The production of new characteristics by introducing new genes and altering the genome is called
Which of the following terms is used to describe the component isolated from a plant for in vitro culturing in the specific medium?
Explant culture is an in-vitro technique to organotypically culture cells from a piece or pieces of tissue or organ removed from a plant or animal.
To meet the demands of society, the in vitro production of a large number of plantlets in a short duration practised in the floriculture and horticulture industry is called
Micropropagation is a type of vegetative propagation of plants in tissue culture. In this propagation the plantlets of plants growing in tissue culture in vitro condition and then growing them out.
The term “protoplast” refer to the entire cell, excluding the cell wall: a plant, bacterial or fungal cell that had its cell wall completely or partially removed. A plant cell without a cell wall is Mycoplasma. It is an exception to the plant world.
In a tissue culture medium, the embryoids formed from pollen grains is due to
Cellular totipotency is the ability of a cell to grow whole plant or whole plant part from that particular cell only.
An explant is a
Plant tissue culture is the technique of maintaining and growing aseptically plant cells, tissues or organs on artificial medium in test tube under controlled environmental conditions. The part which is cultured is called explant, i.e., any part of a plant taken out and grown in a test tube, under sterile conditions in special nutrient media. Plant tissue culture relies on the fact that the plants have a capacity to generate a whole plant from any cell/explant (cellular totipotency). Single cells, plant cells without cell walls (protoplasts), pieces of leaves, stems or roots, embryo, anther can be used to generate a new plant.
To obtain disease-free plants through tissue culture techniques, the best method is
The technique of obtaining a large number of plantlets by the tissue culture method is called
Micropropagation, means rapid vegetative multiplication of valuable plant material for agriculture, horticulture and forestry. Propagation through tissue culture is called micropropagation.
Somaclonal variation appears in plants
Somaclonal variation is the variation seen in plants that have been produced by plant tissue culture. Chromosomal rearrangements are an important source of this variation. Somaclonal variation is not restricted to, but is particularly common in, plants regenerated from callus.
Micropropagation is the
Tissue culture is a technique of growing plant or animal cells, tissues or organs in a sterilized nutrient/ culture medium under controlled environmental conditions. Plant tissue culture specifically is also known as micropropagation because it involves rapid multiplication of small amount of plant material to produce more progeny.
