Mitosis plays an important role in body growing and replacing worn-out or damaged cells. true or false?
True
Which process makes gamete cells (sperm or egg)?
Meiosis
If cells divide all the time without control, it can lead to formation of ____
cancer
How many chromosomes are in a nucleus of human cell?
46
The 4 stages of mitosis in order are:
1.
Prophase
2.
Metaphase
3.
Anaphase
4.
Telophase
Followed of splitting of cytoplasm called
Cytokinesis
Cell cycle Mitosis Phases
Read the description and guess the phases of cell division.
Flip the card to find the correct answer.
“The cell grows, performs normal functions, and duplicates its DNA in preparation for division. It includes the G₁, S, and G₂ phases. DNA is in loosely compacted chromatin form.”
Interphase
Cell cycle Mitosis Phases
Read the description and guess the phases of cell division.
Flip the card to find the correct answer
“Chromosomes condense and become visible, the nuclear envelope breaks down, and spindle fibers begin to form from the centrosomes.”
Prophase
Cell cycle Mitosis Phases
Read the description and guess the phases of cell division.
Flip the card to find the correct answer
“Chromosomes line up at the cell’s equator (metaphase plate), attached to spindle fibers from opposite poles”
Metaphase
Cell cycle Mitosis Phases
Read the description and guess the phases of cell division.
Flip the card to find the correct answer.
“Sister chromatids are pulled apart by the spindle fibers toward opposite poles of the cell.”
Anaphase
Cell cycle Mitosis Phases
Read the description and guess the phases of cell division.
Flip the card to find the correct answer.
“Chromatids reach the poles, nuclear envelopes reform around each set of chromosomes, and the chromosomes begin to de-condense.”
Telophase
Cell cycle Mitosis Phases
Read the description and guess the phases of cell division.
Flip the card to find the correct answer
“The cytoplasm splits, forming two separate daughter cells, each with its own nucleus and complete set of organelles.”
Cytokinesis
If a cell in interphase has 4 chromosomes, how many chromosomes will be in the daughter cells after mitosis?
4
E. coli divides by binary fission.
true
According to the video, if a single E. coli cell starts dividing, nearly five thousand billion billion bacteria (sextillion 1021) bacteria will be produced after 24 hours.
