Lesson 7: Plant and Animal Cells
Reflecting on What You’ve Done
A.
Based on the alga Spirogyra that you observed, would you consider Spirogyra to be more plantlike or animal-like? Explain your answer.
PLANT! It has chloroplasts AND a cell wall.
Animal cells do not have these.
B. Why do you think the bulb of the onion plant (the part you eat!) is so big? What function does it
serve for the plant?
NOTE: The bulb of the onion holds all the water for the plant.
C. What happened to the Elodea leaf cells when they were soaked in salt solution? How do you
think this relates to what happens when you eat salty foods?
NOTE: The cytoplasm was “dried” up, shrinking the
cell membrane away from the cell wall.
(give yourself an example in your own words)
(for people at home…) Think about what you have to do if you eat a lot of
salty foods all at once…you have to drink something! That’s because you’ve
dehydrated your cells in your mouth.

Lesson 7: Plant and Animal Cells
Use the Venn diagram to show the organelles that you observed in cells from the onion bulb, Elodea
leaves and those you know about animal cells.
Elodea Leaf Cell
Cell wall
1 Large vacuole
D.
Cytoplasm
nucleus
cell membrane
Onion Leaf Cell
chloroplasts
(secondary
organelles)
No
chloroplasts
Vacuole- Storage container in a
cell. Used for storing water,
waste, minerals, etc.
No cell wall
multiple small vacuoles
Animal Cell
E. If animal cells do not have cell walls, what gives animals such as mammals shape and support?
Bones and muscles.
F. Give one example from among the cells you observed in this lesson of how the size and shape of
the cell is suited for its particular function.
NOTE: Focus on features…
Elodea- chloroplasts give elodea its energy
Onion leaf cell- so large so that it can hold water
