Identify the incorrect statement:
1 Somatic hybridization has been used to produce pomato though it is not used commercially
2 Methylophilus methylotropus [bacterium] and Spirullina [blue-green algae] are sources of single cell protein
3 Plant cells do not show cellular totipotency and hence cannot be cultured
4 Gamma radiations are used to induce mutations in plants

Rapid clonal propagation of explant to obtain genetically identical plants is known as
1 somatic hybridization
2 micropropagation
3 protoplasts
4 meristem culture
Explanation:
To obtain a large number of genetically identical plants, explants are grown in a synthetic growth medium under aseptic conditions. It is called micropropagation as new plants are developed from a small explant.

Which of the following plant parts serve as source of explant for tissue culture?
1 Petal, leaves and flower buds
2 Ovaries and anther
3 Seeds and nodal segment
4 All of these
Explanation:
Any plant part can be used as explant since all the plant cells are totipotent. However, cells from meristematic regions are preferred due to their ability of rapid cell division.
