Question

What are plant tissues?

Answer 1

Plant Tissues:

1. Plant tissue is a group of cells having a common origin and usually performing a common function in a plant body.
2. Every plant tissue has a distinctive function and can be united with different tissues to form organs like roots, stalks, leaves, and flowers.
3. Plant tissues are divided into two categories: i) meristematic and ii) permanent tissues.

i) Meristematic tissues:

1. Plant growth is generally restricted to meristems, specialized regions of active cell division.
2. According to their position, apical, intercalary, and lateral meristems are the three types of meristems present in plants.

ii) Permanent tissues:

1. Permanent tissue cells do not usually divide any further.
2. Simple tissues are permanent tissues with all cells having the same structure and function.
3. Complex tissues are permanent tissues that contain various cell types.
4. Plants have parenchyma, collenchyma, and sclerenchyma as superficial tissues.
5. Plants have complex tissues called xylem and phloem.
