Cell membrane
Which structure is the outermost layer of a plant cell and is different from animal cells?
The cell wall

a. put each slide under a microscope
b. hold up to a lamp
c. weigh them
d. add pH indicator
a. put each slide under a microscope
Which type of cell has a cell wall and chloroplasts: plant cells or animal cells?
Plant cells.
Which organelle is commonly called the "control center" of the cell and contains genetic information?
The nucleus
Which organelle makes food for the plant cell and is usually green?
The chloroplast
Which statement is true:
a. antibiotics kill only bad bacteria
b. some bacteria can be both helpful and harmful
c. people should avoid all bacteria with stronger cleaners
d. bacteria with no known use should be eliminated?
b. some bacteria can be both helpful and harmful
Nathan wants to investigate the claim (idea) "all living things are made of cells." Which tool should he use to look for cells in living and nonliving things? (Hint: what type of tool can he use to see things that cannot be seen with the naked eye?)
A microscope
I am the powerhouse of the cell.
What organelle am I?
mitochondria
Select three structures that should be included when drawing an animal cell model (pick three):
1. nucleus
2. cell wall
3. cytoplasm
4. chloroplast
5. cell membrane.
What is the job/function of the cytoplasm?
It surrounds and holds the organelles together, it helps dissolve cell waste
Which statements are true about the nucleus of an animal cell? (Pick three.)
a. it controls release of wastes
b. it controls cell growth
c. it makes energy
d. it contains genetic information
e. it is largest and most visible organelle
f. it sorts and packages proteins.
b, d, e
When preparing to use a compound microscope, name two safe classroom steps students should do before putting a slide on the stage. (Choose 2)
a. Wash hands
b. carry the microscope with two hands
c. unplug the microscope
d. begin looking at the slides
a, b
Is the bacteria in yogurt good or bad? Why?
Good, because it helps your gut
Which statement about the nucleus is correct?
a. it controls cell growth
b. it makes all the energy for the cell
c. it sorts and packages proteins
d. it controls the release of wastes.
a. it controls cell growth
A student labeled cell wall, cytoplasm, nucleus, and chloroplasts. Which feature best explains how the cell wall is different from the other parts?
It is located on the outside of the cell. Gives plants their structure
Which of the following is NOT an example of beneficial microorganisms:
a. microbes used to produce insulin
b. microbes used to treat wastewater
c. probiotics helping digestion
d. food containing microbes that can transfer to humans if not cooked properly
d. food containing microbes that can transfer to humans if not cooked properly
Why is it helpful to use different magnification levels when looking at cells? (Hint, what is the difference in the image when you zoom in 10x, 40x, and 100x)
Different magnifications help scientists see both the whole cell and tiny details. Low power shows the big picture, and high power shows small parts clearly.
I can be found in both plant and animal cells.
I also store things.
What am I?
vacuole
Explain why animal cells do not have chloroplasts and cell walls, using one or two clear sentences
Example: Plant cells have chloroplasts for photosynthesis and a rigid cell wall; animal cells do not, because animals get energy differently and need flexible cell membranes.
Provide two ways plant cells differ from animal cells, using correct organelle names. (Two clear bullet points; 1 sentences each.)
(1) Plant cells have a cell wall; animal cells do not. (2) Plant cells contain chloroplasts; animal cells do not.
Explain how some microorganisms can be beneficial to plants in this scenario:
- Some yeasts help plants to rapidly divide their cells in their roots. Which argument supports the claim that some yeasts are beneficial to plants?
- Plants can use more sunlight with large roots
- Plants can make bigger flowers with large roots
- Plants won't need much nutrients with large roots
- Plants can take in more water with large roots
- Plants can take in more water with large roots
Describe what you would expect to see under a microscope when comparing an animal cell slide to a plant cell slide.
plant cells show cell wall and chloroplasts and often a large central vacuole; animal cells lack cell wall and chloroplasts and are rounder.
Double Jeopardy:
Name ALL of the organelles in a plant OR animal cell.
