To obtain virus - free healthy plants from a diseased one by tissue culture technique, which part/parts of the diseased plant will be taken?

Apical meristem only

Palisade parenchyma

Both apical and axillary meristems

Epidermis only

Solution

Both apical and axillary meristems

Both apical and axillary meristems are free of virus for the healthy plant cultivation because of strong interferon activity in this region. These tissue form a protective impermeable covering around themselves, which s non-penetrable by any pathogen. Hence, these tissue are used in the production of disease-free plants by tissue culture.

Some More Questions From Anatomy of Flowering Plants Chapter

State the location and function of different types of meristems.

Explain the process of secondary growth in the stems of woody angiosperms with the help of schematic diagrams. What is its significance?

Draw illustrations to bring out anatomical difference between:
(a) Monocot root and dicot root
(b) Monocot stem and dicot stem

Cut a transverse section of young stem of a plant from your school garden and observe it under the microscope. How would you ascertain whether it is a monocot stem or a dicot stem? Give reasons.

The transverse section of a plant material shows the following anatomical features:
(a) the vascular bundles are conjoint, scattered and surrounded by a sclerenchymatous bundle sheaths.
(b) phloem parenchyma is absent. What will you identify it as?
