Plants can reproduce by asexual reproduction. All the new plants are identical.
Unit 2 - Mitosis
This GCSE Biology quiz on mitosis tests how cells divide for growth and repair, following chromosomes as they line up, separate, and form two identical daughter cells.
1 .
Mitosis results in cells which are...
different
larger
varied
identical
Mitosis creates cells that are genetically identical to the original cell
2 .
In which of the following is mitosis most likely to take place?
A virus
Plant roots
A nucleus
Dead cells
Mitosis takes place in any living animal and plants cells which are undergoing growth and repair
3 .
Plants can reproduce by asexual reproduction. All the new plants are...
identical
different
smaller
varied
Individuals that are identical genetically to the parent organism are called clones
4 .
In humans, there are 46 chromosomes inside the nucleus of body cells. How many chromosomes are present in cells after mitosis?
23
46
47
24
Remember, mitosis produces daughter cells that are genetically identical to the parent cell therefore the number of chromosomes must be the same
5 .
Mitosis produces new cells for...
growth and repair
the sake of it
making gametes
reproduction and excretion
In different species, new cells formed by mitosis can be used for regrowing lost body parts and it also allows asexual reproduction to take place
6 .
Before the cell can divide, what must it copy?
Its nucleus
Its DNA
Its hormones
Its bacteria
Chromosomes are made from strands of DNA
7 .
Which structures pull the chromosomes apart during cell division?
Poles
Membranes
Spindle fibres
Nuclei
Each chromosome is attached to a fibre which acts like a rope pulling and splitting each chromosome into 2 halves. They are identical copies of each other and move to opposite ends of the dividing cell
8 .
Which type of cell division makes sex cells: eggs and sperm?
Mitosis
Cloning
Asexual
Meiosis
This produces cells with only half of the genetic information of the original cell
9 .
During mitosis, a cell divides to form how many cells?
1
2
3
4
The two new cells are referred to as daughter cells
10 .
Body cells have 2 sets of chromosomes found in pairs but gametes have how many sets?
1
2
3
4
Gametes, eggs and sperm, have half the number of chromosomes which are unpaired. This means there is one set of chromosomes and not two. This is due to the halving of the chromosome number which happens when gametes are made
