1
If you can only see one organelle in a cell, it is probably the:
nucleus
chloroplast
endoplasmic reticulum
mitochondria
2
How do the smoothER and roughER differ?
all of the above
One has ribosomes attached
SmoothER makes lipids
RoughER makes proteins
3
The main difference between prokaryotes and eukaryotes is
the presence of DNA
the presence of ribosomes
the presence of a cell wall
the presence of organelles and a nucleus
4
Viruses are nonliving because they do not:
don't do any of these 3 things
take in or release energy
grow and respond to stimuli
reproduce on their own
5
This unicellular bacteria/organism MUST carry out all of life's activities. It is a:
eukaryote
prokaryote
6
Viruses are considered nonliving because
they have no genetic information
they can't change
they can't reproduce on their own
they have no protein components
7
Which of the following is found in animal cells?
chloroplast
centrioles
all of the above
cell wall
8
Prokaryotes are far simpler and smaller than Eukaryotes, and their DNA
is organized in chromosomes
is contained in a nucleus
none of the above
floats in the cytoplasm
9
Prokaryotes are found in this kingdom:
Animalia
Eubacteria
Plantae
Fungi
10
A health problem that causes low energy might be related to this organelle not functioning correctly:
golgi apparatus
nucleus
mitochondria
endoplasmic reticulum
11
Which is NOT true about ribosomes?
They are involved in making proteins.
They are made in the nucleolus.
They are found in viruses
They are found in bacteria.
12
Prokaryotes are considered more primitive than Eukaryotes because:
they don't have organelles to divide labor
they lack membrane bound organelles
all of the above
their DNA is not stored in a nucleus
13
This organelle is larger and more centrally located in a plant cell and stores water, food and waste.
nucleus
vacuole
cytoplasm
ER
14
Both eukaryotes and prokaryotes have all of the following EXCEPT:
cell membrane
ribosomes
nucleus
DNA
15
The nucleus is found in ________ and _______________ (function).
eukaryotes; stores genetic information
prokaryotes; stores genetic information
eukaryotes; produces and modifies proteins
prokaryotes; produces and modifies proteins
16
Centrioles coordinate cell division/mitosis and are found in ______ cells.
animal
fungi
plant
bacteria
17
Prokaryotes such as bacteria
have a nucleus and DNA
have neither a nucleus nor DNA
have a nucleus but not DNA
Have DNA but not a nucleus
18
If ribosomes don't work, sorry, no more...
energy!
cell membrane!
glucose!
proteins!
19
The organelle responsible for releasing energy from food is:
nucleus
chloroplast
mitochondria
lysosome
20
Viruses are similar to living cells in that they:
have a membrane
can break down sugars for energy
can make proteins on their own
find a way to reproduce
21
Which organelle(s) distinguish(es) a plant from an animal cell?
all of the above
cell wall
chloroplasts
large central vacuole
22
The main organelles involved in breaking down waste in the cell are:
lysosome and vacuole
mitochondria and nucleus
endoplasmic reticulum and golgi apparatus
nucleus and ribosome
23
Cells that need to break other cells down have many of this organelle:
lysosomes
mitochondrion
ribosome
vacuole
24
If chloroplasts stop working, sorry, no more...
energy!
glucose!
proteins!
cell membrane!
25
Where are ribosomes made?
nucleolus
golgi apparatus
endoplasmic reticulum
cytoplasm
26
The organelle indicated by Q is:
smooth ER
rough ER
golgi apparatus
mitochondria
27
Cells that facilitate movement would probably have more of this organelle:
endoplasmic reticulum
vacuole
nucleus
mitochondria
28
Cell walls function in plant, fungi, and bacteria to:
control what enters and exits the cell
store energy for future use
provide support and structure
store water and nutrients
29
Post offices sort, package and distribute mail. Which organelle serves a similar function?
lysosome
ribosome
golgi apparatus
nucleus
