Cell Division Flashcards
What type of microscope is used in a school lab to observe cells
The light microscope
What happens during prophase
The nuclear membrane disappears and the spindle forms.
After mitosis, what happens in an animal cell ?
The cleavage is formed
After mitosis, what happens in an plant cell ?
The cell plate is formed.
Define mitosis
This is cell division that forms two identical daughter cells
Explain the term cancer
This is a group of disorders due to uncontrolled rate of mitosis
Explain the term diploid
These are cells that have 2 of each chromosomes
What is the function of mitosis in single-celled organisms
For asexual reproduction
What is the function of mitosis in multi-celled organisms
The repair of tissue or tissue growth
what term is used to describe the long stage of the cell cycle when cell division is not occurring
interphase
Name two types of biomolecules that are produced in the cell during the interphase
protein
fat
carbohydrate
Name an organelle that is replicated during the interphase
The mitochondria
Give any two other changes which will have occurred in the cell by the end of the interphase
The nuclear membrane disappears.
The chromosome becomes visible unv
Give any two other changes which will have occurred in the cell by the end of the interphase
The nuclear membrane disappears.
The chromosome becomes visible
Why do red blood cells not undergo division ?
No nucleus
Give a cellular process that occurs during the interphase
photosynthesis
growth
Respiration
Name the stage of mitosis in which the chromosomes are located at the equator of the cell before they begin to separate
Metaphase
To what are the chromosomes attached in the metaphase ?
They are attached to the spindle
What type of cell does a cell plate from ?
In a plant cell
Name the stage in which chromosomes are separated and drawn near the poles
The anaphase
Give a location where mitosis occurs in flowering plants
buds
root tips
shoot tips
Give the names of 2 processes involving DNA which take place during the interphase
transcription
replication
mitosis is divided into 4 stages
prophase
anaphase
metaphase
telephase
At what stage, would you expect to see the spindle fibres contracting
Anaphase
How do you determine if a cell is undergoing the metaphase ?
The chromosomes are on the equator
