Question

Disadvantages of tissue culture.

Answer 1

Explanation:

• Disadvantages of plant tissue culture

1. Complex and time consuming.
2. All the plants that are produce have the same genetic material so they, are equally vulnerable to environmental factor infections, and pests.
3. No new combinations of traits which only result from melotic division can be produced.
4. The genetic diversity of plants is reduced.

Answer 2

1. The setting up of a plant tissue culture laboratory is very expensive including it's machines and reagents

2. The experiments of tissue culture must be handled by highly trained people as the procedure requires special care and careful observations.

3. If all the plants are genetically similar, there is reduction in genetic diversity.

4. If a plant is susceptible to disease, all the plants of this cloned stock will share this undesirable trait and be susceptible to that particular disease.

5. The procedures depends on the type of species being cultured, hence there is need for trail and error method for any new species if there is no review about that species.

6. If precautions are not taken, the whole stock may be contaminated or infected.
