Which of these is NOT a part of cell theory
All living cells are eukaryotes
cells are the simplest unit of structure/function within a cell
all living things are made up of cells
all new cells come from already existing cells
Which of these is a prokaryote?
What conclusion can we make about this cell?
It is a prokaryote because it has a nucleus
It is a prokaryote because it DOES NOT have a nucleus
It is a eukaryote because it has a nucleus
It is a eukaryote because it DOES NOT have a nucleus
Which of the following is NOT part of the cell membrane?
phospholipids
protein transport channels
mitochondria
two layers
Which statement about these cells is true
The blue one is a prokaryote and the green one is a eukaryote.
The blue one is a eukaryote and the green one is a prokaryote
Both cells are eukaryotes.
Both cells are prokaryotes.
What are the orange structures with the squiggly lines in them called?
Mitochondria
Endoplasmic Riticulum (ER)
Ribosomes
Nucleus
What do the orange structures with the squiggly lines in them do?
Store and protect DNA
Transport molecules
Make proteins
Harness energy
The difference between the smooth ER and the rough ER is
the smooth ER has ribosomes and the rough ER does not
the rough ER has ribosomes and the smooth ER does not
the smooth ER holds DNA and the rough ER does not
the rough ER holds DNA and the smooth ER does not
What is the purpose of the nucleus?
make proteins
harness energy from the sun
store and protect DNA
dispose of waste
What do lysosomes do?
store molecules cells need
harness energy from the sun
break molecules down
make proteins
Ribosomes
make DNA
make RNA
make proteins
store molecules
The Endoplasmic Riticulum is responsible for
allowing things in and out of the cell
making proteins
storing and protecting DNA
transporting molecules around within a cell
The blue squiggly stuff next to the nucleus is the
vacuole
endoplasmic riticulum (ER)
cell membrane
chloroplasts
If a molecule requires a transport protein to cross the cell membrane, but does not require extra energy, that is
simple diffusion
facilitated diffusion
active transport
endo/exocytosis
If a molecule requires a transport protein to cross the cell membrane and requires extra energy, that is
simple diffusion
facilitated diffusion
active transport
endo/exocytosis
Large molecules and groups of smaller molecules ENTER the cell through
endocytosis
exocytosis
active transport
simple diffusion
Large molecules and groups of smaller molecules Exit the cell through
endocytosis
exocytosis
active transport
simple diffusion
The largest organelle in this cell (it's light blue) is the
chloroplast
ribosome
central vacuole
Endoplasmic Riticulum
The purpose of the largest organelle in this cell (it's light blue) is
it harnesses energy from the sun
it makes proteins
it stores molecules
it moves molecules around inside the cell
All cells have each of the following EXCEPT
ribosomes
cell membrane
cytoplasm
cell wall
The cell membrane has proteins embedded within it which allow large molecules to pass through it. Which organelle made these proteins?
nucleus
nucleolus
ribosomes
lysosomes
Plant cells have ____________________ which allow them to carry out photosynthesis
ribosomes
chloroplasts
nucleolus
cell membranes
Small molecules pass straight through the cell membrane without any assistance at all in a process called
simple diffusion
facilitated diffusion
active transport
endo/ exocytosis
Which of these is simple diffusion?

Which of these is active transport?
Which of these shows endocytosis?
Molecules move from high concentration to low concentration during (select all that apply)
simple diffusion
facilitated diffusion
active transport
endo/ exocytosis
Homeostasis refers to
An organism's lifetime
an organism maintaining stable conditions inside of its body
which organelles an organism has
how many cells an organism has
Which of these is an example of an organism maintaining homeostasis.
When it gets dark outside, our pupils dialate to allow more light into our eyes.
When our bodies get too warm, we sweat to release heat energy. which cools our bodies back down to our normal temperature
When we are scared, our hair stands up on end.
Human nerve cells typically do not regenerate
which of these shows an organism maintaining homeostasis?
Hypotonic means
that side of the membrane has more stuff dissolved in it
that side of the membrane has less stuff dissolved in it
both side of the membrane have equal amounts of stuff dissolved in it.
Hypotonic is a made up word
If a cell is placed in a HYPERtonic solution, that cell will
swell up because water will rush in
shrivel up because water will rush in
swell up because water will rush out
shrivel up because water will rush out
