1.
In micropropagation, explants are usually taken from:
Seeds
Shoot tips
Pollen grains
Flowers after fertilisation
2.
Why is the agar medium given plant hormones?
To kill bacteria
To provide energy
To stimulate root and shoot growth
To cause meiosis
3.
In cloning a mammal, the egg cell is:
Fertilised by sperm
Kept with its own nucleus
Heated to divide
Enucleated
4.
A cloned animal is genetically identical to:
The animal that donated the body-cell nucleus
The egg donor
The surrogate mother
Both parents equally
5.
What is used to stimulate the new cell to divide?
Plant hormones
An electric shock
Restriction enzymes
Insulin
6.
A disadvantage of producing crops by micropropagation is:
Plants are genetically identical, so all may be affected by one disease
It is very slow
It needs pollinators
Plants show great variation
7.
Which statement best describes Aseptic technique?
Methods that prevent contamination by microorganisms.
An organism that is genetically identical to its parent or to another organism.
Containing two sets of chromosomes, as in body cells.
A female animal into whose uterus an embryo is implanted, which carries it until birth.
8.
Which statement best describes Somatic cell nuclear transfer?
An organism that is genetically identical to its parent or to another organism.
A female animal into whose uterus an embryo is implanted, which carries it until birth.
Placing the nucleus of a body cell into an enucleated egg cell to produce a cloned embryo.
Containing two sets of chromosomes, as in body cells.
9.
Which statement best describes Explant?
A small piece of tissue taken from a parent plant to be grown in tissue culture.
Placing the nucleus of a body cell into an enucleated egg cell to produce a cloned embryo.
A female animal into whose uterus an embryo is implanted, which carries it until birth.
Methods that prevent contamination by microorganisms.
10.
Which statement best describes Agar medium?
An organism that is genetically identical to its parent or to another organism.
A jelly containing nutrients and plant hormones on which explants are grown.
A female animal into whose uterus an embryo is implanted, which carries it until birth.
Describes a cell that has had its nucleus removed.
