After discussion of different levels of organisations, now I am going to start discussion about tissue.
Plant Tissue
Plants are the organisms who grow through out their life. The plant tissues are mainly divided in to two main types :- 1. Meristematic tissues 2. Permanent tissues.
1. Meristematic tissue ( Meristem ) :- Meristematic tissue is the group of actively dividing young cells. These cells contain more nuclear contents and less cytoplasmic content in it because they will have to divide itself through out life for growth of plant.
Main characteristics of meristematic tissue cells are as follows :-
- Cell wall of meristematic cell is thin.
- Inter cellular space is not visible.
- Large nucleus and less cytoplasm.
- Vacuoles are absent or very small in size.

That's all for today, we will meet tomorrow with types of meristematic tissue.
