Total questions: 20
Worksheet time: 10mins
What are advantages of asexual reproduction? (pick all that apply)
There is increased genetic diversity
The cell can reproduce quickly
Exact copies of the successful cells can be reproduced
Organisms can adapt to changing environments over generations
Why a cells generally so small?
Because the molecules they are made of are tiny
Because more cells can fit into an organism
Because moving nutrients across cell membranes is more efficient when they are smaller
Because more daughter cells can be reproduced when fewer resources are being used
What are the structures in a cell that are made of bundles of DNA?
ribosomes
mitochondria
organelles
chromosomes
What occurs during the cell cycle?
cells prepare and then divide into 2 daughter cells
cells are triggered to die off after a certain amount of time
cells fail to die off and reproduce uncontrollably
cells travel throughout the circulatory system
During the cell growth phase of cell division, what is occurring?
cell membranes and walls are forming
cells are splitting in half
new protein and organelles are being formed
chromosomes are enlarging
What is mitosis?
The fluid in the cell outside of the nucleus
The area of the cell that contains DNA
The part of a cell's life before cell division
The stage of cell division when the nucleus is divided
During which phase of mitosis are the chromosomes replicated?
prophase
metaphase
anaphase
telophase
During which phase of mitosis are two nuclear envelopes formed?
prophase
metaphase
anaphase
telophase
During which phase of mitosis do the spindle fibers first attach to the chromosomes?
prophase
metaphase
anaphase
telophase
What do spindle fibers do?
They make up the nuclear envelope
They hold the chromosomes together
They separate the chromatids
They give the cell its shape
How is cytokinesis different in plant cells than in animal cells?
Plant cells do not form spindle fibers during cell division
Plant cells form a cell plate that divides the cell instead of a cell membrane
Plant cells do not have chromosomes like animal cells have
Plant cells form nuclear envelopes in the daughter cells instead of cell membranes
During which phase do the sister chromatids separate and move to opposite ends of the cell?
prophase
metaphase
anaphase
telophase
What controls the cell cycle?
spindles and centromeres
oxygen and carbon dioxide
red and white blood cell circulation
internal and external regulatory proteins
What is cancer?
early cell apoptosis
uncontrolled cell growth
overly active external regulators
pluripotent stem cells
What is apoptosis?
animal cell mitosis
regulated cell division
programmed cell death
a prokaryote growth factor
What is differentiation?
stem cells developing into specific types of cells
different stages of cell reproduction
the beginning of mitosis
cell division
How are adult and embryonic stem cells different?
embryonic stem cells last longer than adult stem cells
retrieving adult stem cells kills the host, retrieving embryonic stem cells doesn't
embryonic stem cells can become any type of cell, adult stem cells can only become certain types of cells
embryonic stem cells are not useful for research and medical treatments, adult stem cells are
What are induced pluripotent stem cells?
stem cells that are taken from the umbilical cord
embryonic stem cells that are unable to differentiate
stem cells formed in a lab
adult stem cells that have been modified to act more like embryonic stem cells
How are prokaryotic chromosomes different from eukaryotic chromosomes?
they form a ladder
they are lined up into one long row
they are not enclosed in a nucleus
they are made up of lipids
What type of cell division occurs in prokaryotes?
sexual reproduction
meiosis
mitosis
binary fission
