Dr. Whipple
Week 25th
March 6th – 10th
This week we will…
• Finish our oral presentations and this unit on organelles
• Review prokaryotes versus eukaryotes, organelles, and ATP production
• Have an in-class, open notebook test on Monday, March 13th
Homework:
• Spend (at most) 15 minutes each day reviewing prokaryotes vs. eukaryotes cell and
organelle (and tissue) functions, similarities, and differences.
Specifically this includes:
§ Read (or re-read) the handout I gave you on “cell types and tissues”
§ read over your notes and make sure they are up-to-date
§ review your notes from everyone’s presentations
§ re-watch posted videos
§ flip through the animal vs. plant cell powerpoint
§ answer the questions below (we will also cover these in class on
Monday)
§ write down any questions you have and bring them to class to discuss
– this is due by Thursday March 9th
A few study topics/questions to help gauge your understanding:
• What organelles are present in plant cells that are NOT present in animal cells?
• How does the cell structure/shape differ in plant cells versus animal cells?
• Give two differences between an angiosperm and a gymnosperm?
• Why would it be incorrect to ask you what the xylem and phloem do in mosses?
• The plant kingdom is broken into 4 groups or classifications, what basic features are
these groups based upon?
• Describe the general function of the endoplasmic reticulum, golgi apparatus,
mitochondria, nucleus, chloroplasts (thylakoid and chlorophyll), and central vacuole.
• What do eukaryotic and prokaryotic cells use for energy? What (yummy) molecule is
broken down to make it?
• What is cellular respiration? Where does it occur? What are the general reactants and
products of cellular respiration? (Ie. what does the cell need to go through cellular
respiration and what is the net result of completing cellular respiration?) Where do
the reactants come from…how/what organism makes the key “ingredient”?
• Give 3 differences between monocots and dicots.
• Give 3 examples of monocot plants and three dicot plants.
• Be able to identify a cross section of a dicot versus monocot stem AND root. (ie.
How is the organization of the vascular bundle different in each class? How do the
root and stem organization differ?)

What is the difference between a taproot and a primary root? Which type does a
monocot have?
In general, how do the leaf veins of a dicot differ from a monocot?
What is the job of xylem and phloem? Which transports water and which moves
sugar? Which is made of living cells and which of dead?
What organelle modifies proteins but trimming them and adding sugar residues so as
to give them their correct final shape? What does their shape matter so much?
If the plant does not have much water due to a drought, would the stomata likely be
open or closed? Would that mean the guard cells are full or flaccid? When the stoma
is open, what molecules (other than water) are let in and out of the leaf? Where are
the stomata located?
Where are new, immature…or “baby” proteins (polypeptides) made? On what type
of protein and in what organelle?
What type of tissue protects the soft young plant and covers it with a waxy layer?
(hint – this is a very thin layer of cells)
Where does photosynthesis occur? (what specific part of what organelle?) What does
the plant need in order to carry out photosynthesis and what does it make? (Ie. What
are the general products and the reactants of photosynthesis?)
What type of plant tissue has very small vacuoles and would be undergoing a large
amount of mitosis?
What are two types of meristem and where are they located?
What is parenchyma? How does chlorenchyma differ from parenchyma?
What type of tissue contains chloroplasts, has large central vacuoles, helps with gas
exchange (due to small spaces between them), and are located in the mesophyll of
leaves and stems?
What is a trichome? Give two examples and a function of each.
The outer most layer of stem and roots of woody plants is made of what type of
tissue? What is the common name for it? What are some common uses of this type of
tough tissue?
