Test: Tissue Culture (Old NCERT) - Question 1

Select the correct statement out of the following.

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 1

In suspension culture, single cell or small group of cells are suspended in a liquid medium. To avoid death of tissue culture/cell/tissues are regularly shifted to new culture flask having fresh nutrient media. Sterilization process of destroying microorganisms to produce contamination free culture.

Test: Tissue Culture (Old NCERT) - Question 2

Totipotency refers to

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 2

Totipotency is the capacity to generate a whole plant from any cell or explant. Any part of a plant is taken out and grown in a test tube, under sterile conditions in special nutrient media to regenerate a whole plant by virtue of to tipotency.

Test: Tissue Culture (Old NCERT) - Question 3

Which of the following should be used as an explant to generate a disease free plant?

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 3

Although the plant is infected with a virus, the meristem (apical and axillary) is free of virus. Hence, one can remove the meristem (shoot tip) and grow it in vitro to obtain virus-free plants.

Test: Tissue Culture (Old NCERT) - Question 4

Meristem culture is the culture of

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 4

Meristem is a localized group of cells, which are actively dividing and undifferentiated but ultimately give rise to permanent tissue. Cultivation of axillary of apical shoot meristems is called meristem culture. Meristem culture is carried out in potato, banana, cardamom, orchids (protocorm stage), sugarcane, strawberry, sweet totato, etc.

Test: Tissue Culture (Old NCERT) - Question 5

Somaclones are

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 5

Somaclones are genetically identical plants developed from any part of a plant by tissue culture micropropagation.

Test: Tissue Culture (Old NCERT) - Question 6

Given below is the flowchart showing the process of somatic hybridization. Identify A, B, C, D and E.


 

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 6

In somatic hybridisation, we isolate naked protoplasts by digesting their cell walls using digesting enzymes. Then isolated protoplasts fused together to form a hybrid protoplast which further grew to form a new plant.

Test: Tissue Culture (Old NCERT) - Question 7

Microporpagation involves

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 7

Micropropagation is the tissue culture technique used for rapid vegetative multiplication of ornamental plants and fruit trees by using small sized explants. Because of minute size of the propagules in the culture, the propagation technique is named as micropropagation.

Test: Tissue Culture (Old NCERT) - Question 8

A plant cell without cell wall is called

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 8

The plant cells without cell wall are called protoplasts.

Test: Tissue Culture (Old NCERT) - Question 9

A somatic hybrid between potato and tomato is named as

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 9

Pomato is somatic hybrid between potato and tomato that belong to two different genera.

Test: Tissue Culture (Old NCERT) - Question 10

Somatic hybrids in plants were first obtained between two species of _____ by Carlson et al. in 1972.

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 10

Somatic hybrids in plants were first obtained between two species of tobacco (Nicotiana glauca and N. langsdorfit) by Carlson et al. in 1972.

Test: Tissue Culture (Old NCERT) - Question 11

In plant tissue culture, cytokinins are responsible for the growth of

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 11

In plants tissue culture, cytokinins are responsible for the growth of shoots.

Test: Tissue Culture (Old NCERT) - Question 12

Hormone responsible for growth of the root in micropropagation is

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 12

Auxins are responsible for the growth of the root in micropropagation.

Test: Tissue Culture (Old NCERT) - Question 13

The enzymes required to obtain protoplast from a plant cell are

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 13

Cell wall of the plant cells is removed by digestion with a combination of pectinase and cellullase to obtain protoplast.

Test: Tissue Culture (Old NCERT) - Question 14

Match Column-I with Column-II and select the correct answer from the codes given below.

Test: Tissue Culture (Old NCERT) - Question 15

Meristem culture is used

Detailed Solution for Test: Tissue Culture (Old NCERT) - Question 15

Meristem culture is a process of culturing meristems (both apical and axillary) which is free from virus, used to obtain virus-free plants by rapid multiplication. It is also used to preserve germplasm characters. Example: banana, sugarcane and potato.
