1.       Define tissues.

        Tissues are the group of cells that are similar or dissimilar in structure and origin, but perform similar functions.

2. What are the classifications of plant tissues?

              The plant tissues can be broadly classified into two, based on their ability

               1. Meristamatic tissue

               2. Permanent tissue.

 3. What are the classifications of plant tissues according to Sachs?
