Mitosis
Plants can reproduce by asexual reproduction. All the new plants are identical.

Mitosis

This Biology quiz is called 'Mitosis' and it has been written by teachers to help you if you are studying the subject at middle school. Playing educational quizzes is a fabulous way to learn if you are in the 6th, 7th or 8th grade - aged 11 to 14.

Cell division is one of the processes studied in middle school Biology. This quiz focuses on the main type of cell division, mitosis, which is used by the body for growth and repair. Mitosis takes place when plants or animals need to make new cells for growth or repair. The genetic code for an organism is carried by the chromosomes in the nucleus of every cell. Mitosis is a type of cell division where a body cell divides to form two genetically identical cells.

1.
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
2.
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
3.
Mitosis results in cells which are...
different
larger
varied
identical
Mitosis creates cells that are genetically identical to the original cell
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.
During mitosis, a cell divides to form how many cells?
1
2
3
4
The two new cells are referred to as daughter cells
6.
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
7.
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
8.
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
9.
Which structures pull the chromosomes apart during cell division?
Poles
Membranes
Spindle fibers
Nuclei
Each chromosome is attached to a fiber 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
10.
Before the cell can divide, what must it copy?
Its nucleus
Its DNA
Its hormones
Its bacteria
Chromosomes are made from strands of DNA
