Tissue culture in plants is easier than in animals. Give reason.

Explanation

In animals, the tissues are more complex and require many proteins, hormones, etc., for their growth in addition to the nutrients. In plants, the tissues can be made to grow if proper nutrient medium is provided. Moreover, in plants, many cells are totipotent and are capable of cell division and cell differentiation even in adult plant.
In animals, only few kinds of cells are totipotent, which makes the tissue culture a more challenging task.
