Telophase
Cell prepares for cell division
1. What occurs during the G2 phase?
2. What 3 phases make up interphase?
G1, S & G2
3. What are the 2 parts of cell division?
Mitosis & cytokinesis
4. What phases make up mitosis?
Anaphase
Prophase, metaphase, anaphase, telophase
5. What occurs during cytokinesis?
Cytoplasm divides
6. What occurs during the S phase?
Chromosomes replicate
7. What percent of a cell’s life is spent in interphase?
8. What occurs during the G1 phase?
75%
Cell performs its normal functions
9. What percent of a cell’s life is spent in cell division?
25%
10. Why does a cell’s DNA double during interphase?
and amount of DNA
So the daughter cells will each have the correct type
11. When would a cell perform its normal functions?
12. What occurs during mitosis?
G1
The nucleus (DNA) splits
Chromosomes: Label the diagram below by dragging and dropping the names in the appropriate locations.
Answer the questions that follow.
Centromere
Sister Chromatids
1. How many sister chromatids make up a chromosome?
2
2. Look at the picture of an actual chromosome to the right. What are the thin, wiry strands?
3. What is similar about the 2 sister chromatids?
They are the exact same DNA
4. What is the name of the protein disc at the center of the chromosome?
5. How many chromosomes are in a human body cell?
centromere
46
6. When does a chromosome take the “X” shape shown above? during prophase of mitosis
7. What is the term for uncondensed DNA during interphase? chromatin
DNA
Mitosis: Drag and drop the following pictures into the appropriate places in the cells. Label the phases of
mitosis.
Interphase
Prophase
Cytokinesis
Metaphase
Telophase

chromatin
Anaphase
Condensed replicated chromosome

4. If a mosquito cell has 6 chromosomes during interphase, how many will the daughter cells have after
mitosis? 6

Questions
1. What is structure A?
centriole
2. What organelle is structure B?
nucelus
3. What is structure C?
chromosomes
4. What form does the DNA have in
prophase?
condensed replicated chromosome
1. What is structure D?
spindle fibers
2. Where do the chromosomes line
up in the cell?
center of the cell
3. How many chromosomes are in
this cell?
4
anaphase
1. What happens to the sister
chromatids during this phase?
pulled apart
2. What is the function of the spindle
fibers?
to separate the chromatids
telophase
1. What is starting to reform around
the DNA?
nucleus
2. How many chromosomes are in
the resulting daughter cells?
4
cytokinesis
1. What form does DNA have during
cytokinesis?
chromatin
2. What forms in animal cells that
separates the 2 cells?
cleavage furrow
3. What forms in plant cells that
separates the 2 cells?
cell plate
Asexual Reproduction: Label the following pictures as one of the types of asexual reproduction.
Vegetative Reproduction
Budding
Binary Fission
Regeneration
Vegetative Reproduction
Binary Fission
Vegetative Reproduction
1. What is an example of a benign tumor? wart
2. What is an example of a malignant tumor? lung cancer
3. What is the difference between a malignant and benign tumor? Malignant tumors are harmful and take
over the infected tissue; a benign tumor is harmless and does not take over the tissue
4.
a. Are the parent and offspring the same or different from asexual reproduction? same
b. Why? Offspring is a product of the parent dividing- it has the same DNA and therefore, looks the
same
5. How do bacteria reproduce? Binary fission
6. How does a hydra reproduce?
budding
7. One of the types of asexual reproduction is not shown above.
What is this type of asexual reproduction (hint: star fish)? fragmentation
