Callus is
1 Tissue that forms embryo
2 An insoluble carbohydrate
3 Tissue that grows to form embryoid
4 An unorganised actively dividing mass of cells maintained in culture
Explanation:
Callus is a growing mass of unorganized plant parenchyma cells. In living plants, callus cells are those cells that cover a plant wound.

Totipotency means ____
1 Development of a seed from a cell in culture medium.
2 Development of a fruit from a cell in culture medium.
3 Development of an organ from a cell in culture medium.
4 None of these
Explanation:
The potential of a plant to grow and develop into a whole new multicellular plant is described as Cellular totipotency. In other words, the property of a single cell for differentiating into many other cell types is called totipotency. This is the property which is found only in living plants cells and not in animal cells (Except Stem cells). The term totipotency was coined in 1901 by Morgan.

The phenomenon that operates in the formation of root or shoot in a callus culture is
1 Differentiation
2 Redifferentiation
3 Dedifferentiation
4 None of these
Explanation:
The cells derived from shoot apical meristem and root apical meristem and cambium differentiate and matures to perform special functions. This act leading to maturation is termed as differentiation.

Meristem culture is free from ____
1 Fungi
2 Bacteria
3 Mycoplasma
4 Virus
Explanation:
Generally plant shoot apical meristems are virus free; to get rid of viruses in a chronically infested plant the technique of "Meristem culture" is used. Here the meristem dome is excised and planted aseptically on a synthetic medium. The meristem grows in to virus-free shoot that is rooted to get a virus free plant.

An explant is
1 Part of plant that is thrown away
2 Any part of plant used in hybridization.
3 Any part of plant used in tissue culture.
4 Cells used in somatic hybridization.
Explanation:
Any part of a plant taken out and grown in test tube under sterile conditions in special nutrient media is called as explant.
