Question

To obtain virus-free healthy plants from a diseased one by tissue culture technique, which part/parts of the diseased plant will be taken?
A. Apical meristem only
B. Palisade parenchyma
C. Both apical and axillary meristems
D. Epidermis only

Answer 1

Hint: An area of cells equipped for division and development in the root and shoot tips in plants. Apical meristems offer ascent to the essential plant body and are liable for the expansion of the roots and shoots. An meristem that permits the creation of optional development tomahawks in the shoot frameworks of plants.

Complete answer:
An axillary bud is an early stage or organogenic shoot which lies torpid at the intersection of the stem and petiole of a plant. It emerges exogenously from the external layer of the cortex of the stem.
Axillary buds don't turn out to be effectively developing shoots on plants with solid apical strength (the propensity to develop only the terminal bud on the primary stem). Apical strength happens in light of the fact that the shoot apical meristem produces auxin which keeps axillary buds from developing. The axillary buds start creating when they are presented to less auxin, for instance if the plant normally has feeble apical strength, if apical predominance is broken by eliminating the terminal bud, or if the terminal bud has become far enough away for the auxin to have less of an impact.
Apical meristem is vital in stretching out both admittance to supplements and water by means of the roots and admittance to light energy through the leaves. Plants must grow in both of these headings so as to be effective. A few plants show apical predominance, in which just a single principle shoot apical meristem is the most unmistakable. In plants this way, there is a solitary primary trunk which scopes to extraordinary statues.

So, the correct answer is “option C”.

Note:
The apical meristem is found just beneath the root cap in the roots, as found in the picture underneath. The genuine apical meristem is a bunch of thickly pressed and undifferentiated cells. From these cells will come the entirety of the different cell structure the plant employments.Axillary buds can be utilized to separate if the plant is single-leafed or multi-leafed. Basically tally the quantity of leaves after an axillary bud. If there is just one leaf, at that point the plant is viewed as single-leafed, if not it is considered multi-leafed.
