1.	What do you understand by micropropagation?
Answer» The modern technique of rapid multiplication of plants through tissue culture is called micropropagation. This technique has been used for multiplication of novel plants at commercial level. By this technique, a large population of similar plants can be raised in a small space in a relatively short time.

Discussion

2.	What is an artificial seed?
Answer» The encapsulated somatic embryo is called artificial seed. The somatic embryo is protected by covering it with calcium alginate beads or by desiccating it. Thus artificial seeds are produced from somatic embryos.

Discussion

3.	Comment on Ti plasmid.
Answer» Among the various vectors used in plant transformation, the Tiplasmid of Agrobacterium tumefaciens has been used extensively. This bacterium contains large-sized plasmid, known as Ti-plasmid (tumour-inducing plasmid) and a portion of this plasmid referred to as T-DNA (transferred DNA). When is transferred to plant genome, in the infected cells it causes these plant tumours (crown galls). This means that A. tumefacient has natural ability to transfer T-DNA of its plasmid into the plant genome (plant chromosomes) upon infection of cells at the wounded site and therefore this bacterium is known as ‘natural genetic engineer of plants’. Ti-plasmid can be used as a vector for inserting useful foreign genes into a genome of plant cells.

4.	What is the embryo rescue technique? Write its importance
Answer» It is very difficult to produce hybrids in case of interspecific and inter-generic crosses (crosses between distantly related plants), because abnormal development of the endosperm causes the premature death of the hybrid embryo and leads to sterile seeds. The embryo from such sterile hybrid seeds can be excised at an appropriate time and cultured on a suitable nutrient medium to produce novel hybrids which are otherwise not possible. This is known as Embryo Rescue. Several useful hybrids were produced in a variety of crops using this technique.

Discussion

5.	Write a note on the steps of tissue culture.
Answer» 1. Selection of explant and pretreatment: Selection of explant depends on objective and experimental requirements. For callus culture, and healthy, part of the plant can be used as explant. The explant is washed under running water with the help of chemical Tween-20. This treatment cleans dust and microbes present on the surface. 2. Surface Sterilization of explant: The selected explants are surface sterilized by appropriate disinfectant chemical under laminar airflow. This results in to complete sterilization of explant. Depending upon the nature of explant various types of disinfectants such as Mercuric chloride (HgCl₂), Ethanol, Silver nitrate (AgNO₃), Bromine or Chlorine water can be used. 3. Initiation of Culture: The surface-sterilized explant is transferred on a suitable nutrient medium under aseptic conditions and transferred to the culture room. In a culture chamber, callus formation is initiated in due course of time. The explant and callus may be transferred to fresh medium for multiplication.

41.

What is the nature of solution if D = 0?

Answer»

If D = 0, i.e. a₁b₂ – b₁a₂ = 0, then the two simultaneous equations do not have a unique solution.

Examples:

i. 2x – 4y = 8 and x – 2y = 4

Here, a₁b₂ – b₁a₂ = (2)(-2) – (-4) (1)

= -4 + 4 = 0

Graphically, we can check that these two lines coincide and hence will have infinite solutions.

ii. 2x – y = -1 and 2x – y = -4

Here, a₁b₂ – b₁a₂ = (2)(-1) – (-1) (2)

= -2 + 2 = 0

Graphically, we can check that these two lines are parallel and hence they do not have a solution.
