The correct answer is option- 1, which states that plant tissues are of 3 types. This means that plant tissues can be classified into three broad categories. It is important to note that plant tissues are grouped based on their structure and functions. The three types of plant tissues are:

1. Meristematic Tissue: This tissue is responsible for the growth and development of plants.

2. Permanent Tissue: This tissue includes various types such as parenchyma, collenchyma, and sclerenchyma, which perform various functions like storage, support, and transportation.

3. Epidermal Tissue: This tissue covers the outermost layer of the plant and performs functions like protection and secretion.

It is worth mentioning that although there are further subcategories within these types, the fundamental classification of plant tissues is based on these three types.
