that have
the same five additional groups. Should streptophytes come before or
after mosses? Since mosses are plants and streptophytes are
photosynthetic algae, streptophytes should come before mosses. You
could also use the placement of ferns and conifers to help since
could also use the placement of ferns and conifers to help, since
conifers are more similar to angiosperms.
Reflect on Process
• Did your problem-solving process lead you to the correct answer? If
not, where did the process break down or lead you astray? How can
you revise your approach to produce a more desirable result?
o Did you have a clear idea of what types of organisms all these
terms described? If not, it would be difficult to put them in order.
o Did you remember which taxa were plants and which were not?
o Did you remember the order of evolution of plants based on
presence of vascular tissue, motile sperm, and reproductive
structures?

The route followed by a sperm from production to fertilization in a
flowering plant is:
A sperm cell, enclosed in a pollen grain with another sperm, is produced in
the filament
It is transported to a stigma where it passes through a pollen tube that
grows down the style to the ovary
The pollen grain enters the ovule and joins with the egg cell.
A sperm cell is produced in the anther
It is transported to a stigma where it becomes enclosed along with another
sperm cell into a pollen grain
The pollen grain grows down the style to the ovary
It enters the ovule and joins with the egg cell.
A pollen grain is produced in the pistil, which explosively ejects it into the
air
The pollen grain is transported to a stigma where it forms two sperm cells.
One of the sperm cells passes through a pollen tube that grows down the
style to the ovary
The sperm enters the ovule and joins with the egg cell.
A pollen grain is produced in the anther
It is transported to a stigma where it produces two sperm cells that pass
through a pollen tube that grows down the style to the ovary.
One of the sperm cells enters the ovule and joins with the egg cell.
A sperm cell, enclosed in a pollen grain with another sperm, is produced in
the anther.
The pollen is transported to the stigma of the flower, where the two sperm
travel down the pollen tube that is growing down the style to the ovary,
The sperm enters the ovule via the micropyle and fertilization takes place
