Cell Cycle Flashcards
The genetic material inside the
nucleus
- Cell
- Nucleus
- Chromosome
- DNA
What is a session of DNA called?
Gene
What is a cell cycle?
a series of events that takes place in a cell as it grows and divides
The cell cycle consists
of 3 different stages:
- Interphase
- Mitosis
- Cytokinesis
What are Interphase?
- The cell gets ready to divide.
- The cell grows, DNA duplicates and more organelles are made.
What are Mitosis?
Reason One
- This is where cells divide which produces
daughter cells identical to the parent.
What are Mitosis?
Reason Two
Diploid mother cell then Cell division to Diploid daughter cells
What is Cytokinesis?
- Cytokinesis, in biology,
- is the process by which one cell physically divides into two cells.
Which phase is the longest in the cell cycle?
Growth
What is/are the product(s) of mitosis?
2 identical cells
Which phase is the shortest in the cell cycle?
Mitosis
Why is mitosis important?
- Repair
- Growth
Interphase
Chromosomes are replicated
Chromosomes
line up in the middle of the cell
Mitosis
Chromosomes are pulled
apart from the poles of the cell
Cytokinesis
Whole-cell divides
Which of these best describes the cells produced through mitotic cell
division?
Two genetically identical daughter cells
Which of these processes does not involve mitosis?
Producing gametes
Is this Statement True:
Mitosis is the division of chromosomes
True
Cells need to divide…
For your body to grow and for body tissue such as skin to continuously renew itself these cells go through the cell cycle
A cell spends…
Most of its time in what is called interphase
During this time…
Replicates its chromosomes, and prepares for cell division.
The cell then leaves
interphase, undergoes mitosis, and completes its division.
Mitosis makes …
identical cells
Skin cell…
replacing what was lost
The process of mitosis…
Is essential to life: it provides new cells for growth and replaces old and dying cells.
The original cell is…
Called the mother cell and the two new cells are called daughter cells.
The last phase of the cell cycle is called cytokinesis
The process…
By which one cell physically divides into two cells
How does cytokinesis help…
tissue growth and tissue repair
Mitosis is part of the cycle where… separate
Chromosomes
Why is mitosis important for organisms?
Mitosis is crucial for:
- organisms making new cells
- for growth and repair
Why mitosis occurs most rapidly when organisms are young
Organisms have a fast rate of growth when young, so many new cells are needed.
What is mitosis?
The separation of the nucleus after duplication of DNA.
What happens when cells differentiate?
They specialise in performing a function.
Why is mitosis imporant?
It allows tissue to grow or replacement of damaged cells.
How long does it take approximately for a human cell to complete a cell cycle?
20-24 hours
How many chromosomes does a normal body cell have?
46 (23 pairs)
What does haploid mean?
It refers to having a full set of chromosomes.
What happens in the final stage of the cell cycle?
Cytoplasm and cell membrane divide to produce two genetically identical cells.
Why the cell have to grow bigger before mitosis?
To grow big enough to contain more subcellular structures form from duplication.
Compare the daughter cells that are produced through mitosis with the partner cell.
There are two new daughter cells, each genetically identical to the parent cell.
