Total questions: 9
Worksheet time: 11mins
differnetiation
a pro9cess that creates special structures and functions
stem cells
undifferentiated cells that can become differentiated into one or more types of specialized cells
cell cycle
a repeated pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells
chromosome
one long continuous thread of DNA that consistes of thousands of genes and regulatory information
gene
a section of DNA with instructions for making a protein
two identical chromatids (halves of a duplicated chromosome)
sister chromatids
region of the condensed chromosomes that looks pinched
centromere
ends of hte DNA molecule
telomere
uncontrolled cell division
cancer
spreading of diseases from one organ to others
metastasize
Reorder the following events from egg and sperm to embryo
The male sperm travels to thye female egg to fertilize it
Once the egg is fertilized, the resulting zygote has all of its chromosomes for the first time
It begins to go through mitosis, repeatedly making identical cells
That clump of identical cells eventually starts to go through differentiation,
The resulting specialized cells organize into tissues, organs, and organ systems that make up the embryo
Reorder the following from smallest to biggest
cell
tissue
organ
organsystem
organism
What are the two main purposes for cell division?
mitosis and cytokinesis
growth and repair
growth and reproduction
repair and apoptosis
Match the following steps of mitosis with what happens in that phase
prophase
spindle fibers form, nuclear membrane dissolves, chromosomes condense
metaphase
chromosomes line up in the middle of the cell
anaphase
chromosomes are pulled apart
telophase
spindle fibers dissolve, nuclear membrane reforms, chromosomes decondense
cytokinesis
cytoplasm divides into 2 separate cells
Which is NOT a part of iinterphase?
Gap 1
Gap 2
Gap 3
Synthesis
Which is NOT a cause of cancer?
Vesicle factors
lifestyle factors
carcinogens
biological factors
internal regulatoin
a chemical control system that responds to signals from a cell's DNA
external regulation
a chemical control system that responds to signals from hormones, nutrients, etc
instintual regulation
something made up because quizziz won't let there just be two thintgs in this kind of question
