Multi cellular organisms are composed of many cells whereas unicellular organisms are composed of single cell. Multicellularity is indeed a progressive attribute of evolution where cells form tissue which forms organ and then organ system and finally an organism. Both multi cellular and unicellular organisms has advantages and disadvantages of their own. One of the main disadvantage of multi cellular organisms is that due to such a complex composition and functioning they require a large amount of energy for their maintenance and survival. Different organs and system require a huge amount of energy when it comes to comparison with unicellular organisms. A large amount of energy is also wasted in all these life processes. Though multi cellular organisms can survive in a variety of environmental conditions but then also their survival is difficult than any unicellular organism.

The options of the given question are:
method for DNA delivery
gene construct
efficient selection strategy
tissue culture system
Answer: Tissue culture system.
Explanation:
The role of tissue culture system is not much in case of the transgenic plant. The method of DNA delivery, efficient selection strategy and gene construct are involved in the plant transformation.
But plant tissue culture is not directly involved in the plant transformation. The plant tissue culture is the collection of the techniques which is used to maintain the growth of the plant cells and so it does not plays any important role in plant transformation.
The plant transformation is the introduction of the desired characters into the plant and then the growth of transformed plant takes place in the culture medium. This has no role in the plant transformation or has less role.
