CHALLENGE QUESTION: Which of the following provides evidence for the hypothesis that prokaryotes evolved before eukaryotes.
prokaryotes are more complex
prokaryotes have no nucleus and fewer genes
eukaryotes are multicellular which makes them simpler
prokaryotes grow into eukaryotes
Cell structures that perform specific functions are called

What are the two types of cell transport?
Passive and Active
Active and Facilitated
Passive and Facilitated
None of the above
In passive transport, substances move across the cell membrane ________ the concentration gradient
AGAINST
ALONG
WITH
BETWEEN
Which example describes diffusion?
Water moving across a semi-permeable membrane

Ions moving through an ion channel
All of the above
What macromolecule is embedded into the lipid bilayer and helps to transport molecules?
Carbohydrate
Lipid
Protein
Nucleic Acid
Which describes a hypotonic environment?
Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell
Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell
Concentrations of water are equal inside and outside the cell
Which describes a hypertonic environment?
Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell
Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell
Concentrations of water are equal inside and outside the cell

Endocytosis
Receptor-mediated
Exocytosis
Why do organisms use the cell cycle?
to grow

to make unique cells
Unicellular organisms use the cell cycle to:
develop
heal
reproduce
all of the above
none of the above
During which part of the cell cycle is DNA replicated?
interphase
mitosis
cytokinesis
Which part of the cell cycle is divided into prophase, metaphase, anaphase, and telophase?
interphase
mitosis
cytokinesis
What does DNA replication mean?
dividing the cytoplasm
copying the organelles
copying the nucleus
none of the above
The regular sequence of growth and division that cells undergo is known as the
cellular respiration
photosynthesis
replication
cell cycle
What happens at the end of interphase?
the cell splits into 2 identical cells
the cell's nucleus divides
the DNA unwinds
the cell is preparing for mitosis
Simon looks at an image of a slide and notices that all of the chromosomes are lined up in along the middle of the cell. He is likely looking at a cell that is in
prophase
metaphase
anaphase
telophase
Which statement best describes chromosomes?
They carry out cellular respiration
They consist of the pigment chlorophyll
Their structure is only visible during interphase
They consist of tightly coiled strands of DNA and proteins
Why is it so important to replicate DNA?
so that each daughter cell is unique
to release energy
to make sure that the daughter cells are genetically identical to the parent cells
all of the above
During which phase of mitosis does cytokinesis begin?
prophase
metaphase
anaphase
telophase
