During which phase of the cell cycle does the cell spend the most time?
Mitosis
Cytokinesis
Interphase
Match the image to the correct answer
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
Label the parts of the Cell Cycle
G1
S phase
G2
Mitosis
Mitosis is the division of the (a)
Click where DNA replication takes place
Match each phase with its correct description
Cell grows rapidly while carrying out normal functions.
G1 Phase
Cells must replicate their DNA before cell division to ensure that identical genetic information is passed to the next generation.
S Phase
FINISHES GROWING
Errors in DNA replication are checked- if something is wrong, cell needs to fix its errors before it divides!
G2 Phase
Put the Cell Cycle phases in order
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
What happens during G1 phase
Cell grows rapidly
DNA replication
Checks for errors in DNA
Cell divides
Label the picture
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
The first phase of Mitosis is called ________
Prophase
Anaphase
Interphase
Telophase
Put the Cell Cycle events in order
Cell grows
DNA replicates
Cell prepares for Mitosis
Cell divides
(a) is the uncontrolled growth of cells, often resulting in a tumor or mass of abnormal cells
Which viral life cycle allows viral genetic material to lay dormant (inactive) while the host cell reproduces?
lytic
mitosis
lysogenic
S phase
The projections on the surface of this virus allow the virus to —
move inside a host cell
attach to a host cell
control a host cell’s DNA
signal other viruses to infect a host cell
What part of a virus is the protein capsule that houses the genetic material (DNA/RNA)?
tail
nucleus
capsid
glycoprotein
Viruses are...
prokaryotic
eukaryotic
non-living
endospores
Viruses using the (a) cycle gives the host organism a quick onset of symptoms while viruses in the (b) cycle can not show symptoms for years.
Which organelle is responsible for converting the energy in glucose into cellular energy?
When a virus invades a living cell, its ____________ takes over the cell's functions.
outer coat
genetic material
core
cytoplasm
Which one needs a host replicate?
Virus
Bacteria
The flu (influenza) is a...
Virus
Bacteria
Match the following pictures to their names:
Eukaryotic Cell
Prokaryotic Cell
Bacteriophage virus
Flu virus
Edward Jenner invented the first modern (a) in 1796. Vaccines are substances that stimulate the production of (b) and provide immunity against a (c) .
Unlike (a) , viruses cannot reproduce on their own. Viruses need a (b) cell to reproduce.
Which statement best describes how a virus replicates?
A virus divides into two identical virus particles before infecting the host cell.
A virus enters a host cell and uses the materials from the host cell to produce new virus particles.
Multiple virus particles fuse and form a large particle that breaks apart, releasing new virus particles.
Multiple virus particles break down in component parts, which then reassemble into new copies of the virus.
HIV is caused by which of the following pathogens.
virus
bacteria
fungus
protozoan
Cancer is defined as the
uncontrolled division of mutated cells
normal division of cells
normal DNA replication
abnormal ATP synthesis
The growth phase of the cell cycle is called
Interphase
Telophase
Prophase
Anaphase
In this random order, which stage shows chromosomes splitting; moving to opposite ends of the cell?
I
II
III
IV
V
Why do stomach cells function differently than skin cells?
They contain entirely different DNA
They use different genes in the DNA

Skin
What type of cells are these? They make up your digestive system and help break down food.
Red Blood
Intestinal
White Blood

What is one goal of cellular differentiation?
To create many identical copies of cells.
To make stem cells for use in the future.
To make single-celled organisms.
To make specialized cells to maintain homeostasis.
Stem cells are cells that...
grow uncontrollably
are undifferentiated
never divide
Stem cells can replace specialized cells within damaged tissue. Once they are in place, stem cells receive chemical signals which activate the appropriate set of genes. This demonstrates that which of the following plays a role in cell differentiation?
radiation
environment
antibodies
blood type
The diagram shows how specialized body cells can develop.
Which of the following best explains why cells that contain the same genetic material do not develop into the same types of cells?
Because internal and external stimuli can trigger the activation of specific genes in the DNA of cells
Because random mutations can occur in the DNA of cells during early embryonic development
Because messenger RNA is converted to transfer RNA when cell differentiation begins
Because chemical signals that are released during the cell cycle can result in the linking of similar genes
As a fertilized egg divides, the cells differentiate because they —
contain a lipid bilayer
can clump together
metabolize sugars rapidly
have specific genes activated
