B) Attainment of definite size and shape
C) Performing a distinct function
D) Ability to divide

A) A and B
B) A, C and D
C) B, C and D
D) A, B and C

Answer 1

Hint:Tissues are defined as a group of cells that carry out the same function and also belong to the same origin. Tissues are a part of both plants and animals but the types and functions are different in the two.

Complete answer:
In plants the tissues are divided into three systems- the epidermis, the ground tissue and the vascular tissue. The epidermis forms the outer surface of leaves and young plants, the vascular tissue comprises mainly the xylem and phloem and the ground tissue serves in the storage of nutrients. Plant tissue can also be divided into- permanent and meristematic tissue. Permanent tissues are those which have lost their ability to divide and occupy fixed positions in the plant body. They are again of three types- simple permanent tissue, complex permanent tissue and secretory or special tissue. Meristematic tissues are those that are in the state of active division. They are also differentiated based on their region of occurrence into- apical meristem, lateral meristem and intercalary meristem.

So the correct answer is (D) A, B and C.

Note: Plant tissues both the permanent and meristematic ones serve specialized roles in the plant and thus detailed knowledge about them is important. Because one of them helps in the growth and development of the plant parts whereas the other helps in formation of plant parts that help in its survival mainly by providing food and water.
