Which of the following structures is found in the cytoplasm?
nucleolus
ribosome
chromatin
cell wall
Unlike the cell membrane, the cell wall in a plant is
found in all organisms.
composed of a lipid bilayer.
a flexible barrier.
usually made of tough fibers called cellulose
Diffusion is the movement of molecules from
an area of low concentration to an area of high concentration.
an area of high concentration to an area of low concentration.
an area of equilibrium to an area of high concentration.
all of the above
Which of the following is a function of the nucleus?
stores DNA
controls most of the cell’s processes
contains the information needed to make proteins
all of the above
Homeostasis will be most affected by the removal of the
vacuole
cell wall
chloroplast
cell membrane
A plant has been removed from its natural environment and placed into a body of water that contains a higher concentration of salt than the inside of each plant cell. The plant promptly wilts. This situation is most similar to which event?
seaweed put into fresh water
a land plant put into tap water
a freshwater plant put into sea water
a freshwater plant put into distilled water
What will mostly likely happen if you removed all the mitochondria from a cell?
It will be unable to carry out respiration to make ATP.
It will lose water through osmosis.
It will break down the ribosomes in the cell.
It will be unable to photosynthesize
Which organelle converts the chemical energy stored in food into ATP, which is more convenient for the cell to use?
chloroplast
Golgi apparatus
endoplasmic reticulum
mitochondrion
Looking at a cell under a microscope, you note that it is a prokaryote. How do you know?
The cell lacks cytoplasm.
The cell lacks a cell membrane.
The cell lacks a nucleus.
The cell lacks genetic material.
Jim is in a crowd of people at the mall looking for his girlfriend Tammy, who was supposed to meet him for dinner. Jim realizes Tammy is across the room as he catches a whiff of her overpowering perfume, 'Paris #6'.
Which process explains why Jim is able to smell the perfume?
Osmosis
Diffusion
Active Transport
Facilitated diffusion
Which of the following statements is part of the cell theory?
Cells are composed mostly of empty space.
Cells are generally large enough for the unaided eye to see.
All cells are produced from existing cells.
Only animals are made up of cells.
Cell drinking; cell eating. Both are modeled here and are examples of
Osmosis
Diffusion
Endocytosis
Exocytosis
The illustration shows a model of the transport of solute particles from outside the cell to inside the cell
The model illustrates active transport because energy is required for solute particles to cross the cell membrane.
The model illustrates diffusion because solute particles are moving from an area of higher concentration to an area of lower concentration.
The model illustrates facilitated diffusion because protein channels allow solute particles to cross the cell membrane.
The model illustrates osmosis because water molecules are moving from an area of higher concentration to an area of lower concentration.
Proteins built into the cell membrane which assist with the movement of materials are called
receptor proteins
transport proteins
channel proteins
marker proteins
Which of the following is NOT a characteristic of active transport?
It moves substances against a concentration gradient
it requires energy from the cell
it involves facilitated diffusion
it may use carrier proteins that often function as the sodium potassium pump
Molecules that are too large to be moved through the cell membrane can be transported INTO the cell by
osmosis
exocytosis
endocytosis
diffusion
The difference between smooth and rough ER is that
smooth ER has no role in the cell
rough ER produces vesicles
rough ER has ribosomes on its surface
smooth ER never touches the nucleus
The function of the Golgi apparatus is to
control the cell’s functions .
package and distribute proteins (post office) .
store water.
allow things in and out of the cell.
Which two processes does this diagram most directly model?
Energy conversion and synthesis of a new molecule
Synthesis of new molecules and homeostasis
Transport of molecules and energy sources
Homeostasis and transport of molecules
